Hi, I just took a look at the tracker and noticed that opm-common is level 3 and opm-simulators is level 2. If build attempts for level 3 come after level 2 that migth explain the failure in the logs [1] and opm-common should be in a level before opm-simulators.
If there is anything that I need to do on my side as a maintainer then please let me know. Cheers, Markus [1] https://buildd.debian.org/status/fetch.php?pkg=opm-simulators&arch=amd64&ver=2021.10-4%2Bb1&stamp=1648476056&raw=0
