I hope this is the right place to ask.
I had a problem with PlayOnLinux and Internet research gave me the idea that the problem was with libz. I ended up installing libz from AUR over the Software GUI, which did not solve my problem. When I tried to remove libz again, it told me pacman would have to be removed too, which I obviously did not do.
Now I can not boot anymore. Everything is normal at first, but then when the login screen should appear I am stuck with a black screen.
How can I revert my actions and remove the AUR version of libz again and possibly restore the right version of libz again?
I can post every log files you need to see. I have access to my PC over Ubuntu that I have installed besides Antergos and I don’t know how to obtain the journalctl log over Ubuntu.
The solution might be fairly easy, but I don’t want to make it worse, that’s why I am bothering this forum.
Any help is greatly appreciated.
