I know that this post is slightly old but i just wanted to let people
know that I successfully made the the upgrade from 11.04 to 11.10 on
Zorin OS 5.2. This may not be too much help because I'm still unsure of
exactly what I did but I know that I used a Ubuntu Server 11.10 (x64 but
you can probably use x86 or 32-bit) CD-ROM upgrade. I had some
difficulties with getting my package manager running again but I read
some other bug issues when I had sent my report and something to do with
either apt-get dist-upgrade, apt-get upgrade, or apt-get update did the
trick. And it even upgraded me to the Premium version of Zorin OS 5,
which is suppose to cost a few bucks. My Wine and flash (used Runescape
to test flash plugin) both still worked. Again I'm not %100 on what
exactly I did (my old HDD went bad), but I'm positive the CD-ROM upgrade
and doing something in the terminal with apt-get made this work. Hope
this may help, and I'm trying to accomplish this feat again, but damned
if I can remember.
