Typing sudo julia sounds like a wrong start.
Also, see that UpdateJulia.jl is effectively deprecated.
juliaup does not require sudo to update julia since only user folders are touched.

Yes, juliaup is currently the best option. It even can be easily used in servers for not requiring sudo access. I have used It in Windows and Linux systems without any problem.
