sudo chmod 000 -R /is very fun way of braking your system and is not widely known ๐What does this do? nobody can read any file? would sudo chmod 777 fix it at least to a usable system?
Yep. You could run chmod again to fix it (from a different OS / rescue USB), but that would leave all the permissions in a messy state - having everything set to 777 is incredibly insecure, and will also likely break many apps/scripts that expect more restrictive permissions. So the only way to fix this properly would be to reinstall your OS/restore from backups.
