I dunno. You downgraded some pretty major core Linux system libraries, like this big one one (and others):

Code:

dpkg: warning: downgrading libc6:amd64 from 2.32-0ubuntu3.1 to 2.31-0ubuntu9.2

Have you tried recovery mode from the Grub menu and running sudo apt update and sudo apt full-upgrade ?
This should want to re-install the current versions, unless you pinned the old versions to keep them from being upgraded back to the stock versions.

The actual errors are mostly pertaining to the 32 bit versions of these packages (ie Steam or Wine related stuff) and are probably not effecting system booting but downgrading all those core system level libraries definitely is.

You added a PPA providing the current release of Kodi. So, yes, the new version of it would become part of your normal updates. You still have to click 'upgrade all' or otherwise confirm things to do this, so it really isn't an 'auto-upgrade'.
Either you could have used ppa-purge to revert back to the stock 18.8 that came from the official ubuntu repos, or 'pinned' the current version via Synaptic, Muon, or command-line.

BUT, if you can run apt to update the system, it *should* want to install the current versions back.

Thank you for the help @claydoh, I really appreciate it.

Recovery mode also does not boot, it always hangs soon after that message is displayed:

Code:

/lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.32' not found (required by /lib/x86_64-linux-gnu/libsystemd.so.0)

Is there a way to just unpack some deb into the system so this error does not occur, so I can run the recovery mode to update the system?

Yep I added Kodi's ppa. I ran ppa-purge and reverted it but the issue with those 3 packages I mentioned remained, because of some needed dependencies for them not being available anywhere for the previous versions I needed. So I started messing around and... well, the result is at sight!

Oh the auto-update I mention is because I use an AI that analyses the available updates and chooses according to its parameters. Or, in other words, I just run on the terminal the command:

Code:

sudo apt full-upgrade -y

IMO, the best and quickest way out is to do a fresh install of 20.04.2. Besides 20.10's EOL is this July. 20.04's is 2023 or 2025.

It will take about 20 minutes to do fresh install and about 2 hrs or so to reconfigure it to your liking, adding and removing apps and such. How much time have you spent already? And, had you been using BTRFS it would have taken you only a couple minutes to restore to a working system.

Thank you very much for the help @GreyGeek, very welcome as always.

I ended up reinstalling 20.10 over because 20.04 has a huge wifi problem in my laptop and I have to replace NetworkManager with Wicd to get it working. I don't know if in the point releases it has been fixed but I just wanted to get things working and the fastest way was to just replace the system files and a couple of folders and files in /etc, and running a line to install my apps (I'm always updating it in case something like this happens). So I did that and now all is back to normal, exception made to some addons in Kodi that return the error on the log:

Code:

Error Contents: No module named Cryptodome.Cipher

and I cannot figure out what could be missing. But I will not risk installing Kodi's official ppa again, I've had enough of that for sure.

probably one of your addons needs to be reinstalled, or the Cryptodome python bits are needed
NBot sure if it needs to be an internal python module installed with the addons installer, or if it needs to be done using pip, or systemwide with apt.

Code:

$ apt search cryptodome
Sorting... Done
Full Text Search... Done
python-pycryptodome/focal 3.6.1-2build4 amd64
cryptographic Python library (Python 2)

python-pycryptodome-doc/focal,focal 3.6.1-2build4 all
cryptographic Python library (documentation)

[COLOR=#ff0000][B]python3-pycryptodome[/B][/COLOR]/focal 3.6.1-2build4 amd64
cryptographic Python library (Python 3)

I suggest reinstalling one of the addons that needs this, it should be pulled in, and that way it will go into the place where Kodi sees it.

I tried installing python-pycryptodome both systemwide with apt and in user's folder with pip but no luck. It had something to do with going from Kodi 18.8 to 18.9 I guess, at least after installing Kodi 18.9 it installed python-pycryptodome as a dependency and the addons started working.

With that said I had to install Kodi's ppa, install the specific version of Kodi 18.9 along with old packages of kodi-inputstream-adaptive, kodi-inputstream-rtmp and kodi-pvr-iptvsimple I got manually, remove the ppa and mark hold all Kodi's packages so no more 'bad luck' would come in the future.
