So create the stupid directory it searches for and be done with it. That is all them .d's are a configuration directory to put files into to be loaded instead of editing the system configuration file that can be overwritten on update/upgrade losing the changes you want to have in the default behavior contained in the system file. I have no .d directory on my install either and it works fine.

root@9600k:~# ll /etc/inittab 
4 -rw-r--r-- 1 root root 2348 Jan  7 05:26 /etc/inittab

I do however have a modules-load.d which contains a file that is used to load cups related options.

root@9600k:~# ll /etc/modules*
4 -rw-r--r-- 1 root root  295 Jan 24 20:23 /etc/modules

/etc/modules-load.d:
total 4
4 -rw-r--r-- 1 root root 119 Jan 16 04:53 cups-filters.conf

Yes the *nix method of do one thing and do it well, a concept seemingly lost to many of today's programmers. And their let's copy ever GD bad idea out there chasing the new shinney. I am shocked the fools have not just dumped that AI garbage into everything yet like they usually do with such trash.

I think it was the sddm-theme-debian-maui that did that to me, remove it and install the plain sddm-theme-maui to see if it gets rid of that foolishness. At least it was one of them -debian pieces of junk that did it to me.

You are welcome, yes I can see why give it a couple of more years, they will find some other new shinny to chase and you will get to learn another new system of doing it. Been like that for the twenty-five plus years I have been using it, I have every confidence they will do it yet again.

Of course it is, since Devuan has nothing to do with the desktop chosen and their display manager they use to login with. They just provide the software used by them for that purpose.

Well that is half the battle won, for the rest. Edit the file /etc/default/grub for this line.

root@9600k:~# grep -i prober /etc/default/grub
# probably want to run os-prober. However, if your computer is a host
# os-prober can cause damage to those guest OSes as it mounts
GRUB_DISABLE_OS_PROBER=true

Change it to false so it will probe for other OSs as you want then update-grub to have it done. Do this as root user or with sudo in front of the command when it does the updating you will see the OSs it will put in the menu listed in it output.

Edit: That of course assumes you have the menu enabled and a timeout set for it to do so.

GRUB_TIMEOUT=5

Two ways to do it.

Use dpkg --contents (= dpkg-deb --contents) to list archive files contents.

The first using apt-file the package does not need to be installed for it to work and find the contents of packages. The second the packages needs to be installed on the machine. As you can see there is not a lot to the package I doubt it is usable for conversion of anything and looking at the information about it seems to confirm it is only a library that supports the format.

Description: HEIF and AVIF file format decoder and encoder - gdk-pixbuf loader
 libheif is an ISO/IEC 23008-12:2017 HEIF and AVIF (AV1 Image File Format) file
 format decoder and encoder. There is partial support for ISO/IEC 23008-12:2022
 (2nd Edition) capabilities.
 .
 HEIF and AVIF are new image file formats employing HEVC (H.265) or AV1 image
 coding, respectively, for the best compression ratios currently possible.
 .
 libheif supports various codecs provided by plugins for image decoding and
 encoding.
 .
 A gdk-pixbuf loader module for applications such as "gpicview" and "pcmanfm"
 is provided by this package.

Give an actual conversion program like ImageMagick a go you will likely have better reult in getting something to start and have a hope of seeing it it support the conversion from that format. Though the format is not specifically listed it says over 100 supported..

Yeah but who has any of them laying around to waste on an installer. And good luck just going out and buying them anywhere, need to be ordered online here. I have some dvd blanks that have sat unused for years but no cd that I know off. I gave up on the dvd after discovering what garbage they are. Tried to get some files off an about year old disks and what a mess, it was errors everywhere. That is when I switched to hard drives for my storage needs they very rarely fail and I have so many backups. Fours sets of zfs raidz in four different machines I have accumulated as leftovers when upgraded over the years. That I never need to worry about that massive amount of data I have stored. Well I do being the paranoid about my computing freak I am, I backup my installs all the time. As a cron job that runs every two hours, before any major upgrade with a cloning to external drive then booted in my duplicate machine I have to confirm the backup worked then upgrade. And/or backup to the internal backup drive as well, I take my data safety seriously.

The only ISO I have ever found that will not work for install with Ventoy is the Devuan, supposedly the same ISO except for branding/sources with the equivalent Debian on it boots and installs perfectly..

Depends on how it is setup by the replacement device used. If it is a direct connection to the internal Hard Drive controller allowing it to boot the machine then it can be damn useful. That type of arrangement can be the same as replacing the internal hard drive. You need to determine the way it connects to the machine, the speed of the connection it gets when in it. But generally it is good to try and use it as your install to boot from to see if it will speed up your machine. If Camtaf is correct with the specifications he posts for your machine and it has four slots with maximum capacity of 16GB for the machine then the ram you show is incorrect for your machine as the most it will take are 4GB higher speed modules and you link to are 8GB. Before buying anything make certain of the return policies in the event what you get does not work with your machine.

Now I have looked for them this place suggests 32GB or 4 X 8GB modules are supported.

As does the Kingston web site.

https://www.kingston.com/en/memory/sear … 530-series

And this German site says the same thing as well.

https://www.compuram.biz/memory/lenovo/ … quad-core/

The one thing they all have in common is the 1600mhz for the ram speed, if replacing your ram in the end then this is the speed you need to get to run it at its full potential. And as I have already said make certain any place you buy from has no questions asked no hassle returns policy. There  is no sense wasting your money if you find what you have bought does not work properly and they will not let you return it.

THE most sensible set of rules for any forum I have ever seen just about perfection.

That depends on a package in the unstable/ceres that does not exist.

root@9600k:~# apt install -s -t unstable  python3-apt

Some packages could not be installed. This may mean that you have
