Before upgrading on new version BACKUP ALL DATA!!!

I upgraded to Ubuntu 24.04 (from Ubuntu 22.04).

After rebooting and login on my account I saw white background with message "Oh no! Something went wrong!". I tried to Log out, but it was not successful.

Solutions I read included next steps:

1. Before Log out, press next CTRL+ALT+F3. Login with your credentials and password.

2. Execute commands (of your wifi is disabled, then plug-in cable)

   sudo apt-get update && sudo apt-get upgrade
   
   sudo dpkg --configure -a
   
   sudo apt-get clean && sudo apt-get autoremove 
   
   sudo reboot 
   

If these steps doesn't resolve your problem, then execute these commands. Use again CTRL+ALT+F3

    sudo apt --fix-broken install

    sudo dpkg --configure -a 

    sudo apt-get update

    sudo reboot 

This solution worked for me in error message "Oh no!Something get wrong."

Did you have other errors in upgrading on Ubuntu 24.04? How did you resolved problems?

If this was helpful share it with others to help each other.

TIP Additional which worked for others is command:

   sudo apt reinstall ubuntu-desktop
