Hello:
Just came across this article from The Register, one of my usual reading spots every morn.
As I started to read it, I immediately recalled Mike-thinky's plight.
Just a small tidbit to whet your appetite:
Three of the last four new laptops that have landed on The Reg FOSS desk came with Windows' Bitlocker FDE turned on by default. (The only one that didn't was Tuxedo Computers' Stellaris gen 4, a gaming laptop with a multicolor illuminated mechanical keyboard. As a machine intended to run Linux, that's not really a surprise.)
Many users might never even notice it, unless they try to dual-boot the computer with a non-Windows OS and find that nothing else can read the disk. Never fear: we have described how to turn it off and make such a machine ready to dual-boot.
I for one won't be letting go of my legacy BIOS booting box anytime soon, even if I have to resort to learning how to spin a custom tailored kernel for it.
But ...
How long will I be able to hold out?
Best,
A.

Glad you were able to work it out.
I see that there are only 36 open issues at the CUPS GitHub page and only 3 have not been looked at/sorted/classified yet.
The last 2 being from this month and one from less than a month ago.

You may want to have a read here and here.

Devuan Package Information page, so I have to assume that you downloaded it from another source.

You run Devuan 4.0.
Devuan is Debian without the systemd crap in it.
As tailscale does not seem to be in the Devuan repositories, I don't think there's a workaround.

Hello:
... tried to find an address at which to report the Dead Fish that is the CUPS driver ...
From what I see, issues have to be reported to the CUPS project issues page.
For starters you have to log-in and to do that you have to sign up/join/register with GitHub.
Once you get that (needed) administrative crap out of the way, you log-in and open a new issue.
As you may gather, given the complexity of the problem, the instructions for filing an issue must be followed to the letter.
ie: Like when you file a bug with Debian, in the hope it may be looked at eventually.
Note:
I recall that an HP Colour Laser printer I used 20+ years ago had to be calibrated every so often or when one of the (absurdly expensive) toner deposits had to be replaced, otherwise everything was off colour wise, more than the usual.
This Brother printer has something like that? Never seen one so I don't have a clue.

A.
#841 Re: Desktop and Multimedia » [SOLVED] Fixing broken Brother DCP-L3510CDW Printer Installation (howto) » 2023-02-05 15:04:27

Probably (no idea) and no never (experience talking).
Which is why there's a whole industry dedicated to extract money from those who need to use standard/universally accepted profiles.
ie: that will allow printed/displayed pages to look/be seen as being the same, everywhere.
... a superb find.
I'm glad you think so.
In any case, it seems that there is no shortage of people attempting to bowl the same sticky wicket, so to speak.
From the little I have read on the matter, it has been, is and will continue to be so till something breaks.
As a result, there are quite a few apparently viable (?) alternatives, albeit with widely varying degrees of success, as usual.
Check https://www.color.org/opensource.xalter and https://www.color.org/creatingprofiles.xalter
Something's got to give.
... need to find the way to communicate ...
... that their current Brother DCP-L3510CDW PPD is pants ...
Like I mentioned, I suspect that not only they know but that it is the default option for your printer.
You may want to spend some time looking through the Brother catalogue for a model which could meet the following criteria:
1. it is more expensive
2. it has more options
3. uses a similar ink/cartdrige/printing system
4. repeatedly uses the term professional in the User's manual. 8^D
If you don't find a suitable one, check to see if you can find out which brands are really Brother units with another label and look among them.
Maybe some printer repair shop or DIY page on the web has that data.
If and when you find it, get the ICC file and see how it works with your printer.
Best,
A.

Hello:
Thanks for the link ...
You're welcome.
... well used to Pantones ...
... up to speed with the issues.
Yes, the Pantone Pirates ...
You seem to have all that covered then.
... main issue seems to be the need to have an ICC profile to cover RGB-to-CYMK ...
... Brother is printing the wrong colours.
Well ...
In my limited experience, once these things start to edge into professional areas you find blocks and removing them is very costly because that is what the blocks are there for.
eg: specifying exact colours for industry wide use within a specific professional area like architecture.
When I was still a student, I was enthralled by this huge Pantone colour catalogue, till I asked how much it cost. 8^°
If Brother, a company perfectly capable of generating the correct ICC profile for this printer does not do it, it is because it is not interested.
eg: maybe they don't want this printer competing with other printers they manufacture, under their own brand or rebranded for third parties.
It is always a $$$ issue, they are not dumb.
Colour wise, I went by eye so to speak for many years and managed well enough.
These days you go to a hardware store with a peeled off patch from a wall you need to paint and in a while you get a 4lt. can of the right colour, mixed to order.
While I was looking to try to understand how all this ICC works, I came across a web page which may be interesting for to you to check:
https://rawpedia.rawtherapee.com/ICC_Profile_Creator
It is related to a raw image processing program called RawTherapee.
If it exists it is because more than one commercial application (expensive, obviously) exists.
This one is free to use.
Hope that helps.

A.

... fact that there is less problems with the CMYK driver than the RGB driver points in the same direction ...
... how do I get such a file?
No idea ...
I just do B/W ... 8^°
But I came across this, have not read it but it smells right, so to speak.
ie: there's an explanation of sorts and it says [Solved].
---
Why do some printers print RGB and some CMYK if all printers are CMYK..?
https://community.adobe.com/t5/acrobat- … p/10411460
---
Depending upon the print driver's settings, many print drivers will not do a simply ICC profile-based RGB to CMYK conversion, but rather, use “secret sauce techniques” to try to punch up the colors, especially what one may describe as “office colors” such as the bright colors that you may typically see in a PowerPoint presentation or Excel spreadsheet.
Maybe the Adobe chaps can give you more ideas than the Brothers ...

