When this commands runs it hogs CPU up to 100%. It happens to me on Ubuntu 11.10 and has been known to happen to others. I found two "fixes": http://naveenubuntu.blogspot.com/2011/10/ubuntu-update-apt-xapi-takes-lot-of-cpu.html and http://sapnwnewbie.blogspot.com/2010/11/high-cpu-usage-by-update-apt-xapi.html Comments, anyone? PS: I still have Synaptic as a carry-over from 11.04 because I upgraded. People who did a clean 11.10 install may not have Synaptic unless they subsequently installed it.
