Hello:
... to start with a minimal install ...
Same here.
... verifying the check sum seemed to match ...
It has to match exacly.
Seemed won't do.
Just pulling your leg ... =-D
Not sure what went wrong.
In my limited experience, the first check you do is on the *.iso file you downloaded.
Then you do a check on ther file burned on the CD/DVD or USB.
I found a way to do this here:
https://askubuntu.com/questions/547332/ … -boot-disk
To check the integrity of a usb boot disk, first find the size of the iso image with
stat -c '%s' imagename.isoThis will output an image size which you can enter in place of <imagesize> in the command below.
The next command sends (through a pipe) all bytes corresponding to the size of the image to the md5sum command:sudo head -c <imagesize> /dev/sdb1 | md5sumYou can compare this with the md5sum of your .iso file.
md5sum imagename.iso
If md5sums are different then there was an issue while copying the data.
If md5sums are the same, you have successfully checked data integrity on your usb disk!
The third and final step is to boot the installaiton *.iso and run a check on the installation media itself with the tool available in the menu.
Although, as we have seen in this thread, it can sometimes give a false positive.
Cheers,
A.
Hello:
... 2.1 minimal-live isos both have the same isolinux.bin.
OK.
... amd64 and i386 are both built using the same xorriso/mkisofs command.
OK.
... desktop-live i386 and amd64 use slightly different commands ...
OK.
It's all rather over my head/pay grade.
Eventually, I guess ...
... surprised that the isolinux.bin in the 2.1 minimal-lives are the same as the 2.0.0 you posted.
f03d6ecc57dad4524a0cab76b7afab41
I computed them in a teminal so it would be hard to make a typo and checked the values twice.
A coincidence?
This isolinux.bin only came up because of my checking the installation media with the install's verification routine.
The *.iso file was intact after download and was correctly written to media.
But as you pointed out, the issue did not come up in the 2.0.0 *.isos because isolinux.bin was not in the respective md5sum.txt file.
It was not scanned, ergo no error was computed. =-)
... problem with installing software is not related to isolinux.bin. Sometimes the installer fails ...
Agreed ...
As I mentioned in my email, due to a USB stick with not enough space.
I suppose then that all is well?
Thanks for taking the time to look into this.
Best,
A.
Hello:
... took the easy way out and excluded isolinux.bin from the md5sum.txt file.
Maybe not the easy way out.
It probably slipped past them.
Now it has to get fixed, somehow.
Has it been the same with previous versions?
... one way to avoid a false negative
Indeed ... 8^* !
That with respect to the 2.0.0 *.isos.
But with respect to the 2.1 *.isos, if the 2.1_amd64 version is supposed to be the same (?) as the 2.1_i386 version, why are they different? (ie: produce different md5sums)
ie: I'm assuming that they are the *exact* same file because they are not arch specific, as fsmithred pointed out earlier.
This would imply (?) that whatever happened to the original source file was affected differently when going through the process of compiling the respective *.iso.
Am I making sense here?
The plot seems to thicken ...

Best,
A.
Hello:
... ISO sets of 2.0.0 and 2.1 where produced in different ways ...
OK.
But if the isolinux.bin files are not (fsmithred says, I wouldn't know) arch specific, why is the 2.1_amd64 version different from the 2.1_i386?
ie: I'm assuming that they are different because they produce different md5sums but maybe functionally they are the same.
To top it off, neither of the md5sums they produce are the same md5sum in the md5sum.txt file.
Makes no sense ...
A re-release of the latter would indeed be a good thing.
Sure ...
But I'd pull them from the servers asap to do some forensics on those two files to see just what happened.
Cannot be too careful.
thanks ...
No need.
You are the guys moving the Dev1 project along.

