Post update? What's that?
Anyway, the software-update was performed at perhaps midnight or 1am, and left to do its thing. The browser-based interface eventually gave me an error message, which I wish I had written down now. Something about some item or other having timed out. I could still see disk activity going on for some while, though, on the server, so I figured it was still doing the update. For some while I periodically switched the KVM switch over to the server to watch for the machine to do its expected automatic reboot at the end of the update, but it hadn't done it yet by the time I headed to bed at around 2:30 am.
Today at perhaps 11am or noon, I checked the machine again, via the KVM switch, and it clearly hadn't restarted itself, so I pulled up the web-interface from the Windows machine and issued a restart, then sat back and watched, through the KVM switch, the machine go through its shutdown and restart process.
I then left to do other things. This evening I finally came back, went to check my email... and discovered I couldn't get it to work.
Now, so far as I know, SME would NOT have taken many, many hours to finish it's software update. So far as I know, it shouldn't take more than an hour or two. Certainly not half a day!
In any event, the interface-page that displays any updates are ready now shows there being no updates. And, IIRC, did so last night after I'd initiated the update.
Oh yes, and curuously enough, if I try to use Horde, the server's email web-interface, I get Login failed.
