[SOLVED] pbs-client for buster signed with unknown gpg key

Aug 10, 2021
Hey folks,

just tried to install pbs-client for Debian Buster according to https://pbs.proxmox.com/docs/package-repositories.html#apt-based-proxmox-backup-client-repository .

It looks that the packages for Buster are not signed with the apt-gpg key mentioned in https://pbs.proxmox.com/docs/package-repositories.html#apt-based-proxmox-backup-client-repository , apt claims : NO_PUBKEY 7BF2812E8A6E88E0 . The gpg-key mentioned in the docs is another one:

pub   rsa4096 2020-11-09 [SC] [verfällt: 2030-11-07]
uid           Proxmox Bullseye Release Key <proxmox-release@proxmox.com>

It seems that no gpg key provided by the download page ( http://download.proxmox.com/debian/ ) is providing the correct key. Tried all below.

key.asc                                            23-Jul-2013 07:29                1703
proxmox-release-bullseye.gpg                       14-Dec-2020 19:10                1187
proxmox-ve-release-4.x.gpg                         09-Mar-2017 12:49                1173
proxmox-ve-release-5.x.gpg                         09-Mar-2017 12:49                1181
proxmox-ve-release-6.x.gpg                         23-May-2019 19:51                1202

Is it possible there is one key missing on the server?

the proxmox-ve-release-6.x.gpg is the correct one for buster:

pub   rsa4096 2018-11-19 [SC] [expires: 2028-11-16]
uid           [ unknown] Proxmox Virtual Environment 6.x Release Key <proxmox-release@proxmox.com>

Thanks fabian, with that key it works.

I did not try it yesterday, just compared the shortened pubkey of the error message against the output of gpg ... . But I thought the shortened key is the beginning, not the end of the "long" pubkey *facepalm*. Just a wrong assumption :rolleyes:.
