I am using Ubuntu under WSL2. Yesterday morning, everything was fine and I did not do anything to the system. However, around evening, Juliaup could not find Julia any more. Actually, I was using the same screen in the morning.
julia
Command ‘julia’ not found, but can be installed with:
sudo snap install julia
I rebooted the system today but got the same error. I wonder what has happened.
Same problem here, using standard Ubuntu 24.04 without WSL. I deleted the .juliaup folder and reinstalled juliaup.
This solved the problem.
I believe this is a bug that has been fixed. IIUC, you can simply do juliaup self update and it should fix the bug.
By curiosity, what happened and how it went into without any apparent action by the user? (it happened to me as well, on Ubuntu)
Just found that ‘juliaup self update’ leaves a _postupdate process hanging up, holding lock to juliaup/julia config file (under Linux).
Killing this postupdate process get the lock freed with no apparent side effect. So hope everything is well now?
run “juliaup self update” - just because haven’t done it for long time. Now what I got:
Checking for new Julia versions
Checking for self-updates
Found new version 1.20.4 on channel release.
Juliaup configuration is locked by another process, waiting for it to unlock.
I’m on Mac, and actually it had been recently restarted and I haven’t done anything “julian” since.
Update: I’ve Ctrl/C the process after a while, and did other things (also running Julia). Now I wanted to see which juliaup version I actually have:
eben60@Mac ~ % juliaup --version
Juliaup 1.20.4
That is, update has been presumably performed, but then stalled at clean-up or whatever.
