Невстреченные зависимости с Кв. - добираются, стандартные решения, не работающие

Я работаю 14.04LTS. Кв. - начинает бросать ошибки о невстреченных зависимостях. Я сделал довольно мало поиска и устранения неисправностей и все общие решения такой как sudo apt-get install -f и sudo dpkg -a --config не работают.

Как обычно, я работаю sudo apt-get update который, кажется, работает.

Я не могу установить зависимости или установить способность, потому что любое использование Кв. - добирается, возвращает следующие ошибки:

$ sudo apt-get install aptitude

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 aptitude : Depends: libboost-iostreams1.46.1 (>= 1.46.1-1) but it is not going to be installed
            Depends: libcwidget3 but it is not going to be installed
            Recommends: libparse-debianchangelog-perl but it is not going to be installed
 libgl1-mesa-glx-lts-trusty : Depends: libglapi-mesa-lts-trusty (= 10.1.3-0ubuntu0.2~precise2) but it is not going to be installed
                              Recommends: libgl1-mesa-dri-lts-trusty (>= 7.2) but it is not going to be installed
 xserver-xorg-video-vmware-lts-trusty : Depends: libxatracker2-lts-trusty but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Затем фиксация не работает:

$ sudo apt-get -f install

Я вижу, что существует ошибка:

xz: /usr/lib/x86_64-linux-gnu/liblzma.so.5: version `XZ_5.2' not found (required by xz)

но когда я ищу его:

$ sudo find / -name liblzma.so.5
