Binary package hint: update-manager

Description:    Ubuntu 7.10
Release:        7.10

Hi, I'm trying to update (using System / Administration / Update
Manager) from 7.10 to 8.04, and getting this message:

----------------------------
A unresolvable problem occurred while calculating the upgrade.

 This can be caused by:
 * Upgrading to a pre-release version of Ubuntu
 * Running the current pre-release version of Ubuntu
 * Unofficial software packages not provided by Ubuntu

If none of this applies, then please report this bug against the 'update-manager' package and include the files in /var/log/dist-upgrade/ in the bugreport.
----------------------------

I'm not doing anything with pre-releases, and I don't think there's
anything unusual on this machine that might be getting in the way.  I've
previously upgraded from 6.10 to 7.04 to 7.10 with pretty much the same
stuff.

I'm attaching main.log from /var/log/dist-upgrade.  It ends with:

2008-10-04 13:37:14,941 DEBUG Marking 'ubuntu-desktop' for upgrade
2008-10-04 13:37:15,317 DEBUG The package 'nvidia-glx' is marked for removal but it's in the removal blacklist
2008-10-04 13:37:34,442 ERROR Dist-upgrade failed: 'A essential package would have to be removed'

I found /usr/share/update-manager/removal_blacklist.cfg and tried
commenting out the nvidia-glx entries, but get the same error as above.

Please let me know if you need to see more logs.

I also found:

https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/249329

Relating to Intrepid, which made me think of looking for
removal_blacklist.cfg and commenting out the nvidia lines.

Thanks for your help!
