Same here. Some more information: I'm running Dapper plus edgy enhancements (switching in progress...), and since the latest upgrade of apt (0.6.44.2ubuntu4), aptitude (0.4.1-1.1ubuntu2) and dpkg (1.13.22ubuntu4). Now when I invoke aptitude all those progress bar increase in parts of seconds, only the building of the package state takes up to minutes (on a AMD K7 2800+), and the cpu usage is high up in the nineties. Updating the packages list and installing/upgrading packages works fast as usual.
Pls let me know if I can be of more help to track this down. -- aptitude pegs cpu for extended period of time on startup https://launchpad.net/bugs/51893 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
