I just updated to 18.04 from 16.04 and to 16.04 to 14.04 before that.
Anyway the 18.04 failed with an error saying something like gnome not installed and desktop depends on gnome. And it said it was going to recover, however it did nothing. After some time I restarted and the system. It came up with the desktop background but nothing else.
With Ctrl-Alt-F1 I am trying any commands I found without success.
Trying to install gnome I get missing dependencies. When trying to install
gnome-shell and have a dependency for
I installed libmutter-2-0 but gnome-shell still reports it as a missing dependency.
I also don't have gdm3 or seemingly any other parts of gnome.
I have no idea what I am doing, I have been searching and running commands for installing anything I can find, but so far no success.
I would like to get some gui working or go back to 16.04 if possible.
Edit 1 After N0rbert's advice:
sudo apt-get update sudo apt-get install ubuntu-desktop
Did something in the sense that I can see my a desktop, but I only see a login button the the account, which instantly fails even before I have a chance to enter my password. Here are some screenshots: login failed after click
Crash screen In previous version I had it not require a password to login so I am surprised it is asking for one. Is it possible I just need to reset the password or authentication system?
sudo apt-get update,
sudo apt-get install ubuntu-desktop.
sudo apt-get updatenow
sudo apt-get install ubuntu-desktopactually does something other than saying that there are missing dependencies. Not a single post mentioned
sudo apt-get updatebefore the other commands. Should I try to restart now?
sudo apt-get updateare launched periodically on its own. But for predictable results it is recommended to run it before installation of something. See this official documentation. If package installation is finished then you can reboot. The APT (package manager) is essential part of Debian and Ubuntu OS. You should learn it before use :)
sudo apt-get install gnome-coredid a lot of stuff, but overall it did not help. Then with more searching for login issue I found
dpkg-reconfigure lightdmthen i picked lightdm instead of gdm3 and after a restart I got the new desktop? Any ideas of what happened and anything else I might need to fix? Thanks again.
