Question

Quando eu faço sudo apt-get update

Recebo erros de acompanhamento:

E: Some index files failed to download. They have been ignored, or old ones used instead.

Eu suspeito que isso está me causando muitos problemas ao adicionar novos ppa e instalar outros programas. No momento eu não consigo instalar o rmagick gem, que requer outros pacotes que não serão instalados porque diz:

The following packages have unmet dependencies:
 libmagickcore-dev : Depends: librsvg2-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Por favor, ajude, ou o último recurso será a reinstalação do Ubuntu, que eu tenho certeza que ninguém gosta.

Após sua informação, a saída de lsb_release -a é

Para corrigir isso, execute estes comandos:
