Eu procurei por isso, mas não encontrei nenhuma referência a ele neste site. Se você conhece algum, por favor, me encaminhe para ele - os problemas que tenho visto têm sintomas diferentes. Então, ao ponto ...
Eu tive o Ubuntu 12.04 LTS por um longo tempo, mudei para o Ubuntu Gnome Shell etc. Recentemente eu queria mudar para o Ubuntu 13.04 e descobri um problema que aparentemente ocorria anteriormente, mas a uma taxa aparentemente aleatória. Agora não consigo iniciar o Ubuntu Software Center.
Quando eu executo o console, vejo:
$ software-center
(process:22270): Gtk-WARNING **: Locale not supported by C library.
Using the fallback 'C' locale.
Traceback (most recent call last):

Eu esperava que seguir essas ideias ( fonte ) pudesse ser útil:

$ sudo apt-get update
$ sudo apt-get dist-upgrade
$ sudo apt-get install software-center
$ sudo dpkg-reconfigure software-center --force

O que estou fazendo de errado? Como posso me livrar do Ubuntu Software Center causando erro e instalar a versão que não terá isso?
Ou talvez o problema esteja no meu interpretador Python?
$ python --version
Python 2.7.3
Acredito que o Ubuntu está gradualmente se movendo para ferramentas que trabalham apenas no Python 3.x, mas essa é a causa?
Obrigado por todas as dicas. Eu acredito strongmente que também pode ser útil para os outros.
Atualização 1:
A primeira atualização foi de 12.04 para 12.10, e eu não percebi que não chegou a 13.04. Assim que percebi, atualizei de 12,10 para 13,04. O problema, no entanto, não desapareceu.
Eu também fiz perguntou :

Aparentemente, erros relacionados a localidade desapareceram, mas ainda não consigo executar o Ubuntu Software Center, mesmo depois de tentar reinstalá-lo.
