Expected behaviour

No error message

Actual behaviour

Error message see above. My distibuted client systems dan't be updated any more

Extra details

This seems to be an issue that more than once happed and was more than once fixed.
I saw that in the net. But I have no idea to whom I can address this issue.
The ambios in git has no issue tracker :-(
Any ideas how you can help me so my customer's systems can be updated again?
My update script catches this error on the remote systems and stops working so I have
no chance to fix anything on the customer's systems out in the field :-(
I guess it is a repository error but who is able to fix it????
At the moment this is a dead end street for me and I'm a little desperate.

Looks like an issue with the specific apt mirror of Armbian. You can wait and hope they will fix the missing release file as it seems to be missing for Bookworm as well.

[DrCWO]

Do you have the chance to ping the Armbian guys and point them to this issue?

[Joulinar]

Looks like they fixed it already. At least I can see release file again

[DrCWO]

Thank you for your effort. I also recognized today that it works again 👍

[MichaIng]

Update to latest DietPi, which replaces the Armbian APT server with our own.

Great news 👍
