It all got worse and I also wasn’t able to publish one of main most important CVs anymore. I have got the same error as in Unable to publish new version of content view with filter.
The publish task paused. I could resume and it would take a couple of minutes until it paused again, with slightly different numbers, always sticking at 26%. Looking into the pulpcore database table core_repositorycontent it seems that there are a lot of these cases, so I eventually tried to cancel that task, but in vain. Whatever I have tried, it always kept some locks which prevented me from publishing a new version or removing that broken version…
In the end, it looked like a completely dead end to me, again, and I am back again at 3.18.3. So far I haven’t managed to get this server updated to 4.0 or 4.1 so that I can at least do the standard things of syncing, publishing, promoting and delivering content to my clients, accepting the broken el8 module applicability and the extremely slow publish of CVs with filters…
