Question The repository 'https://autoinstall.plesk.com/grafana/deb stable InRelease' is not signed

Server operating system version

Ubuntu 24.04.2 LTS

Plesk version and microupdate number

18.0.70

Previous issues with Grafana / Monitoring & Plesk are numerous and have been posted by many.
Fortunately, we've had minimum problems with both to date, but it seems our time has finally come, with the advent of Plesk Obsidian 18.0.70
The Grafana Extention auto-update via Plesk Panel just errors out, so we removed it via CLI, cleaned up and the important parts (from all of the errors), are:

plesk bin extension --install grafana
ERR [extension/grafana] The execution of post-install.php has failed with the following message:
ERR [extension/grafana] Execution repository has failed with exit code 1, stdout: , stderr: gpg: keybox '/tmp/tmp1z59bopn.plesk.gpg.home/pubring.kbx' created
~~
ERROR:root:Unable to create repository configuration: apt-get failed to perform update
W: GPG error: https://autoinstall.plesk.com/grafana/deb stable InRelease: The following signatures were invalid: 8BADC1A02FC9C07FB8C20EC0BD11A6AA914BDF7E (untrusted public key algorithm: dsa1024)
E: The repository 'https://autoinstall.plesk.com/grafana/deb stable InRelease' is not signed.
~~

Meantime, again in CLI, we've removed both Grafana and Monitoring to avoid lots of repetitive errors during normal updates
FWIW The plesk-ext-grafana.list content is shown below and plesk-ext-grafana.gpg does exist in /etc/apt/keyrings/

deb [signed-by=/etc/apt/keyrings/plesk-ext-grafana.gpg] https://autoinstall.plesk.com/grafana/deb stable main

Can Plesk shed any light on why this has occurred and / or perhaps more importantly, suggest a resolution?

Hello, @learning_curve . We have an open report about the issue and our engineers are currently reviewing it. I will follow up with more details as soon as possible. Unfortunately, I cannot suggest a workaround at of this point.
