High CPU load when installing updates

Asked by James Gauth on 2007-06-06

When clicking the Install Updates button, the subsequent update installation uses 100% CPU for a very long time. When using apt in the terminal there is usually only a minor amount of CPU usage which leads me to believe that the update-manager apt wrapper is causing the load. I have no other Ubuntu boxes on hand so I can't test to see if this is specific to my machine. Is this something anyone is aware of?

well it depends, is this while gettings updates, actually downloading them, or installing them. For installing it is perfectly normal, but for downloading that may be an issue

Well, usually the updates are quite small, so the downloading section might complete very quickly. It'd probably be during the installation side.

If I do 'apt-get update' and then 'apt-get upgrade' (which, I'm pretty sure does the same thing as update-manager), I can happily leave apt-get running in the terminal and get on with other work. If I use update-manager, basically it uses so much CPU that redraw doesn't even work. If I switch to another application, the switch only takes place when the installation is complete (or if it's a really really long installation, it may get around to switching after a long while).

Why is it perfectly normal for installation?

I've reverted to using update-manager's notification area icon to find out if updates are available and I now use an application launcher widget to run apt-get upgrade.
