Eu instalei a versão mais recente do Ubuntu 14.04 Server e tentei
sudo apt-get update
Eu recebi este erro:
W: GPG error: http://in.archive.ubuntu.com trusty Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 16126D3A3E5C1192
Eu tentei adicionar a chave com este comando:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 16126D3A3E5C1192
E mais uma vez tentou atualizar, depois vi este erro:
W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used.
GPG error: http://in.archive.ubuntu.com trusty Release: The following signatures were invalid: BADSIG 16126D3A3E5C1192 Ubuntu Extras Archive Automatic Signing Key <[email protected]>
W: Failed to fetch http://in.archive.ubuntu.com/ubuntu/dists/trusty/Release
W: Some index files failed to download. They have been ignored, or old ones used instead.
Qualquer sugestão.
