I've just freshly installed Mint 13 KDE after I had some issues with my Mint 12 installation - rather than spend a bunch of time trying to fix a version that will be obsolete in less than a year, I figured I'd just upgrade to Mint 13. After a fresh install, I ran the update manager and found that I had an update to do (mintupdate 4.4.2). I clicked install updates and after giving it the ok to install the updates, the manager has appeared to be hung. It's been like this for over a day now.
Is it ok to kill it and retry through the terminal?
