Need some suggestions on a borked upgrade

[Bruce Labitt]

Been quiet on the list.

Upgrade from Ubuntu 14.10 to 15.04.  Apt seems to be hung up with 
removing a single file - which is old and not needed.  But because of 
this the upgrade is severely screwed up.  Not sure if it will boot again 
properly.  I just downloaded an 15.04 iso to burn to a usbstick to act 
as a rescue if needed.

Package is octave3.2-info, for some reason it has dependencies on perl.  
Perl is apparently used by a lot of packages in some way, and all of 
these necessary packages are "half installed".  It got so bad that 
dist-upgrade hung because there were too many errors.

There is some sort of directory issue, which generates an error message 
if I attempt to apt-get remove octave3.2-info.
I think, if I can remove or delete this file (and remove references to 
it) perhaps the rest of the install will go through.  This, of course 
sound 'dangerous' but I have run out of ideas.

Any suggestions?  apt-get -f install returns the error message. apt-get 
remove returns the same error.  Looking for a few ideas. I'll try to use 
some of them tonight to attempt a fix.  Got to visit Mom now...

Regards,
Bruce
