Amigos,
Dias atrás tive problemas de atualizacão no PCLinuxOS LXDE BR, mas entrando como root e com a ajuda do Ag. Smith, consegui resolver o problema.

Agora é no KDE 64 bits que estou travado. A última atualizacão não ficou 100% e nao consigo fazer coisas no terminal de root porque o usuário nao tem mais privilégios, e o root nao consegue também resolver! A atualizacao ficou incompleta??? O ícone de desktop na barra sumiu e tenho um X branco em um quadrado vermelho, no lugar dele.
No terminal, recebo isto (ver abaixo).
ALGUMA SUGESTAO??

[root@localhost ~]# apt-get upgrade

Talvez seja a falta da seção special.

Depois de apanhar, reiniciar e demais, atualizei tudo o que pude.
O problema era que nem como root conseguia "desbloquear" o sistema de atualização. Na verdade nem sei como, mas consegui contornar isso, fazer o update e o upgrade e o laptop funciona! (estou escrevendo desde ele).

Abraços!

E, como a sua distro é a versão americana, não esqueça de setar os repositórios para apontar para a UFPR, que as versões estrangeiras não vêm com o repo Brasileiro setado por default.
