Howto free up space properly on my /var/lib/snapd filesystem when snapd is unavailable?

I'm using Ubuntu 20.04 LTS.

My snapd service is unavailable :

$ systemctl status snapd.service
● snapd.service - Snap Daemon
     Loaded: loaded (/lib/systemd/system/snapd.service; enabled; vendor preset: enabled)

Howto can I free up space properly on my /var/lib/snapd filesystem when snapd is unavailable ?

EDIT0 : Cannot start the snapd service successfully, maybe because my /var/lib/snapd filesystem is full.

  1. You can remove all unused version of snap packages. You can create script file and make it executable or just copy & paste it in the console.

    Note you need sudo rights for it.

    #!/bin/sh
LANG=en_US.UTF-8 snap list --all | awk '/disabled/{print $1, $3}' |
while read pkg revision; do
    sudo snap remove "$pkg" --revision="$revision"
done

    If the snap remove command does not work because the snapd server is not run, you should free some space manually. You can remove an old version of a snap package file.

    e.g. user ha two Chromium snaps, chromium_1781.snap and chromium_1801.snap. Just manually remove the older version using:

    sudo rm /var/lib/snapd/snaps/chromium_1781.snap

    And try to run the snapd service.

    Also you can clean you file logs to get free space by this command:

    journalctl --vacuum-size=100M

  2. Best Answer

    Run

    sudo rm /var/lib/snapd/cache/*

    to clear the cache, that should give you some free space.
