Hello, that's true, somehow I messed up the version number, sorry. I had libilmbase-dev version 2.5.7-2+b1 installed when I ran into this issue according to my aptitude log.
I also tried out to reproduce the issue again in Docker & succeeded, see the attached Dockerfile. However, after seeing how old both package versions are and that these exact versions were not available at the same time, I do not know how I ended up with exactly these versions and using them until just a few days ago. Maybe another package which wasn't updated for quite a while had a hardlocked dependency. To know for sure, I would need to restore the full list of packages & versions I had installed before upgrading by reading the dpkg logs. Best Regards, Felix Stupp Am Mittwoch, 29.
