You'll only understand my question if you have used Windows and Windows repair disk before. That disc repairs everything automatically, almost no command line, no debugging, nothing. You just create the disk, and if you ever messed up your system, it repairs everything automatically.

On the Linux side, we have boot repair disk, which is awesome but it repairs grub only.

Lets say I messed up my Desktop environment, or something, is there there a tool to check what I needs to be fixed and fix it automatically.

I'm asking this question because I encounter so many issues and it would be nice if there's an automated way to fix them.
