Ubuntu unable to update and upgrade to 14.04: GPG Error [duplicate]

  • 772

I have been looking around the net for solutions but I just cannot get rid of this error.

sudo apt-get update

EDIT: This particular error disappeared upon changing the server to the main Ubuntu server. There were a few errors with 404 not found, and I removed those ppas from the software list. On a sidenote, I recently removed and purged qgis so don't know what its doing there.

  1. I have had the same problem. Run following command to resolve it.

    sudo dpkg-reconfigure -a
sudo apt-get update
sudo do-release-upgrade -d

    and it might work fine this way.
