ROOOTED!
User: Swagshop machine (root) prepared me about this (not exactly the same, but in my case I used the same page tutorial), so from data to user in no time!
Root: Once you get s*******l is the key for privileges escalation, just google how create something related… is really easy don’t overthink ! If for some reason you can’t enable it, change shell (it fixed in my case)
PM if you need help
