Responding to Brian Murray in comment #15: This morning, update-notifier says that I have 1 new update waiting. Running apt-get upgrade (without applying any changes) shows that the update is the libgksu2-0 package.
Launching update-manager from the command line shows that the bug is still present (the GUI displays an empty list of updates and an active Install Now button) but there is no console text output. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1211511 Title: Text not visible in Software Updater dialog (update-manager GUI) when updated software is available.
