I'm still a fairly new Linux-user (on Tuxedo OS), and I just ran into an issue that is new to me. If I try to update my system, either via command line or Discover, the apt update command fails. This is the output:
E: Could not get lock /var/lib/apt/lists/lock. It is held by process 1635 (apt-get)
N: Be aware that removing the lock file is not a solution and may break your system.
E: Unable to lock directory /var/lib/apt/lists/
Process 1635 is apt-get update run by root, and persists through restart. I am tempted to try to kill it (kill 1635), but I'm not sure if anything could break from that, so I thought I'd try to ask for help first before I do something stupid.
EDIT:
I have managed to update my system by killing the process, which releases the lock, and then going on to do normal sudo apt update and sudo apt upgrade. For the sake of troubleshooting, I tried to add back my third-party repos one by one, and none of them caused any problem. However, when rebooting the same issue as described above happens again. Software updates is set to "Manually" in the System settings.
In addition, everytime I ran sudo apt upgrade, at the end some update related to initramfs fails. My disk is encrypted using cryptsetup, and as I’ve come to understand, I should be very careful doing anything related to initramfs when that is the case. Here is the output:

EDIT 2:
The issue seems to have been narrowed down to a failure of Tuxedo's driver configuration service that runs at boot. It is this process that calls apt-get (and something I should've seen earlier...), and systemctl status reveals some errors:
aug. 08 15:33:56 laptop systemd[1]: Starting Tomte-daemon, finishes tasks that could not be accomplished before...
aug. 08 15:34:06 laptop tuxedo-tomte[1393]: no network found!! some fixes might not be applied correctly

I really appreciate the help from everyone so far. It's a good experience asking for help here, and I've learned a lot from your answers. Makes being a Linux newbie a lot easier. So thank you :)
Since this seems to be a very specific issue related to Tuxedo's own services, I will contact their support to get their input on what to do next.
I'm guessing Tuxedo's distro includes a service to automatically update the system or your repos on boot. It seems like the service is failing. I would take a look through your enabled services to see if you can find something related to updating, then you can check the status of the service for logs. You can also try asking Tuxedo support, who may have more insight into this problem.
Aha, that is exactly it! apt-get is called by their driver update tool, Tomte (https://www.tuxedocomputers.com/en/Infos/Help-Support/Frequently-asked-questions/What-is-TUXEDO-Tomte-.tuxedo). I actually would've seen this from the
ps auxf | lesscommand above if I had used my eyes a little better, as the top line in the output I pasted above is a sub-process running under Tomte.Checking
systemctl status tuxedo-tomte.serviceyields the following output:I guess contacting their support directly is the best way to solve this at this point.
Could you send the contents of the service file? It seems like the problem is that the service is running before the network is up and running. It might be resolved by setting the service to run after network-online.service
