It is complicated. But mostly our own fault, as this checklist item easily gets lost after the release is technically done. We’ve changed the release process, and the release team now fully owns the online updater, (and understands how it works! - that was previously an engineering secret )
Having said that, I now have good and (not so good news):
Since today, the online updater offers 10.10.0
But while testing updates via admin web interface, I ran into an internal server error 500 while updating from 10.91 to 10.10.0 (and also with some older updates)
I hope, the error does not occur for too many people.
There is an easy workaound, if it happens:
Manually run occ upgrade – that works perfectly fine. I’d always prefer occ upgrade over updating through the web UI.
Well, the web-updater is, let’s say ‘problematic’, since a long time ago. There were several discussions on this topic in the past, most of them with the advice, not using the web-updater any longer.
