I am using ubuntu 16.04. I downloaded JuliaPro from website. Following the steps, I ran
$ ./Launch_JuliaPro
bash: ./Launch_JuliaPro: Permission denied
so, I added sudo
I agree with @Tamas_Papp.
If you really prefer, try accommodating the error message.
perhaps sudo ./Launch_JuliaPro --no-sandbox
would work (I do not have Ubuntu running).
