I had problems during the execution of install_juliapro.sh. So I looked inside the script and found some clauses, scanning an output for the pattern “installed” while checking the pre-requisites. The problem is, that the output depends on the systems language and the script wouldn’t identify the pre-requisites as installed when the output is not in english. My solution was to change the clauses in lines 69 and 71, replacing “installed” with the corresponding word in my systems language, “installiert” (german).
I hope this is helpful for other people.
