Ubuntu - 我无法启动应用程序并使用 sudo 运行命令

Question

I am writing this post because after several hours of research I did not manage to find an answer.

I have been using Ubuntu 20.04 for a few months in dualboot on my original Windows. But since a few days I have not been able to launch applications (example: Chromium, Firefox, Visual Studio Code, Settings), I tried to launch them via the terminal, but I have no response, not even an error. I also cannot execute a command with sudo

After several searches I understood that it could come from gnome, I then try several subject recommend it to execute

$ killall gnome-control-center
$ gnome-control-center

When I try to kill I get no response, and when I run gnome-control-center I get the following error: Failed to register: Timeout was reached

I cannot move forward in my plans because of this problem, would you have a solution please?

Answer 1

This might just be that something on your system is corrupted, you might just have to copy the files you use all the time (Code, pdfs) wipe the drive and reinstall your ubuntu. Also, check if the Windows is working if that's not working it might be a problem with your computers internals.
