Whenever I run apt-update i get the error NO_PUBKEY 871920D1991BC93C. I have tried removing the key file, and I have removed it multiple times and re-added it via curl, wget, and apt-key commands each time. Neither work, all resulting in the same error. Please tell me what to do. I’m running the latest ubuntu droplet.

Heya,
As mentioned you can share the full error message so we can advise you which step is best to take in your particular case.
You can also try to remove and then re-add the key then run the
apt-updatecommand again, however I’ll recommend to provide us with the full error so we can make sure this is the best way to deal with the problem.Regards
Heya,
The
NO_PUBKEY 871920D1991BC93Cerror indicates that your system is missing the public key needed to authenticate packages from a repository.Try adding the key using a keyserver. In some cases, certain keyservers may be unreliable. You can add the missing key using a trusted keyserver like
keyserver.ubuntu.com:If this works, you should see a success message and the key will be added.
Heya,
The error you’re encountering indicates that the APT package manager is unable to verify the GPG signature of some repository because it lacks the necessary public key.
Can you share the complete error that you are getting here so I could advise you further?
Also, does this happen with a fresh Droplet or did it happen after installing some specific packages?
