Ubuntu – Problem with installing GNOME Shell: unmet dependencies

11.10dependenciesgnomeinstallation

When I tried to install GNOME Shell (using Ubuntu Software Center) this error showed up.

Error message

The message says:

Package dependencies cannot be resolved

This error could be caused by required additional software packages which are missing or not installable. Furthermore there could be a conflict between software packages which are not allowed to be installed at the same time.

Here the dependencies:

The following packages have unmet dependencies:

gnome-shell: Depends: libpulse-mainloop-glib0 (>= 1:0.99.1) but 1:1.0-0ubuntu3 is to be installed
             Depends: libpulse0 (>= 1:0.99.1) but 1:1.0-0ubuntu3 is to be installed
             Depends: libxfixes3 (>= 1:5.0) but 1:5.0-4 is to be installed

So can you help me install GNOME Shell?

Best Answer

I had similar problem with gnome-session-fallback instalation. The problem seems to be because you try to install something that depends on old versions of

libpulse-mainloop-glib0, libpulse0 and libxfixes3

. Try to uninstall those three and then install the gnome shell. The dependencies should get installed in older versions as a result.

Ubuntu – Cannot download softwares from the Software Center

There might be updates pending that need to be installed before installing software. Make sure that your software sources are updated.

To update your system press Alt+F2 while in your desktop and look for update-manager

Press Check and after it is finished press Install Updates.

Has an option you can open a terminal and do the same with sudo apt-get update && sudo apt-get upgrade. This is preferable since if you get any errors you can copy them and include them in your question.

To open a terminal just press the keys Ctrl+t while in your desktop.

Reboot to be sure and try to install the software again.

Steam Installation – How to Resolve 64-bit Package Dependencies

steam64 is just a virtual package for the i386 steam package of the same version.

By default, x64 Wubi (and normal?) installs don't have i386 support enabled, which is required by the steam package. To enable it, you can do this at a terminal:

sudo dpkg --add-architecture i386
sudo apt-get update

As of this writing, the steam and steam64 debs in the software center are out of date (1.0.0.26) and contain Beta warnings. These warnings have been removed in the .deb on the Steam site (1.0.0.27).
