Não é possível instalar programas no Ubuntu 14.04

Question

Eu recebo este pop-up toda vez que tento baixar algum programa on-line!

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.

Details

The following packages have unmet dependencies:

vlc: Depends: vlc-nox (= 2.1.6-0ubuntu14.04.1) but 2.1.6-0ubuntu14.04.1 is to be installed
     Depends: libc6 (>= 2.15) but 2.19-0ubuntu6.6 is to be installed
     Depends: libfreetype6 (>= 2.2.1) but 2.5.2-1ubuntu2.5 is to be installed
     Depends: libgcc1 (>= 1:4.1.1) but 1:4.9.1-0ubuntu1 is to be installed
     Depends: libqtcore4 (>= 4:4.8.0) but 4:4.8.5+git192-g085f851+dfsg-2ubuntu4.1 is to be installed
     Depends: libqtgui4 (>= 4:4.8.0) but 4:4.8.5+git192-g085f851+dfsg-2ubuntu4.1 is to be installed
     Depends: libsdl-image1.2 (>= 1.2.10) but it is not going to be installed
     Depends: libstdc++6 (>= 4.6) but 4.8.4-2ubuntu1~14.04 is to be installed
     Depends: libva-x11-1 (> 1.3.0~) but it is not going to be installed
     Depends: libva1 (> 1.3.0~) but it is not going to be installed

Answer 1

Supondo que você esteja tentando instalar usando o comando dpkg --install , use o gdebi.

Primeiro , você precisa baixar o gdebi usando este comando:

sudo apt-get install gdebi

Próximo , você precisará usar o gdebi para instalar o arquivo .deb:

sudo gdebi whateverfilehere.deb

Funciona para mim como um encanto. Boa sorte!

PS: solução alternativa
Você também pode tentar instalar os pacotes ausentes manualmente, como:

sudo apt-get install vlc-nox
sudo apt-get install libc6
sudo apt-get install libfreetype6
...
