Hi!
On Debian Stretch, suddenly I have the following messages:
W: GPG error:
http://security.debian.org/debian-security stretch/updates InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 9D6D8F6BC857C906 NO_PUBKEY 8B48AD6246925553
W: GPG error:
http://http.us.debian.org/debian stretch InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 8B48AD6246925553 NO_PUBKEY 7638D0442B90D010
I successfully manually (re)imported the keys into gpg, but when I try to pass them to apt, I have the following error:
apt-key adv --keyserver pgpkeys.mit.edu --recv 8B48AD6246925553
Executing: /tmp/tmp.U8J57UUNyV/gpg.1.sh --keyserver pgpkeys.mit.edu --recv 8B48AD6246925553
gpg: key 8B48AD6246925553: public key "[User ID not found]" imported
gpg: Total number processed: 1
gpg: imported: 1
gpg: WARNING: nothing exported
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0
I exported to a file and verified that it does contain a proper gpg key. It seems that my apt does not recognize gpg keys anymore. Most probably a package broke something, but after hours trying to figure out how to reset the apt keys, nothing works. Anybody would have an idea?
Thanks,
Mathias
