Actually, during the dist-manager -d install, I did get a dialog that
was all "unknown character" blocks in the message and on the buttons. I
don't know what it was asking. It didn't appear to block (I never
answered it, not being able to read it), but it was perhaps that
message. I HAVE seen it in the past, but not during this testing session.

I had meant to reproduce and document that weird dialog, but got
distracted by this problem. I'll go back and get more info on that
either over the weekend or Monday, when I have capacity on my VM host to
make another pre-update clone and run the process again.

The only dialog that I recall, apart from the typical "remove these
packages?" type things, was to do with restarting services.