Hello:
HP printed it perfectly & the damned Brother will not!
When I decided to take an early retirement offer, I found myself needing a printer.
The little printing I've needed year in/year out was done at the office at my employer's expense, maybe 75/100 pages a year.
The last printer I had at home was a DeskJet HP520, purchased in 1995 and retired in 2005.
This time I looked for the simplest/least expensive B/W laser I could find, eventually purchasing a Samsung M2020W.
I went through hell trying to get it to work with my Linux box, I think running Ubuntu at the time.
Nothing worked and was about to give up when something happened ...
------------------------> I installed CUPS! 8^D
Granted, the driver does not seem (?) to be as complete as the the one HP wrote for MS, but it works *prefectly* well.
Not *one* issue since I installed it and it's worked through quite a few distributions before I settled on Devuan: Debian, Ubuntu, Mint, PCLinuxOS, #! ...
Save some issues when printing from LO, but that is just typical LO behaviour of not fixing bugs and letting them fester.
I think that any problem CUPS may have with a specific printer lies in the structure of the PPD and/or colour profile files.
ie: if they are not properly written and match exactly with the printer's hardware, you get issues such as the ones you are going through.
Some OEMs actually do a good job and provide well written PPDs and others do not.
If there's only *one* good thing I can say about Apple it is regarding CUPS.

A.

#847 Re: Hardware & System Configuration » Dying machine? » 2023-02-01 00:08:33
Hello:
... AM2+ platform is about a decade old now ...
“Reports of my death have been greatly exaggerated” Wrongly attributed to Samuel Clemens (1835-1910).
I run Devuan Beowulf on a Sun Microsystems Ultra 24 WS purchased in late 2015, second hand with ~ 4 years' use already on it.
It has been running without issues for the past eight years on an Intel Q9550, 8.0Gb RAM, 4xSAS drives and a pair of Nvidia FX580s.
So it is at least 13 year old rig.
I also run Devuan Beowulf on an Asus 1000HE w/2Gb RAM and the original HDD, also purchased second hand in 2010 with less than a years use on it.
Some plastics and a USB port went bad a couple of years ago so I snapped up a twin for US$50, transplanted healthy plastics and motherboard, sold the twin's lid/screen making a nifty US$30 profit and never had to look back. Only problem is that the battery pack/s are rather flaky.
Not bad for a 14 year old economy netbook ...
Many years ago I purchased a box of eight 9.1Gb Ultra SCSI IBM drives from a chap who had been tasked with physically destroying some hardware that was being retired. Of the eight drives, only one had issues, the rest went on to work for me for another 5 years.
My longest lasting harware?
A Umax S-6E SCSI scanner, which I purchased new in 1996 and works perfectly well ...
Moral of the story?
Decent hardware can and often will last way beyond what people, driven by the dazzle and hype of the newest and fastest expect.

Hello fsr:
apt rdepends zeitgeist will show packages that depend on zeitgeist.
Yes, but that will only tell me if any package installed in a system has zeitgeist as a dependancy.
I was referring to a scan of the whole Devuan package database which has that information.
Just have to weed it out but I don't have a clue.
I have never (ever) been able to make any sense of regex but I'm sure there's a way.
Adding a reverse dependency search box to do that would be a great addition to the database page, very useful in instances like this one.
Which I fear will become the norm.
Maybe some good tips here: https://dev1galaxy.org/viewtopic.php?id=511
I'll have a look.

Hello:
Good idea, but I think (like in the case of your example) that it may be more a dependency thing.
eg: my box runs Devuan Beowulf with a backported kernel.
~$ uname -a
Linux devuan 5.10.0-0.deb10.16-amd64 #1 SMP Debian 5.10.127-2~bpo10+1 (2022-07-28) x86_64 GNU/Linux
~$ I don't have zeitgeist installed.
~$ apt list | grep installed | grep -i zeitgeist
--- snip ---
~$ uname -aBut if I ask aptitude about zeitgeist, I get this information:
~$ aptitude why zeitgeist
i desktop-base Suggests gnome | kde-standard | xfce4 | wmaker
p gnome Depends totem-plugins
p totem-plugins Suggests totem-plugin-zeitgeist
p totem-plugin-zeitgeist Depends libzeitgeist-2.0-0 (>= 0.3.2)
p libzeitgeist-2.0-0 Suggests zeitgeist-core | zeitgeist
~$ I wonder if there's a way to scan the whole Debian/Devuan package information database to filter the packages that list zeitgeist (or its libraries) as a suggests or depends.
It would be really interesting to see what comes up.
Any ideas?
Maybe contacting the database maintainer/s?

As you are on kernel version 5.10 your Mediatek card has no driver, you need version 5.12.
lspci --- snip --- 04:00.0 Network controller: MEDIATEK Corp. Device 7961 --- snip ---
Happens often ...
New hardware (in this case Mediatek 7961) and no available Linux drivers/modules save in the latest kernels (in this case version 5.12) while your installation runs on an up to date (version 5.10) albeit with no driver for your new hardware.
Which is why it is good practise to check driver availability before purchasing new equipment. 8^)
Just follow HoaS's instructions and your WiFi/Bluetooth driver issue should be solved.
Keep us posted.
