When I type:

$ mount|grep snap
/var/lib/snapd/snaps/ubuntu-core_352.snap on /snap/ubuntu-core/352 type squashfs (ro,relatime)
/var/lib/snapd/snaps/ubuntu-core_423.snap on /snap/ubuntu-core/423 type squashfs (ro,relatime)
/var/lib/snapd/snaps/ubuntu-core_122.snap on /snap/ubuntu-core/122 type squashfs (ro,relatime)

I see several old snap "mounted" and available while only the latest version is used as current in /snap/ubuntu-core

It's not a big deal but do I need older ubuntu core ? Isn't this a bug there are not deleted ? Could I simply unmount and delete the files ?

  sudo snap remove core --revision 122
  sudo snap remove core --revision 352

So, basically passing the revisions to remove in the command line.

To check the ones you've installed you have to use snap list [snap-name] --all

    Considering current package name, up to date command looks like: sudo snap remove core --revision 122 – dess Mar 13 '17 at 15:17

    snap list --all to list installed packages with all revisions. Check also how to remove all disabled snap packages. – Pablo A Sep 8 '18 at 18:49

This is done, so you can snap revert to rollback to an older snap version.

So I unmount the old snap:

sudo umount /snap/ubuntu-core/122

and then done some manual clean up

sudo rmdir /snap/ubuntu-core/122
sudo rm /var/lib/snapd/snaps/ubuntu-core_122.snap

The same for the other one. The sky did not fall... yet

  • In my case, the last command sudo rm /var/lib/snapd/snaps/ubuntu-core_122.snap was non necessary. – Serge Stroobandt Oct 21 '17 at 15:22
  • gist.github.com/tsbertalan/f49f892a58d2a0889358e5b6b64af028 Here's a gist that automates this for multiple mounts. It doesn't actually run its commands; just prints what you would run, which is easy enough to change. – tsbertalan Nov 24 '18 at 18:58
  • yout script removes all the snaps. This is not what you want ! – solsTiCe Nov 24 '18 at 19:19
  • sudo: unmount: command not found .... ? – Rabbit May 16 at 16:40
