I can confirm this bug in Ubuntu 12.04.2 LTS (originally 12.04.1, then upgraded to Quantal HWE). The workaround in #2 worked for me but during installation I encountered some errors which had the following form:
... ERRORS: clementine depends on libgl1-mesa-glx | libgl1; however: Package libgl1-mesa-glx is not installed. Package libgl1-mesa-glx-lts-quantal:i386 which provides libgl1-mesa-glx is not installed. Package libgl1-mesa-glx-lts-quantal which provides libgl1-mesa-glx is to be removed. Package libgl1 is not installed. Package libgl1-mesa-glx-lts-quantal:i386 which provides libgl1 is not installed. Package libgl1-mesa-glx-lts-quantal which provides libgl1 is to be removed. compiz-plugins-main-default depends on libgl1-mesa-glx | libgl1; however: Package libgl1-mesa-glx is not installed.

Fortunately when the installation completed these dependency were resolved on their own. This is the second time I encounter serious dependency issues while trying to install a hardware enablement stack. (previous issue: https://bugs.launchpad.net/ubuntu/+source/xorg-lts- quantal/+bug/1125413). I sincerely hope that these problems will be fixed by the next HWE release cycle. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-lts-raring in Ubuntu. https://bugs.launchpad.net/bugs/1191563 Title: xserver-xorg-lts-raring cannot be installed due to unresolvable dependencies To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-lts-raring/+bug/1191563/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
