I recently installed Ubuntu 20.04.
I attempted to install apps from the Ubuntu software center, but it isn't working correctly.

  1. No icons are displayed. https://ibb.co/Rc4BmF0

  2. No screenshots or information about the applications are displayed. https://ibb.co/GRWCmQm

I tried Ubuntu Software not loading properly but it didn't work.
How to fix?

  • Try this; HOLD CTRL+ALT and hit T - this should normally open a Terminal (with Bash prompting for commands). Type dmesg | less and then hit > to make "less" go to the very end of the text... now scan backwards (cursor up, page up) and look for "error", "failed" and similar... if you find any then edit your posting above and add the information there. This will help readers here analyze what the actual problem is. NOTE: You might need to actually run "Ubuntu Software" at least once to see any errors. – Hannu Jan 09 '22 at 09:17
  • there isn't any error message about snap-store or ubuntu store only errors like (device not accepting address 10, error -71) but there are a lot of snap-store message. should I copy paste those? – Bimal Pandey Jan 09 '22 at 09:58
  • The snap-store messages might contain a clue; "Ubuntu software" does have a "close" snap store relation. Include the text and make it be "code" (mark text, click {}) – Hannu Jan 09 '22 at 10:09
  • I've updated them, most of them are similar to the ones above – Bimal Pandey Jan 09 '22 at 10:25
  • You might have found the culprit; I'm not sure how to fix it though, somone who knows more about snap / apparmor needs to see this. – Hannu Jan 09 '22 at 10:28

This issue has existed for a long time. Ubuntu's Snap store isn't well-maintained and doesn't perform properly. As a result, in Jammy 22.04, they've chosen to use Gnome software instead. Gnome software is working fine without any issues. You can install gnome-software using:

$ sudo apt install gnome-software

If you want to remove the Ubuntu software app:

$ sudo snap remove snap-store

Gnome software is way better than the default application centre. The user interface is nearly the same.

Note: Ubuntu Snap Store is a re-designed version of Gnome-Software but unfortunately with bugs.

You can launch gnome software using:

 $ gnome-software

You can also launch it using the application overview.

Here is how it looks like:

Gnome software Icon

Here is the UI of Gnome Software in Ubuntu 21.10:

You can install additional plugins for it too. For example, you can run the following command to enable the snap plugin in Gnome Software:

$ sudo apt install gnome-software-plugin-snap

If you want to enable flatpak support then you can run:

$ sudo apt install gnome-software-plugin-flatpak
