Computer Janitor complains that package dash is missing

Once one rolls in updates this problem does not occur.

cruft is actually a different package, FWIW; Computer Janitor is in the computer-janitor package.

I don't seem to be able to reproduce this with a fresh jaunty beta install. Thus, I'll close it, but if it occurs again, please reopen the bug!

This bug affects me though; I tried moving /etc/apt/sources.list to /etc/apt/sources.list.bak and running computer janitor again, same error. How do i go about debugging it/providing you with relevant information?

rumandfruit, does it still occur to you? If it does, could you attach the output of the commands "dpkg --status dash" and "apt-cache policy dash"?

I am getting the same error. I just installed a fresh copy of Jaunty last night. The first package I ran was Computer Janitor because I am going to be working on documentation for it.

The output for dpkg --status dash:

I hope this is helpful.

One additional note. I am running Jaunty within VirtualBox 2.2.0 r45846.

I apologize. I should have run may updates before posting above. When updates are ran, the error is corrected.

I have the same issue after upgrading from intrepid to jaunty.

dpkg --status dash gives the same output as DB Cummings, here is the output from apt-cache policy dash :

$ apt-cache policy dash
dash:
  Installé : 0.5.4-12ubuntu2
  Candidat : 0.5.4-12ubuntu2
  Table de version :
 *** 0.5.4-12ubuntu2 0
        500 http://archive.ubuntu.com jaunty/main Packages
        100 /var/lib/dpkg/status

I can't reproduce this with a fresh jaunty install now. I suspect it depends on exactly which code path gets executed during the installation: perhaps there is one where the package list is not updated correctly (but that gets fixed when update-manager updates is automatically).

However, it should be pretty rare for someone to need to run Computer Janitor straight after an install, so I'll not worry about this.

Hola,

any heLP..............................................?

I get a similar error. I'm running Ubuntu 9.10. I got this error after trying to install cubemodel according to these instructions: http://forum.ubuntu-fr.org/viewtopic.php?id=259077&p=1

I've since disabled all third-party repositories in sources.list.

I think it's a bug in apt_pkg python module, not computer janitor per se. See the attached file for proof.

I found the source of the error: for some reason, Ubuntu main updates had been disabled. Once I enabled them again, Computer Janitor launched without any problems. I'm marking this bug as invalid because it was my mistake.
If anyone else is experiencing this problem, please attach a copy of /etc/apt/sources.list and re-open the bug.
