Repository PGP key needs to be updated on your system

Chances are that you see this error when running "flatpak update" from a command line: "error: GPG signatures found, but none are in trusted keyring." The error is a bit cryptic and doesn’t tell the real issue. Anyway, the GPG key used to sign Nuvola Flatpaks Repository needs to be updated on your machine. I apologize for the inconvenience. It should not happen again.
The update of a PGP key consists of a few easy steps. Please refer to the updated Nuvola 4.15 release announcement for details: https:/
