Trying to remove gnome3-no joy!

[selittl]

I installed gnome 3 to test it out, now I can't remove or purge it. I am running LM13 RC with MDM installed. When I try to remove I get the following:

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
gnome-core : Depends: gdm (>= 3.0) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Anyone now how I can get rid of it? I tried

Code: Select all

sudo apt-get -f install

and no joy there either.

a little more info. I think there is a gdm/mdm conflict. Upon trying to install gdm I get the following:

I seem to have a similar problem. I'm trying to install Nvidia drivers with no luck so far. There is another thread here with a solution to install gdm as default while keeping mdm and/or lightdm etc. driver install went smoothly for that poster. I thought I would try the same but came up with the trying to overwrite .......nobody.png and broken pipe . That is being brief. I will gladly paste all the contents of a text file I have been updating on this subject if that would be helpful.

Basically I want to install gdm while leaving mdm intact and proceed with driver install. possible?

Bump. Did you ever find a solution to this? I tried to install the gnome package and ran into this packaging bug. Now I can't install or uninstall anything, and I don't know how to resolve it.

[kjkrum]

It seems silly to have them conflict over an image resource. Or are there more files that conflict, but it only reports the first one?

What if I use --force-yes to complete the installation of gdm? I just want to try gnome3.

[kjkrum]

Hmm. Would it be reasonable to suggest that MDM should satisfy a requirement for GDM? Can I alter my own package database so that it does, at least temporarily? (This is taking a new direction, maybe I should start a new thread...)

BTW...

apt-get remove --purge gnome-core?

Code: Select all

kevin@freyja ~ $ sudo apt-get remove --purge gnome-core

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 gnome : Depends: gnome-core (= 1:3.0+6ubuntu3) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Still haven't found a way out of this mess.