Hello:
... that mkisofs does something to the first 64 bytes on transfer from disk to CD/DVD image, i.e. when the .iso is created.
I have seen this in the ascii 2.1 netinstall *.iso files only.
The ascii 2.0.0 netinstall *.iso files don't seem to have this problem.
ie: media verification using the tool available within the 2.0.0 netinstall media does not fail and the isolinux.bin file produces the correct md5sum.
Best,
A.
Hello:
I'm looking into this.
Thank you.
... some collected md5sums on isolinux.bin that I have in various places.
... sha256sums on the netinstall isos and they are correct.
Yes, that's what seems (to me) odd.
I was expecting this to be just a bad download, but no.
Here's what I have.
I mounted the *.iso files with AcetoneISO and checked the respective isolinux.bin files.

Since the *.iso files are intact and the isolinux.bin files are not arch specific what I think we are seeing in the sample I am posting about is that there are (at least) two versions but none of them with the correct md5sum ie: 81d876d6234d3ca002390e7cb361bb61 ./isolinux/isolinux.bin
I have not checked other sources as I expect they are mirrored.

Hello:
... install pcmanfm or remove its non-working menu entry?
... other menu items failed.
Has anything else happened with this Derivative?
It looks really great (reminds me of my favourite # !) but to be a switchblade OS it needs to have a fully functional file manager (or at least MC installed) and some sort of auto network configuration or scripts to get things running.
Otherwise it's sort of crippled.
Any news?
Thanks in advance,

Hello:
I'm trying to put together a very small Devuan install to replace a TCCore installation which lacks the Nouveau drivers I need for my NVidia cards.
To do that, I downloaded the devuan_ascii_2.1_i386_netinst.iso file and once I checked the SHA256SUM, burned it with Xfburn and attempted to install.
The installation failed toward the end with a pop-up notice about not being able to install the software.
To me, it was rather obvious the DVD was at fault and with Xfburn having no integrity check, I booted up the DVD again to check the its integrity and yes, it turned out to be bad.
The isolinux file was compromised.
So I just burned another DVD, this time checking that the DVD drive was clean and burning the *.iso file at a lower speed.
This time I checked the integrity of the DVD before attempting the installation and it also also turned out to be bad but ...
It was bad at the same point: the isolinux file was compromised.
Fearing the worse (a new $ATA DVD burner) I decidec to dd the *.iso file on to a USB stick to install from there.
devuan:~$ sudo dd bs=4M if=devuan_ascii_2.1_i386_netinst.iso of=/dev/sdbJust in case, this time I booted up and checked the DVD's integrity first.
Guess what?
It also failed the test and with the same issue: a compromised isolinux file.
---
Edit I:
The compromised /isolinux file is ./isolinux/isolinux.bin.
This is from the *.iso file dd'd to a USB stick.
According to md5sum.txt, this it should compute thus:
81d876d6234d3ca002390e7cb361bb61 ./isolinux/isolinux.bin
But File -> Properties -> Digests says it is 3b36f20bc14cf4ad0f046962c4414221.
The specific *.iso file is timestamped as Devuan GNU/Linux 2.1 (ascii) i386 NETINSTALL - 2019-10-21 23:05:54 UTC
---
Edit II:
If I directly mount the downloaded and verified *.iso file with Acetone ISO and check ./isolinux/isolinux.bin with Properties -> Digests, it also says it computes as 3b36f20bc14cf4ad0f046962c4414221 instead of what md5sum.txt states.
ie: 81d876d6234d3ca002390e7cb361bb61, so it would not seem to be an issue with the download, its dd'ing to the USB stick or burning to a DVD.
Could it possibly be a compromised file within the *.iso?
---
I've never come across something like this before: it has always been a bad *.iso file or a bad burn due to the drive, the media or the software/speed.
But a bad dd?
Any help with this will be appreciated.
Thanks in advance,
A.
Hello:
Hello:
I have not seen any indication of its being assigned.
I'm running the last available Devuan 4.9.0.11-686-pae SMP Debian 4.9.189-3+deb9u1 (2089-09-20) i686 and the problem subsists.
Will this ever get fixed or will it end up as part of the 'won't fix' crud that ends up accumulating inside the code because it is not considered worth correcting?

