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.

apt-get remove --purge gnome-core?

And yes. gdm and mdm do conflict. They are now officially claimed to conflict:
https://github.com/linuxmint/mdm/commit ... 21587e350f

[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.

[dalcde]

The conflict over the image is probably not intended, but they do conflict in other places. Mdm has to "pretend" to be gdm because gnome screensaver only recognizes gdm but not mdm. With mdm "pretending" to be gdm, we must remove gdm.

[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...)

[kjkrum]

BTW...

apt-get remove --purge gnome-core?

Code: Select all

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.
