How do I uninstall Zentyal or can I revert to a 'clean' installation somehow?

Question

I have installed zentyal 3.5 from the Zentyal PPA on a fresh ubuntu 14.04 installation. After a few tests I want to uninstall zentyal. Unfortunately, there are no instructions as to how to remove it.

What I did to remove the software was this: I removed the zentyal PPA and ran sudo apt-get remove zentyal-* But now, network manager doesn't work any more, and my system doesn't get DHCP assigned addresses.

How can I revert to a 'fresh' 14.04 installation to completely remove Zentyal?

Solution

Never use the remove command with packageName ended with *, as it will possibly damage your system or erase other packages' requirements.

Run sudo apt-get purge zentyal to remove the installed zentyal package, and then run sudo apt-get update and sudo apt-get upgrade.

It should fix the problem.
