I've been generally happy with Hardy since I upgraded a week or two ago
(and positively excited since I tried a selection of live CDs - waiting
for an opportunity to do a clean install and switch from Ubuntu 64 bit to
Kubuntu 32 bit!)

One problem that has come up twice now: the automatic update - from the
down arrow that appears on the task bar - has frozen. I click the Install
Updates button and get the timer - doesn't get as far as asking for my
root password. The timer just stays on after that, and I can't close the
updates dialog - I never even get the Force Quit dialog when I click the
top right "close" X. I can carry on working, and shut down the computer
when I want to, but the updates are piling up.

I got round it the first time by using apt-get on the command line, which
proceded without trouble (Can't seem to find the command again, so if
anyone can remind me that would be great).

I was wondering if anyone else has experienced this, and if there's a more
permanent solution?
