Note que eu estou correndo um 8GB USB com 4gb persistência habilitado, não é por isso porque ontem eu tinha tudo configurado e trabalhando com tudo o download corretamente, então eu fiz uma nova conta de usuário e depois de definir nenhuma senha para ficava me pedindo a senha, então eu formatei meu usb novamente e voltei para o primeiro passo:)
eu tenho Ubuntu trabalhando, eu posso instalar a partir do centro de software, mesmo que eu recebo um código de erro ainda instala :) Estou tentando instalar o Ubuntu tweak e canela via terminal e me disseram que eu faço isso digitando isso em um terminal:
sudo add-apt-repository ppa:tualatrix/ppa
sudo apt-get update
sudo apt-get install ubuntu-tweak
eu recebi este erro do terminal
