I am currently in the process of trying to install OpenProject on a fresh instance of UCS 5.0
When I run ‘univention-app install openproject’ I get errors looking like this:
W: GPG error: https://updates.software-univention.de/4.2/maintained 4.2-5/amd64/ Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY D293E501A055F562
E: The repository 'https://updates.software-univention.de/4.2/maintained 4.2-5/amd64/ Release' is not signed.
When I run ‘apt-key list’ I get this:

I have been looking at this post:
And tried the solution, but only the dirty workaround works…
If you can advice, I’d much appreciate
