HI guys, Thanks for the helpful suggestions. 1) I have modified my /etc/apt/sources.list - it is not the standard one from Kubuntu. Most of what I wanted to install couldn't be found with the standard list, so I updated it with some automated website I found via google. 2) I deleted the package from the /var/cache/apt/archives directory and attempted a reinstall after I ran apt-get update. Version 002-1 was downloaded and the problem recurred. 3) I googled for "cpufrequtils debian" and found version 002-2 of the package, which I manually downloaded and installed. It noticed the missing /etc/init.d/cpufrequtils file and it asked me if I wanted to install a new one. I did, and now all seems to be fixed. 4) When I apt-get remove the cpufrequtils package, it does not delete the /etc/init.d/cpufrequtils file - this is strange - I expected it to delete any/all files related to the package.

Re: [Wlug] APT install question

by Mike Perry

Hmmm weird. I just tried to install cpufrequtils on my box and I didn't run into that problem. Sounds like a fluke to me. Try deleting the package from the cache '/var/cache/apt/archives' and reinstalling as Aaron detailed. I ran Kubuntu for a bit and switched back to Ubuntu as I find the integration is much better. But under the hood they should be the same system. When I was running Kubuntu I did find that it already had a cpufreq tool built into its power management. cpufrequtils is in universe and would be an add on. I know Ubuntu's Gnome package manager, Synaptic, has a "fix broken packages" option which may also fix this problem. Perhaps Adapt has something similar. *Ubuntu also has smart if you are familiar with that. sudo apt-get install smart-pm ~Mike > On Sat, 2006-12-30 at 07:11 -0500, Aaron Haviland wrote: > > Andy Stewart wrote, on Dec 29, 2006 at 21:49 EST: > > > -----BEGIN PGP SIGNED MESSAGE----- > > > Hash: SHA1 > > > > > > > > > HI gang, > > > > > > I'm taking my first adventurous steps in the use of a Debian based > > > system (Kubuntu) on my new laptop (LC2464T).

Indeed it should be part of the package you're trying to install. Could you verify that the files does exist? By this point in the installation, the package is fully extracted, just not configured. A quick & dirty version of the dpkg installation procedure (APT is a front-end to dpkg/wget/etc) is: 1) Extract control information from the package. (You can find this stuff in /var/lib/dpkg/info/${PACKAGE}.* 2) Execute pre-install script, if it exists 3) Extract package. 4) Run post-install script, if it exists.

It might be a bug in the package. It might be a fluke. Usually, try re-installing it (as you won't be able to do much else until you get it resolved, anyway...) apt-get install --reinstall cpufrequtils If not... good luck figuring out ubuntu's bug system. Debian's is quite nice, but if you've got a ubuntu bug, you *have* to use ubuntu's BTS instead. (And it appears there are no current bugs filed for ubuntu's cpufrequtils. Interestingly enough, Debian's BTS lists several bugs against the package, but none seemingly related to your problem.) Hmmm... also, how long ago did this happen? Ubuntu doesn't seem to have 002-1 in its archives anymore. The current version is 002-2. I don't know if you're using a front-end to APT, or taking it plain, but you might need to run "apt-get update" to refresh the package lists. That was a bit longer than I meant it to be... good luck!

APT install question

by Andy Stewart

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI gang, I'm taking my first adventurous steps in the use of a Debian based system (Kubuntu) on my new laptop (LC2464T). (No, I'm not trashing Suse on all of my other systems). I've never previously used an APT based system, so in this sense, I'm quite the newbie. I'm getting an error when I install a package, and I'm not sure how to resolve it. I've googled to no avail. Note in the output below that it says that the file /etc/init.d/cpufrequtils does not exist, and yet (I think) this is a file that belongs to the package which I'm trying to install.

Aha! I actually ask this exact question during interviews. :) There could be several reasons, but a common reason is daemons which are still writing to log files which were deleted. Do something like "lsof | grep deleted" and see what's being used. For instance, on my system: python 2323 mailman 3u REG 8,2 0 75931863 /var/log/mailman/error.5 (deleted) So it appears that there was some issue when log rotating where the mailman proc didn't close the old file, so while it doesn't exist in the directory any longer (and therefore won't count via du) it still exists in the filesystem and takes up space (in this case, 0 bytes, but ...) -- randomly Selected Tagline: "I didn't have Scotch Tape for many years, but I sure as hell use it now." - Larry Young, 2002/06/16, discussion about not having email
