JuliaPro-1.5.3-1_build-142.sh does not run in my Linux Mint

I’ve previously worked with Julia using the Juno IDE on Windows.
I’ve migrated one laptop to Linux Mint and ensured devices and apps are up to date.
I have installed Julia and it runs in the terminal.

In following the steps to install Juno from JuliaPro I get no response to the following terminal command:
~$ chmod 777 JuliaPro-1.5.3-1_build-142.sh /home/red/Julia/

I realize that the problem may lie with linux, but any pointers would be appreciated.
