[knot-resolver-users] upstream package repositories - signing key update

Hi, the package signing key for our upstream repositories has expired and Debian and Ubuntu users with existing installation need to manually update the knot-resolver-release package to fix the issue: wget https://secure.nic.cz/files/knot-resolver/knot-resolver-release.deb dpkg -i knot-resolver-release.deb apt update Otherwise, apt update will report following errors and no new updates will be installed. W: GPG error: http://download.opensuse.org/repositories/home:/CZ-NIC:/knot-resolver-lates… InRelease: The following signatures were invalid: EXPKEYSIG 74062DB36A1F4009 home:CZ-NIC OBS Project <home:CZ-NIC@build.opensuse.org> E: The repository 'http://download.opensuse.org/repositories/home:/CZ-NIC:/knot-resolver-latest/Debian_10 InRelease' is not signed. N: Updating from such a repository can't be done securely, and is therefore disabled by default. I apologize for the inconvenience. -- Tomas Krizek PGP: 4A8B A48C 2AED 933B D495 C509 A1FB A5F7 EF8C 4869
