Change Sources.List , could it cause problems?
I needed a newer version of fail2ban, the one in the DO sources is 8.1 and the latest version is 9.1.
Tried to install fail2ban 9.1 manually, but it has loads of dependencies not in the DO sources.
I added “deb http://xx.archive.ubuntu.com/ubuntu vivid main universe” to the sources list and a lot of new stuff was installed....
And fail2ban is now working as it should. Don’t know yet if I broke other things, but everything seems fine.
Now before I change sources templates etc, does changing the sources to other than de DO ones, cause any problems??
