How do I solve this error on Ubuntu Hirsute Hippo (21.04)?

Unable to update "Core 18": snap has no updates available"

Screenshot of Error Updating Core 18

It's already installed as I check with the terminal:

    sudo snap install core18

snap "core18" is already installed, see 'snap help refresh'

I also try snap refresh


    sudo snap refresh
    All snaps up to date.

and I try with Ubuntu Software again and can't update it.

and I can't remove it as I use it by chromium and Libre Office


    sudo snap remove core18

error: cannot remove "core18": snap "core18" is not removable: snap is being
       used by snaps chromium, gnome-3-28-1804, gnome-3-34-1804,
       gtk-common-themes, libreoffice and 1 more.

when I try to refresh it on the terminal, no update.

sudo snap refresh core18
snap "core18" has no updates available

I belive this maybe a bug with Ubuntu Software

It seems 20.04 was hit with this as well. Maybe the bug filtered itself into 21.04 as well?

  • Yes, it's installed, I check the link, but not solved, still showing up and I try the terminal and find it's installed already, but not able to update it. – Sharif May 18 '21 at 01:55
  • Try sudo snap resfresh core18. Also, snaps are a tad funny. Some people get the new updates earlier than others when they are first released. A "progressive" release so to speak. Since 21.04 "hit the market" only a short time ago, this may also be the issue.

    In either case, Core18 will stay there if needed by snaps built on 18. If you have no snap currently using core18, it's safe to uninstall it.

I would recommend to purge Snapd completely in four steps:

  1. Save the list of installed snaps by running

    snap list

  2. Purge snapd

    sudo apt-get autopurge snapd

  3. Reinstall Snap

    sudo apt-get install snapd

  4. Reinstall snaps using list from no. 1
