When I try to start Julia I get the message:

```julia
Juliaup configuration is locked by another process, waiting for it to unlock.

```

and than it hangs, nothing else happens.

In the past I also saw this message, but it disappeared usually after less than a second. Now hangs at this state for a long time (\> 20s).

What could be the reason?  
How to fix?

This happens with and without the usage of VSCode on Ubuntu 24.04 and Julia 0.10.5.

Problem disappeared. `juliaup update` works, and the hanging also disappeared.

But there seams to be a bug in `juliaup` that it hangs when some server is not available.
