A partir de alguns dias atrás, eu tenho este círculo vermelho com uma linha branca horizontal que persiste no painel no canto superior direito. Quando eu passar o mouse sobre ele, ele diz "Ocorreu um problema ao verificar as atualizações".
Quando houver atualizações para instalar, posso clicar duas vezes e clicar no botão 'instalar atualizações'. Há uma breve barra de progresso e nada acontece. Eu posso clicar com o botão direito do mouse no círculo vermelho e clicar em "insall all updates", e então ele diz "marcando" as atualizações com o gerenciador de pacotes synaptic e, em seguida, instala-as.
O círculo não vai embora e é apenas irritante. Não tenho certeza de como isso seria relacionado, mas desde que comecei, não consegui abrir o centro de software do Ubuntu. Quando vou aplicações > ubuntu software center, meu cursor apenas se transforma em um por alguns segundos, então nada acontece.
Qualquer ajuda é muito apreciada.

Parece que você não está usando o Python normal do sistema do maverick (já que o módulo CommandNotFound aparentemente desapareceu). Você instalou o Python a partir do código-fonte? Em caso afirmativo, tente sudo ln -sf python2.6 /usr/bin/python e sudo apt-get update novamente.
Abrir um terminal e sudo rm /var/cache/apt/*.bin , em seguida, sudo apt-get update && sudo apt-get upgrade devem resolver o problema.
Tente isto: link
