Problem with upgrade of Lubuntu 11.10 to 12.04

[Aere Greenway]

Piske, and all:

Thank you for the idea.  This actually worked, though I had to do the
same for two other packages it needed that the upgrade had taken out.  

I then went to check for updates, and found it wanted to do a "partial
upgrade", which I did, in which it added a single package it needed, but
then at the end insisted on removing it as obsolete.  

After which, it again wanted to do a partial upgrade, which I did,
adding the same package, this time I specified to keep it.  

But after that, it wanted to do a partial upgrade again, so I concluded
it was just looping wanting to do it.  

I terminated the Update Manager, did some other things, then restarted
the Update Manager.  It showed a whole bunch of updates (as before) that
were needed, but said it needed to do a partial update first.  

I had it do a partial upgrade again, and this time, it specified
probably all of the modules that supposedly got upgraded before - 488
megabytes worth.  Reluctantly, I let it do its thing (tying up my
wireless dongle much of the afternoon).  

However, this time, the upgrade went through to completion with no
problems, and it didn't try to take out (obsolete) qjackctl this time.  

I conclude that something went wrong during the original upgrade,
causing it to terminate early.  That would explain why it said it was
12.04, but it still had the look-and-feel of 11.10.  I recall during the
upgrade process I saw a "cc1" step error off (associated with virtual
box), and thought this thing wasn't even going to boot, but it did
boot.  

To its credit, it did eventually get things sorted out.  

Thanks again for your tip that allowed me to restore qjackctl to
operational status.
