here is how i solved this problem.
1) close>代码:
sudo pkill apt
sudo apt-get clean
3) start update manager and hit "check".
3a) if you have any updates, install the updates.
4) close update manager.
warning: i received this problem when doing an update, even worse, when doing a kernel update. this problem forced only some of the packages to install so a reboot, as some suggest, would spell disaster in my case. fix your problem before rebooting!
