I started update-manager
in order to do the 13.04 to 13.10 upgrade. At some point not far into the process, it died with some sort of unexplained error. (There was a message in the console about a Unicode decode failure, but I don't know whether to pay attention to that; Linux GUI programs spew out continual errors and warnings under apparently normal operation.)
When I start it back up now, it just sits there burning CPU, showing the initial "Checking for updates" progress screen. The "Stop" button is greyed-out.
I think that before the thing died the first time, it had gotten part-way, or maybe all the way, through the process of updating my apt files to point to the new release.
At this point, should I just kill the update-manager
process and do a manual apt-get dist-upgrade
from the command line? Is there something I should check first to make sure that won't be a disaster?
