Occasionally I have connection problem with apt-get (typically because I use it behind a proxy and try to install/upgrade flash). I have been trying sending Ctrlc but it would not stop. I thought it was something wrong with synaptic but obviously I just tried with a terminal and don't know how to stop it now.

This is a known bug:

The bug report mentions that even Ctrl + \ doesn't work.


  • Suspend the job: Ctrl + Z

  • Kill it: sudo killall apt-get
