Estou executando 16.04 LTS e recebo "Falha ao baixar arquivos de pacote". (tradução livre, minha distro é em português).
Eu tentei esta solução , mas sempre que clico em Okay, ele me pede para recarregar. Então, quando ele tenta recarregar, ele falha novamente com o mesmo erro.
Este é o erro de saída:
W:An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://repository.spotify.com stable InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY EFDC8610341D9410, W:https://content.runescape.com/downloads/ubuntu/dists/trusty/InRelease: Signature by key AAC9264309E4D717441DB9527373B12CE03BEB4B uses weak digest algorithm (SHA1), W:The repository 'http://ppa.launchpad.net/osmoma/audio-recorder/ubuntu xenial Release' does not have a Release file., W:Data from such a repository can't be authenticated and is therefore potentially dangerous to use., W:See apt-secure(8) manpage for repository creation and user configuration details., W:Failed to fetch http://repository.spotify.com/dists/stable/InRelease The following signatures couldn't be verified because the public key is not available: NO_PUBKEY EFDC8610341D9410, E:Failed to fetch http://ppa.launchpad.net/osmoma/audio-recorder/ubuntu/dists/xenial/main/binary-amd64/Packages 404 Not Found, W:Some index files failed to download.

Eu preciso de ajuda, pois estou precisando atualizar alguns arquivos e me preparar para a atualização de abril.
