  1. sudo snap remove pwgen-tyhicks

    From documentation:

    Prior to removal (except on Ubuntu Core systems), a snap’s internal user, system, and configuration data is saved as a snapshot (snapd 2.39+), and retained for 31 days. A snapshot can be used to restore the state of your snap upon reinstallation.

  2. Purge

    Use sudo snap remove --purge snapname to completely remove a snap package, including all of its revision loop drives. Only by doing so, will the hard drive space be made available again, as demonstrated below for the snap package firefox.

    $ lsblk
NAME     TYPE   SIZE    MODEL    SERIAL    WWN    MOUNTPOINT
…
loop6    loop  70.4M                              /snap/core22/275
loop7    loop 176.9M                              /snap/firefox/1810
loop8    loop 178.4M                              /snap/firefox/1860
loop9    loop 346.3M                              /snap/gnome-3-38-2004/115
…

    $ snap list
