GPG ERROR NO_PUBKEY: AVISO: Os seguintes pacotes não podem ser autenticados! [fechadas]

22

Acabei de ver alguns erros estranhos em relação às chaves GPG. Ou seja, acabei de adicionar ppa:ubuntu-toolchain-r/test e queria atualizar e depois disso eu consegui:

W: GPG error: http://extras.ubuntu.com trusty Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 16126D3A3E5C1192

Eu tentei resolvê-lo de duas maneiras (desde aqui )

for key in 40976EAF437D05B5 3B4FE6ACC0B21F32 A040830F7FAC5991 030561BEDD45F6C3 16126D3A3E5C1192  ; do sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys $key ; done

mas isso não ajudou (os mesmos erros continuam aparecendo com as mesmas chaves), então tentei fazer isso:

sudo add-apt-repository ppa:webupd8team/y-ppa-manager
sudo apt-get update
sudo apt-get install y-ppa-manager

mas eu tenho isso que abriu meus olhos:

Executar comando:

sudo apt-get update

Para cada chave de 16 caracteres que é relatada como ausente, execute o seguinte com a chave substituída:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys ABCDEFGH12345678
