[SOLVED] PBS trixie repo no public key

[citricut]

Hi,

I'm trying to upgrade PBS 3 to 4 via helper scripts but it seems like the PBS trixie repo has no public key. I was recommended to wait a few days but it hasn't cleared out after a week. Any hint here?

GPG error: http://download.proxmox.com/debian/pbs trixie InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY A7BCD1420BFE778E


Thanks in advance!

Hi,

Have you followed the upgrade guide[0] ?

I personally upgraded my PBS3 to 4, 3 days ago, and it's work like a charm.

Hi @citricut,
is the package proxmox-archive-keyring installed correctly on your system? The meta-package proxmox-backup depends on that so maybe that is not installed as well?

Thanks for the help, I managed to fix it by reverting the repos to bookworm and performing a dist-upgrade. That step is on the upgrade guide but was not implemented in the helper script. I opened a ticket to include it and they have since implemented it

This can be marked solved

Hi,

Real question: why use a script when there is an official guide ?

As i can see the script does not :

• Make a backup of /etc/proxmox-backup to ensure that in the worst case, any relevant configuration can be recovered
• Ensure that you have at least 10 GB free disk space on the root mount point
• Enable Maintenance Mode (yes, it's optional but best practice)

Best regards,
