Hello,
I have installed Zentyal 4.2 64bit into a Virtualbox. It's a fresh install.
I am informed that 61 system updates are available.
I click on "update"!
It fails with "apt-get install failed.... blablah ... -fix-missing?"
Now I guess I have to edit /etc/apt/sources.list but I don't know from where to get the "good" updates.....
Also, GCC C-Compiler is not pre-installed, which is a shame. I need to compile....!
