Today I decided it would be a good idea to upgrade my webhost service and php. Alas I commited a capital sin by not doing any backups and expecting everything to go smoothly.
My distro stopped going into gui. I was locked in the console. Any attempts to initiate it resulted in a black screen. Things were looking grim.
After hours of trial and error, success! We got back into the distro and fixed all issues with the services.
TLDR: Always backup your data before doing upgrades to avoid making rookie mistakes!
