Pois então, quando tento instalar qualquer coisa via Central de Programas do Ubuntu, o processo se inicia, mas logo depois mostra uma mensagem dizendo que eu não tenho permissão para instalar. E recentemente também tive alguns problemas de permissão de escrita em pastas do Gimp, sendo que instalei com o meu usuário, com privilégios suficientes. Fiquei com receio de ser um problema neste sentido, de permissões ou um nível de privilégio diminuído para o meu user, por algum motivo. Isso vem ocorrendo há 1 mês + ou -. Abaixo segue o resultado do terminal, com os comandos sugeridos (A priori, tenho trabalhado bem com comandos via terminal usando meu usuário):
sudo apte-get update
daniel@delinux:~$ sudo update
[sudo] password for daniel:
sudo: update: command not found
daniel@delinux:~$ sudo apt-get update
