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:

Processing triggers for initramfs-tools (0.140ubuntu13.2) ...

I: The initramfs will attempt to resume from /dev/dm-2

Errors were encountered while processing:

E: Sub-process /usr/bin/dpkg returned an error code (1)

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
aug. 08 15:34:06 laptop tuxedo-tomte[1393]: systemctlCmd: systemd-run --on-active="30sec" tuxedo-tomte configure all >/dev/null 2>&1

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 haven’t used Tuxedo, but on apt-based distros it’s pretty common for an auto-update daemon of some kind to run in the background on startup to either download updates, or at least download package metadata so some UI component can start nagging you to install the updates that are available.

    If you wait a few minutes, the download should complete and you can do what you want. You can probably get away with killing it, especially if you use a gentle signal like HUP. I wouldn’t risk it though… if you corrupt your package metadata or worse… and actual important package… it can be a significant hassle to clean up the mess. And the cost of waiting 30s-5m and trying again is so low it’s hard to beat that as an approach.

    If its happening a ton you can probably find and disable the auto-update thing but I don’t know what it would be on Tuxedo.

      It persists even after several hours. Never happened before, and I’ve been using the system for about 6 months now. I posted the output from the process tree below, but I’m not sure if that makes anything any clearer. It’s as if it is not receiving any data and just waiting for the servers to respond?
