Falha na desinstalação do Octave no Ubuntu 12.04 (problemas ao reinstalar o Octave)

Question

Eu sou um Ubuntunovato, por favor tenha paciencia comigo.

Ao tentar desinstalar o octave-3.2.4, acabei fazendorm-rfem todos os diretórios e arquivos relacionados à oitava em/usr/bin/antes de poder instalar a versão mais recente do GNU Octave. Ao tentar instalar o Octave agora, estou recebendo o seguinte erro, com o qual preciso de ajuda para resolver:

The following packages have unmet dependencies:  
octave : 

Depends: libarpack2 (>= 2.1) but it is not going to be installed  
      Depends: libfftw3-3 but it is not installable  
      Depends: liboctave3 (= 4.0.0-3ubuntu2~octave~precise5) but it is   not going to be installed  
      Depends: libqscintilla2-8 but it is not installable  
      Depends: default-jre-headless but it is not installable  
      Recommends: pstoedit but it is not installable  
E: Unable to correct problems, you have held broken packages.

tar -xvf octave-3.8.0.tar.bz2
cd octave-3.8.0

Answer 1

Todos os pacotes ausentes estão no repositório principal, portanto

sudo apt-add-repository main
sudo apt-get update

E multiversetambém é uma boa ideia

sudo apt-add-repository multiverse
sudo apt-get update

Se sudo apt-add-repository maine sudo apt-add-repository multiversenão funcionar, faça o seguinte

1. sudo mv /etc/apt/sources.list /etc/apt/sources.list.bak
2. AbrirSoftware & Updates

3. Ative as entradas para maineuniversemultiverse

   

4. CliqueClose

5. Atualize as fontes do pacote viaReload
