Linux bug Cinnamon [closed]

0

I installed Linux Cinnamon 18.2 (Sonya) 3 weeks ago, but today an alert appeared saying that an error occurred and Cinnamon would be restarted. After this, by disinheritance of conscience, I decided to also restart the notebook. But now the update manager is showing this error:

When attempting the command:

sudo apt-key adv --keyserver pgp.mit.edu --recv-keys 97C215EF
sudo apt update

The message appeared in the first command:

Executing: /tmp/tmp.S24tOjXm89/gpg.1.sh --keyserver
pgp.mit.edu
--recv-keys
97C215EF
gpg: requisitando chave 97C215EF de servidor hkp - pgp.mit.edu
gpgkeys: key 97C215EF not found on keyserver
gpg: nenhum dado OpenPGP válido encontrado.
gpg: Número total processado: 0
gpg: erro de comunicação com o keyserver: key not found
gpg: erro de comunicação com o keyserver: chave pública incorreta
gpg: Recebimento de informação do keyserver falhou: chave pública incorreta

And in the second of the update after reading all the packages:

W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://dl.google.com/linux/chrome/deb stable Release: As assinaturas a seguir não puderam ser verificadas devido à chave pública não estar disponível: NO_PUBKEY 6494C6D6997C215E
W: Falhou ao buscar http://dl.google.com/linux/chrome/deb/dists/stable/Release.gpg  As assinaturas a seguir não puderam ser verificadas devido à chave pública não estar disponível: NO_PUBKEY 6494C6D6997C215E
W: Falhou o download de alguns ficheiros de índice. Foram ignorados ou os antigos foram usados em seu lugar.

How do I fix this error?

Regarding the key error, I was able to resolve it as follows:

  

I downloaded the public key link , then   I went to Application sources > > authentication keys and added the   key that I downloaded.
