Error saying that public key is not available

Asked By 20 points N/A Posted on -


Please look at the error message mentioned below.

It says “W: GPG error: natty release: The following signature couldn’t be verified because the public key is not available: NO_PUBKEY A6804EA8EAE0D85C”.

I visited the respective site, but found nothing. If you have any idea about the error message, please let me know.

Error saying that public key is not available


Hello Kathy,

To resolve that issue, try the following:

  • First you will need to open a terminal by pressing ctrl + alt + t then type the following: sudo apt-get update. After that retry.
  • If you still get the error, try removing  the PPA to smooth things over,  and then re-add if you would like to.
