Не удалось обновить xserver-xorg-core. Не полностью установлен или удален

Я пытался обновить xserver, загрузив xserver-xorg-core_1.14.5-1ubuntu2_amd64.deb с packages.ubuntu.com , и когда я попытался установить его, он сказал:

(Reading database ... 266118 files and directories currently installed.)
Preparing to replace xserver-xorg-core 2:1.14.4.901+git20131203+server-1.14-branch.c30db601-0ubuntu0sarvatt4 (using xserver-xorg-core_1.14.5-1ubuntu2_amd64.deb) ...

dpkg: dependency problems prevent configuration of xserver-xorg-core:

dpkg: error processing xserver-xorg-core (--install):

Теперь всякий раз, когда я пытаюсь обновить или установить что-то, что говорит:

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 xserver-xorg-core : Depends: xserver-common (>= 2:1.14.5-1ubuntu2) but 2:1.14.4.901+git20131203+server-1.14-branch.c30db601-0ubuntu0sarvatt4 is to be installed
                     Depends: libgcrypt11 (>= 1.5.1) but 1.5.0-3ubuntu3 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Когда я делаю sudo apt-get -f install, он говорит:
