Eu tenho 3 sistemas Ubuntu. Um servidor de 64 bits que executa alguns daemons, um servidor de 32 bits que executa alguns daemons e um laptop de 64 bits que eu uso para controlá-los e fazer várias coisas.
Todos os sistemas parecem ter as mesmas fontes definidas e parecem ter as mesmas chaves apt. Um sistema, o servidor de 64 bits, fornece os principais erros (repositório não assinado) no apt-get update:
Alguém pode ver o que me falta ou sugerir onde procurar? Outras mensagens / problemas de erros-chave que vejo podem estar relacionados com a obtenção de uma chave perdida especificada, mas não obtenho esse detalhe nos meus avisos.
