[SOLVED] Help!!! I lost permissions to / :(

I was experimenting with commands in terminal and I was curious what will happen after command

sudo chmod o-x /

I lost permissions to everything... I rebooted pc and after grub screen there are "failed to start" errors. Can I return permissions?

... boot a live disk, mount the root partition, chmod it correctly again.

If you're messing around with commands that you try to understand do not apply them to a global location and most definitely do not sudo them. And maybe instead of randoming with commands read a bit of the underlying theory of what they are doing: https://wiki.archlinux.org/title/File_p … attributes

Try booting to the rescue target ( https://wiki.archlinux.org/title/Systemd#Targets ), or changing init to /bin/sh ( https://wiki.archlinux.org/title/Kernel … meter_list ). If all else fails, boot a liveCD and fix it there.
