Bug#794790: gnome-shell: unmet dependencies against evolution-data-server (>= 3.7.90) and gnome-contacts

[Roy Sindre Norangshol]

Source: gnome-shell
Severity: important

Dear Maintainer,

After a apt-get dist-upgrade I was too quickly disposing of gnome-shell when upgrading my system.
After trying apt-get install gnome-shell afterwards it tells me that it has unmet dependencies.

The following packages have unmet dependencies:
 gnome-shell : Depends: evolution-data-server (>= 3.7.90) but it is not going to be installed
               Recommends: gnome-contacts but it is not going to be installed

It might be a problem with libphonenumber6 which is one of it's transitive dependencies which
 requires liboost-date-time.155.0

>  apt-get install gnome-shell libphonenumber6 libboost-date-time1.55.0 libstdc++6

norangshol at bluebox:~$ sudo apt-get install gnome-shell libphonenumber6 libboost-date-time1.55.0 libstdc++6

I wish to be able to install the gnome-shell package again.


If this is a silly user error due to silly apt-get dist-upgrade, please ignore this bug report and slam me. :'(
