When I run
apt-get update, I get this error message:
Err:18 http://dl.google.com/linux/chrome/deb stable Release.gpg The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 6494C6D6997C215E
I understand what causes this issue. I wonder how to fix it.
I tried the most upvoted solution provided in the duplicate link:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 6494C6D6997C215E
I got this new issue which does not seem to be resolved on this website according to the posts I saw:
Executing: /tmp/tmp.jyolnTyZuJ/gpg.1.sh --keyserver keyserver.ubuntu.com --recv-keys 6494C6D6997C215E gpg: requesting key 997C215E from hkp server keyserver.ubuntu.com gpg: keyserver timed out gpg: keyserver receive failed: keyserver error
