So I finally decided to join my university Linux group, and has I been helping people with simple problems in discord for a while they put me in the helpdesk.

All fine and dandy, but other than dual boot and partitioning problems that I had to deal with myself (stupid laptop which does no follow efibootmgr order) I don’t know much about other kinds of troubleshooting.

Is there some reads or free online courses that u guys would recommende.
