Dependency problem installing The Gnome Desktop Environment

Please open a terminal (ctrl-alt-t) and isssue the following command

sudo apt-get install gnome gnome-core

Then select all output (edit - select all), copy it (edit - copy) and paste it into a new message of this question thread https://answers.launchpad.net/ubuntu/+question/198071

This is a Ubuntu 12.04 that has been recently upgraded from 11.04 via 11.10.

gnome-core is already the newest version.
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 gnome : Depends: evolution (>= 3.0) but it is not going to be installed
         Depends: evolution-plugins (>= 3.0) but 2.32.2-0ubuntu7 is to be installed
E: Unable to correct problems, you have held broken packages.

Apparently there are more dependency problems than just the one with gnome and gnome-core that has been described at the beginning.

Please try the following command:

sudo apt-get install --reinstall gnome gnome-core evolution evolution-plugins

If that command again ends with error messages, please execute the process that is described in https://help.ubuntu.com/community/PackageManagerTroubleshootingProcedure with the only exception that in step 6 you should not create a new question, but paste the output into a new message of this current question thread https://answers.launchpad.net/ubuntu/+question/198071

Things are going from bad to worse. apt now fully broken:

"Things are going from bad to worse. apt now fully broken:" This is not true, there is only a minor problem that for sure can be solved without much effort.

There was an error in one of the commands that you executed. Due to line-end truncating one of the commands got broken.
instead of
"apt-get install --reinstall gnome gnome-core evolution evolution-"
it should have been
"apt-get install --reinstall gnome gnome-core evolution evolution-plugins"
But it seems it did not do much harm.

Please open a terminal and issue the following commands:

sudo apt-get install --reinstall software-center
sudo apt-get -f install

and copy/paste all output into a new message of this question thread

Hi

I reinstalled software-center from a .deb, and evolution* as well. That seemed to be stuck at 2.3.
Gnome Desktop is now fully installed. A potential source of the problem may be the existence of two
versions of libebook:

$ dpkg -l | grep ebook
ii libebook-1.2-12 3.2.3-0ubuntu6 Client library for evolution address books
rc libebook1.2-10 2.32.2-0ubuntu2 Client library for evolution address books
rc libebook1.2-12 3.2.2-0ubuntu1~oneiric Client library for evolution address books
rc libebook1.2-9 2.30.3-2ubuntu2.1 Client library for evolution address books

$ dpkg -l | grep ecal
ii libecal-1.2-10 3.2.3-0ubuntu6 Client library for evolution calendars
rc libecal1.2-10 3.2.2-0ubuntu1~oneiric Client library for evolution calendars
rc libecal1.2-7 2.30.3-2ubuntu2.1

$ dpkg -l | grep dataserver
ii libedataserver-1.2-15 3.2.3-0ubuntu6 Utility library for evolution data servers
rc libedataserver1.2-11 2.28.3.1-0ubuntu5 Utility library for evolution data servers
rc libedataserver1.2-13 2.30.3-2ubuntu2.1 Utility library for evolution data servers
ii libedataserver1.2-14 2.32.2-0ubuntu2 Utility library for evolution data servers
rc libedataserver1.2-15 3.2.2-0ubuntu1~oneiric Utility library for evolution data servers

So there is a libebook minus 1.2 minus 12 and one without a dash between name and version.
If I run update-manager at the moment it wants to install libebook-1.2-12, libecal-1.2-10, libedataserver-1.2-15
although they are already installed. Weird. These are dependencies of evolution-plugins.

But things are working again now, so thanks for the assistance.

You have to be aware that by installing packages manually form a .deb file you have the potential to break dependencies in your package management system. So you should do that only as a last resort.

The output of dpkg -l grep "name" does not show that you have two versions of libebook installed. Only the lines that start with "ii" indicate installed packages. The lines with "rc" show packages that are not installed, but where some configuration files are left over. These usually do not create any problem and can be removed (e.g. by use of the synaptic package management program).

The only package that is double is libedataserver.
libedataserver1.2-14 most probably is a leftover from natty and most probably should be removed if there are not other packages depending on it.

Update-manager is right with respect to libebook-1.2-12 and others. You have 3.2.3-0ubuntu6 installed (the version that originally came with precise). Meanwhile 3.2.3-0ubuntu7 is available in precise-updates, solving a problem with adding events to Google Calendars. Even if you are not affected by that bug you should still allow the upgrade.

I recommend that you try the following:
Open a terminal and issue the following command:

apt-get --simulate upgrade

This command should tell what upgrade actions it wants to do (without really executing them).
