Antes eu só excluía a chave por essa Como posso remover a chave gpg que adicionei usando o apt-key add -?
Edit: Estou apenas tentando isntall websocket com nodejs deste manual link , antes deste erro show eu executo os 3 primeiros comandos daquele manual.
Iniciar Software e amp; Atualiza do traço e vai até a guia Autenticação para excluir chaves incorretas.
Você pode tentar instalar o y-ppa-manager do Synaptic e depois iniciar o PPA Manager no Dash. Clique no ícone Avançado e, em seguida, escolha importar todas as chaves gpg ausentes .
