@Leo, James I installed the policykit from James' PPA, and the bug is still there (i.e. update-notifier tells me I don't have privileges, rather than prompting for username and password.
However, I found out that when I run update-notifier-kde on the command- line, at the stage where I usually get this error message, there is a prompt for user information on the command line. Filling that in works, and the upgrade goes through. Here's a transcript: skr...@mania:~$ update-notifier-kde 9;6kcmshell(14690) KpkTransactionBar::setBehaviors: Hide! 1 New transaction with tid "/151_abdcacac_data" New transaction with tid "/152_deaabdbc_data" removing transaction from pool : "/151_abdcacac_data" removing transaction from pool : "/152_deaabdbc_data" Attempting to obtain authorization for org.freedesktop.packagekit.system-update.
