I am new with Ubuntu and after fresh installing Ubuntu 22.04 I noticed that I am not able to install any program via Ubuntu Software, then I installed the Software (gnome-software) and tried with it, but faced the same problem:

When I am opening the Software app and clicking on the any app to try install, after that the Software app closes automatically.

Then I tried to boot the Software app via terminal with the following command: gnome-software

And reproduce the same steps with choosing any app and after I clicking on the app the terminal shows errors below:

12:52:12:0966 Gs  Only 0 apps for recent list, hiding

Snapcraft, which Ubuntu Software uses in the background, is experiencing intermittent outages today due to a firewall issue on their part. You can see how it got HTTP 500 errors (server error) when trying to access api.snapcraft.io.

There is nothing you can do, since the issue is with their servers. It should be back up-and-running soon (hopefully).

Run the following commands:

rm ~/.local/share/gnome-software/*
sudo apt-get upgrade gnome-software
sudo apt-get update

This will solve the problem i hope.

Please comment if this worked for you.

  • Hello, thanks for your reply, but this does not help: rm ~/.local/share/gnome-software/* rm: cannot remove '/home/{user}/.local/share/gnome-software/*': No such file or directory, I already tried update & upgrade commands they did not help too...

  • Does gnome-software display apps?
