If a software source is disabled while viewing the details view for a package and that package is no longer available, the statement "software catalogue needs updating" is displayed

The 'Microsoft core fonts' package seems to illustrate this behaviour.

This also seems to affect uninstalled java packages in 'partners' when the partners repo is disabled.

Testing with the current release of software-center, 1.1.23, the result when executing the steps in the description above has changed a bit. Specifically, the "Update Now" button is now hidden, but the "To show information about this item, the software catalogue needs updating." message still remains. So, the issue with pressing "Update Now" is no longer relevant, however, the user is still faced with a somewhat perplexing experience since it's not obvious what should be done.

Note, however, that after navigating back to the "Fonts" list view the "ttf-mscorefonts-installer" package is no longer included in the list, and so the details page for "ttf-mscorefonts-installer" is no longer reachable via the UI from that point.

Michael Vogt has checked in a fix for this one and the fix will be available in the next release of software-center.

With the fix, the message "Sorry, 'ttf-mscorefonts-installer' is not available for this type of computer" is displayed, rather than the previous (cryptic) message "To show information about this item, the software catalogue needs updating."

I opened a new bug to track the issue that I describe at the end of the description above, please see bug 559539 to track that issue.

This bug was fixed in the package software-center - 1.1.25
