Eu tive o mesmo problema, mas está funcionando novamente agora.
Foi corrigido nesta atualização que consegui instalar hoje:
Quando tento executar o QGIS, recebo os seguintes erros na inicialização:
An error occured during execution of following code:
import pyplugin_installer
Traceback (most recent call last):

Depois disso, o QGIS é iniciado. Eu então recebo uma mensagem de erro semelhante quando tento abrir o console do Python ou o menu de plugins.
Eu tentei apt-get purge qgis e, em seguida, reinstalei-o com apt-get install qgis -f . Mas recebo as seguintes mensagens de erro ao tentar limpar / instalar:

No apport report written because the error message indicates its a followup error from a previous failure.

Obviamente, o problema parece relacionado ao Python, mas não consigo descobrir como diagnosticar o que está errado aqui. Alguém tem alguma idéia sobre como consertar isso, ou idéias sobre outros lugares para procurar pistas sobre o que está acontecendo? Obrigado.
