Can't run lutris ( need help )

Hello , I’ve just installed Lutris on Linux Mint 19.1 Cinnamon , but I can’t run it unless I run it with sudo . it has something to do with permissions . like this :

Traceback (most recent call last):
File “/usr/bin/lutris”, line 31, in
from lutris.gui.application import Application

return open(self.baseFilename, self.mode, encoding=self.encoding)
PermissionError: [Errno 13] Permission denied: ‘/home/archer/.cache/lutris/lutris.log’

I really don’t want to reinstall linux again to make it work .

Did you start lutris as super user? If so it could well be that lutris created files and set the owner to root. Files owned by root can’t be accessed by an account lower than that. Even if these reside in your home directory.

You can find out the owner of file by using this command:

ls -la /home/archer/.cache/lutris

If the owner is root you can change this by using this command:

sudo chown -R archer /home/archer/.cache/lutris

Hope this helps.
