Agreed, although OP has been pointed to this many times before (including on the last topic he opened, just a week ago, and over a year go initially) so I’ve given up on re-posting the link at this point…

Don’t do this, follow the Linux installation instructions instead:

If you’re on Manjaro, the best thing to do is install from the AUR. Go into Pacman, search for `julia-bin`, then install that. Make sure you have AUR support enabled. The version on Snap is broken.

I found [this video](https://www.youtube.com/watch?v=AJ3VJJZHiFA) on youtube helpful. Now i am able to open Julia by typing julia in CLI.
