- How do I fix the GPG error “NO_PUBKEY”? 11 answers
When I run the command:
sudo apt-get update
I got this following warning:
There is no public key available for the following key IDs: 1397BC53640DB551
This is the only warning I got and I do not get any Error.
How I can fix it and what the key 1397BC53640DB551 is all about?
