Formatting of “Release Notes” window

Question

I was trying to upgrade from 11.04 to 11.10 following this guide. If you take a look at the image from step 3:

The content inside the Release Notes window is formatted correctly. Now, this is my Release Notes window after I click the Upgrade button:

As you can see, the content is not being formatted at all.

How can I solve this?

Answer 1

Workaround:

Run:

gconf-editor /apps/update-manager

Clear the value in key "check_new_release_ignore"

Run:

killall -r check-new-release-gtk
/usr/lib/update-manager/check-new-release-gtk

Result:

The update-manager window is probably missing the show_uri (webkit.webview). Looking at update-manager on 11.10, it has a DistUpgradeFetcher.py (showReleaseNotes) that falls back to text for some reason (maybe something in ReleaseNotesViewer.py ?).

Please file a bug report about it:

ubuntu-bug update-manager

Answer 2

Well, to be honest on your own you cannot solve this unless you are a coder and willing to submit a patch against the code for the update manager ;).

That happens because the two windows you see are using different methods for rendering the text, and this can only be fixed at the code level (not by simply tweaking some setting).