Hello:
Wine can be rather a PITA.
Have you tried the alternative of setting up VirtualBox?
You run all your MS applications in a VM.
XPSP3, for example.
Cheers,

Hello:
is that what you're looking for?
No ...
That's not it.
What I need/want (and opine that any FM should have) is the function MS had/has in Windows Explorer: the Right Click -> Send To -> Any Folder action.
You can select either Copy or Move and then Browse, where you get another window to quickly find where you wanted the file to go.
You can then easily repeat the same action faster as the different destinations stay cached and show up in a drop down box.
Cheers,
A.
Hello:
I had a similar symptom once, and in my case ...
Thanks for the heads up. =-)
I will check anyhow.
I finally found an applicable case. See: https://superuser.com/questions/363337/ … -processes
It solves a similar case with a Conky variable I had overlooked: top_io. See: http://conky.sourceforge.net/variables.html
${top_io name 1} ${top_io io_perc 1} ${top_io cpu 1} ${top_io mem 1}top_io takes arguments in the form: top_io (name) (number).
Processes are sorted by the amount of I/O the process has done during the update interval, which is what (number) represents.
The types are: "name", "pid", "cpu", "mem", "mem_res", "mem_vsize", "time", "uid", "user", "io_perc", "io_read" and "io_write".
There can be a max of 10 processes listed.
I used it with just NAME, CPU and MEM, which is just the information I needed.
Four processes is probably too many for my use and I'll trim it eventually:
Disk I/O
${hr 2}
NAME${alignr}CPU MEM
${top_io name 1}${alignr}${top_io cpu 1} ${top_io mem 1}
${top_io name 2}${alignr}${top_io cpu 2} ${top_io mem 2}
${top_io name 3}${alignr}${top_io cpu 3} ${top_io mem 3}
${top_io name 4}${alignr}${top_io cpu 4} ${top_io mem 4}Cheers,

Hello:
So is conky really, you are only going to get information on the event as it happens ...
Indeed, which is more or less what I want to do.
Just check out that it is nothing that looks out of the ordinary/expected, so to speak.
If it were, I'd then go on to check the usual files in /var/log to see what was going on.
... logging the event you have some real data to go on that may help you figure out the issue.
Yes, you are quite right there. =-)
But unless my rig's configuration has gone astray, I do not really expect unusual stuff.
What got me asking about this is that the process, which I expect is BackInTime or TimeShift related, is not getting shown in conky (don't know why).
It happened this morning about an hour past my boot-time and I ran iotop to see what was working.
In this particular case it was BackInTime cleaning up excess/older snapsots (actually it was rsync).
Thnaks a lot for your input.
Best,
A.
... might be what you are looking for.

Thanks.
I'll have a look.
But logging IOTOP is sort of after the fact.

Hello:
... this in your conkyrc.
Thanks, but I'm afraid it won't do.
What I need is to be able to look at my screen (eg: conky) and see something similar to what this does but for disc access/activity.
It gives me data on the top 5 processes and the % CPU time they take up.
Unfortunately, for some reason backintime and timeshift do not show up and maybe some other activity does not either.
And I'd really like to know what is writing to my drives when more than usual activity is heard.
TOP 5 PROCESSES
${hr 2}
$processes processes ($running_processes running)
${alignr}${top_mem 1} %
${top_mem name 2}${alignr}${top mem 2} %
${top_mem name 3}${alignr}${top mem 3} %
${top_mem name 4}${alignr}${top mem 4} %
${top_mem name 5}${alignr}${top mem 5} %
${top_mem name 6}${alignr}${top mem 6} %I don't need to check anything but who (process/programme) and where (disk drive/partition).
So if I hear unusual drive activity, this will give show me if it is something I want/need (eg: backintime/timeshift) or something else I should be aware of.
Most utilities I have found are benchmark oriented, designed to check if there are bottlenecks and such but I've not found anything security oriented (?) like my use would seem to be.
Maybe iotop might do but I cannot get it to run in conky nor have I found an example online.
Thanks for your input.

Hello:
... searching for examples of Thunar Custom Actions?
Yes, that's the first thing I thought of.
No luck.
Someone may have already worked it out.
I know there's a long thread about this at forums.debian.net
No, I haven't found anyone with a solution.
... has the feature you want, but it comes at a high price. (kde cruft)
Thanks but I'll pass on that one. =-)
I miss that feature, too.
It's incredible that this very useful feature has not been implemented in every FM out there, it's not that it has not been asked for quite a bit as that long thread shows.
Another feature, sorely needed in XFCE as icons have an atavistic tendency to position themselves as they please on the desktop is the Right Click -> Arrange Icons By -> Align to Grid for the desktop.
For years it has been been asked for but been systematically ignored.
All sorts of complicated/complex workarounds have been suggested but they ended up being a difficult/awkward solution to implement to solve what seems to be a simple problem.
... open two thunar windows and drag files from one to the other.
... set the Location Selector to Pathbar style, you can drag files from the main panel to the buttons ...
Yes, I thought of that.
Mate has the functionality you want ...
Thanks for the heads up.
Konqueror from TDE (Trinity Desktop Environment) can do it.
... better than both KDE4/5 and XFCE4 ...
... TDE is really lightweight DE and XFCE4 is wasting performance ...
I'll have a look at that.
Thanks.
Best,
A.
Hello:
There is iotop ...
Thanks, it could be what I need.
It seems more like a disk performance monitor but the data I need could probably be obtained from the output ...
TID PRIO USER DISK READ DISK WRITE SWAPIN IO> COMMAND ... using data from just TID/PID, USER and COMMAND.
... but you would have to either leave it running or pipe it to conky.
The best idea would be to pipe it to Conky so when I hear the drives I can just look at the display and see who is writing to disk.
I've looked around but have not been able to find an example of Conky using iotop and just a couple of posts from long ago asking.
Would you have one?
Thanks in advance,
A.

Hello:
A thing I miss from MS Windows Explorer (in XP) is the Right Click -> Send To -> Any Folder action which I used often.
The convenience of being able to select either Copy or Move and then Browse to quickly find where you wanted the file to go was really great and IMO, very efficient when the time came to archive the files and data accumulated over different folders and drives.
I have been searching to see if this same action could be replicated in Thunar but have come up empty handed.
Is this possible?
Any one done it?
Thanks in advance,

Yes, I do too.
I've come to see sudo as a rather dangerous thing if used (or rather set up) lightly.
It's something I picked up at the PCLinux OS forum.
I only use sudo along with specific user_xxxx files in sudoers.d which are set up just for for me to do routine things which need admin rights.
eg: dmesg, updatedb, shutdown/reboot, linsssd and such.
As the package is actually already installed, it won't do anything, except marking it in the database as manually installed and therefore not subject to an auto-prune event. Which is what you're after
Yes, I was about to ask with respect to marking files as manually installed and the effect is had.
Thanks a lot for your input.

Hello:
I.e., if you don't use the autoremove command, they're still installed.
Indeed ... =-D !
I did think of that too.
But ...
At some time or another ie: a week, a month or even a year later, I surely will have to use apt-get autoremove for something or other.

And that's when things will go south very quickly.
Isn't this so?

Hello:
If you install the packages individually, you can remove them individually.
OK.
... even do this if the packages were automatically installed ...
Cannot seem to get it done.

The following packages were automatically installed and are no longer required:
gtk2-engines-xfce libical2 libkeybinder-3.0-0 libxfce4ui-utils xfce4-appfinder xfce4-pulseaudio-plugin
Use 'sudo apt autoremove' to remove them.
The following packages will be REMOVED:

0 upgraded, 0 newly installed, 2 to remove and 0 not upgraded.
After this operation, 5723 kB disk space will be freed.
Do you want to continue? [Y/n] n
Abort.
groucho@devuan:~$ But this seems to be a Devuan/Debian thing as I have been told that in other distributions (eg: fedora) you can uninstall orage without much ado.
I could always uninstall orage and then reinstall the packages which were removed (xfce4 gtk2-engines-xfce libical2 libkeybinder-3.0-0 libxfce4ui-utils xfce4-appfinder xfce4-pulseaudio-plugin) but then re-installing xfce4 would drag along orage again.
Catch22?
