minus-square@bitchkat@lemmy.worldlinkfedilinkEnglish53•5 days agoHad an idiot “fix” a permission problem by running “sudo chmod -R 777 /” And that is why sudo privileges were removed for the vast majority of people.
minus-square@bigbuckalex@lemmy.ziplinkfedilink18•5 days agoOh… That sounds like a nightmare. How do you even fix that? There’s no “revert the entire filesystem’s permissions to default” button that I’m aware of
minus-square@justme@lemmy.dbzer0.comlinkfedilink8•5 days agoIf you are lucky your system is atomic or has other roll back feature. Otherwise it’s reinstall time. I guess you could set up a fresh system, run a script that goes through each folder checking the permission and setting it on the target system.

minus-square@mlg@lemmy.worldlinkfedilinkEnglish7•4 days agoShared this before, but someone I know did a chmod on /bin which nuked all the SUID/GUID bits which borked the system lol. Surpsingly easy enough to undo by getting a list of the correct perms from a working system, but hilarious nonetheless

You restore the system from backup
