Frankly that went over my head, so unsure how to respond. :)
I used a VM to test (manually updating by installing a deb) and all
issues disappeared - that was my "test". I suppose that's not good
enough according to your comment.
Perhaps let's just close this issue? I'll need to wait for ubuntu 2
Public bug reported:
Ubuntu focal/20.04 has logrotate version 3.14.0 which is ancient. There
have been multiple important bugfixes since then
(https://github.com/logrotate/logrotate/releases).
Ubuntu hirsute/21.04 does include the latest version, but that isn't an
LTS version, so is not an option
