merkur,
I also have the same issue as Viking, I have a hybrid and 4 MDs, after Alpha 2.24, I was able to update the core every week, all the way to Beta without any problem, but that not the case with the MDs after Alpha 2.24, I Login in from the core with SSH, and do "apt-get update" & "apt-get dist-upgrade", it will take about 30-45 minutes to get updated, then it will fail the reboot, that happens on all the MDs, so I go back to the WebAdmin and do regenrate MD, then it will put me back to "Version:2.0.0.44.0805082200-Sat June 27" where my Hybrid is "Version: 2.0.0.44.0805082200-Thu Sep 3", after I tried this several times, I just gave up on updating my MDs.
Is there any other way to do this, without reinstalling my Hybrid
