App Center shows nothing but a black screen

Question

I installed Ubuntu 23.10 today, but the App Center won't display the software information, and it shows just a black screen. I installed it again after using sudo snap remove snap-store, but the problem still wasn't solved.

Answer 1

1. Refresh the App Center:

   Close the App Center and run the following commands.

   killall snap-store
   snap-store
   

2. Update the App Center:

   snap-store --quit
   sudo snap refresh snap-store --channel=latest/stable/ubuntu-23.10
   

   Leave the App Center open for about half an hour to give it time to download all the software packages' information.

3. Purge and reinstall the App Center:

   sudo apt update && sudo apt upgrade  
   sudo apt purge snap-store
   sudo apt install snap-store
   

   sudo apt purge snap-store removes App Center and its associated configuration files, and sudo apt install snap-store reinstalls them.
