[Gambas-user] check 4 Gambas Runtime files?

Thu Dec 14 20:23:57 CET 2017

In Linux world things work via repositories and thus the newest version is
seldom available from them. So, the first question is, do you really
necessarily need newer, than the official repository version?
If you do, then you have to offer PPA for people using your software. You
could write script to uninstall possible old version, add PPA and finally
install latest Gambas. This way your customers do not have to do anything
else than give permission for the script.
Something like (start with the version detection given by Tobi):

sudo apt-get remove gambas3
sudo add-apt-repository ppa:gambas-team/gambas3
sudo apt-get update
sudo apt-get install gambas3

Quickly thinking that is the easiest way.
