Por que estou recebendo este erro ao atualizar após uma atualização parcial?

Question

Fui solicitado por uma atualização parcial e concluí-a. Durante isso, o VLC foi removido. Quando tento reinstalar, obtenho isto:

isuru@isuru-desktop:~$ sudo apt-get install vlc

Answer 2

Abra uma corrida no terminal

sudo apt-get update && sudo apt-get dist-upgrade

Quando isso estiver concluído, abra o centro de software, digite vlc no campo de pesquisa e siga as etapas restantes como faria normalmente.
