Fucked up my system pretty bad whilst trying to install drivers (infosec.pub)

Hey guys,

Im a relatively new Linux user, so pardon the stupidity thats about to follow. I have an Asus gaming laptop on which I installed Debian 13/ testing. Everything worked well, until I tried installing new AMD drivers.

I followed this wiki article for the installation of the drivers. However after I ran the command

# apt-get install firmware-amd-graphics libgl1-mesa-dri libglx-mesa0 mesa-vulkan-drivers xserver-xorg-video-all

and rebooted my system, I was no longer able to access my Desktop ("unable to access Cinnamon session").

The good news is I can still access the terminal via Ctrl & alt & f2. However I am not able to reinstall cinnamon because I dont have network access (I think).

I might be wrong but I think thats because before rebooting I ran a VPN with killswitch enabled, which is now blocking my network access, but I have no idea how to disable this from the terminal.

Could you help a noob out to repair his system?

I would hate to reinstall and lose all my data :(

As far as reinstalling and losing your data, you may want to just backup /home to a USB disk now.

You'll want to figure out the VPN issue, so maybe post what you know about that. Also post ifconfig -a or ip addr show. Also the output of route for good measure. Can you ping anything? Is it just a nameserver issue (try pinging 8.8.8.8 and kernel.org, for instance)?

Once you have network access, I'd install tmux if you're going to be spending any significant time debugging in the terminal :)

Also post ifconfig -a or ip addr show.

ifconfig is deprecated for a long time I think. Not even sure if some Debian package still provides it. I've switched to ip a and ip r and cat /etc/resolv.conf to look at such issues as OP has.

You should be able to use nmtui tool in the text terminal to activate your network connection. From the terminal you can also use the startx command to try and see if that would show you a GUI or other useful errors.

the apt logs probably contain the versions you had before that. you could try and go back.

in any case: make backups before updates to prevent this in the future. even an incomplete backup can be better than none.

If secureboot is enabled try disabling it. If disabling secureboot resolves the issue re-enable secureboot and add the dkms signing key with mokutil: https://wiki.debian.org/SecureBoot#Making_DKMS_modules_signing_by_DKMS_signing_key_usable_with_the_secure_boot

This has nothing to do with secureboot, as the system boots fine according to the explanation.

That doesn't mean it is loading dynamic kernel modules, which also require enrolling a machine owner key.
