Comment 4 for bug 149203

As written earlier, I had a problem with upgrade from 7.04 to 7.10 using update-manager because of not enough free space. After that I could not get update-manager to give me the option to upgrade to 7.10.

I have the following further information:

I found that I could get update-manager (in feisty) to show the option to upgrade, after copying the correct meta-release file (obtained from changelogs.ubuntu.com) under

.update-manager-core/

and

/var/lib/update-manager/

(I had to be careful that the network proxy setting was correct -- setting network proxy for direct connection instead of the correct server ip address led to these files being replaced by html error messages).

However, on clicking on the upgrade button, the upgrade fails, and update-manager hangs. If I had used update-manager -c from a terminal, the message is:
