o centro de software não está carregando em 16.04 [duplicado]

Question

é muito bonito isso. Abrir o software center funciona com a guia 'todos' carregando bem, mas quando eu tento pesquisar qualquer coisa ou acessar qualquer outra guia, ele tem uma tela de carregamento eterna. Estou executando um ubuntu atualizado 16.04 em um computador de 64 bits, se isso ajuda.

Eu tentei a solução de problemas semelhantes em versões mais antigas do Ubuntu, mas elas não têm nenhum efeito.

quando eu executo o software center do terminal, recebo isso:

Answer 1

Você pode instalar o "Centro de software" clássico, que "sempre" funciona bem:

$ sudo apt-get update && sudo apt-get install synaptic

Answer 2

Há algo errado com seu arquivo de índice Xapian do APT:

2016-05-28 14:21:27,507 - softwarecenter.db.update - WARNING - failed to load file /var/lib/apt-xapian-index/cataloged_times.p: unsupported pickle protocol: 3

Mova-o para um arquivo diferente:

sudo mv /var/lib/apt-xapian-index/cataloged_times.p /var/lib/apt-xapian-index/cataloged_times.p.backup

Forçar uma reconstrução:

sudo update-apt-xapian-index -f
