Auto Update Check doesn't work after Upgrading to 9.04 (wrong permissions for cron job)

[Thomas Winteler (Win-Soft)]

Binary package hint: update-notifier-kde

Hello

My System:
lsb_release -rd
Description: Ubuntu 9.04
Release: 9.04

apt-cache policy update-notifier-kde
update-notifier-kde:
  Installed: 0.19
  Candidate: 0.19
  Version table:
 *** 0.19 0
        500 http://archive.ubuntu.com jaunty/main Packages
        100 /var/lib/dpkg/status

Earlier i have successfully upgraded my Kubuntu from 8.10 to 9.04.. no Problems, just the daily automatically update checks doesn't work. So i need to do that manually with sudo apt-get update. After the manually update check step, the update-notifier-kde icon appears on tray, i can click on it and upgrade my system.

I also can run manual update check over KPackageKit..

I searched, asked around and found that (german): http://forum.ubuntuusers.de/topic/nach-update-auf-kubuntu-8.10:-automatische-up/?highlight=ausfuhrungsrecht#post-1739269
This german description means, that the same Problem was on upgrading to 8.10.. so i tried that steps..

The Package update-notifier-kde was installed on my System..

/etc/apt/apt.conf.d/10periodic:

APT::Periodic::Update-Package-Lists "1";
APT::Periodic::Download-Upgradeable-Packages "0";
APT::Periodic::AutocleanInterval "0";
APT::Periodic::Unattended-Upgrade "0";

/etc/apt/apt.conf.d/50unattended-upgrades:

// Automatically upgrade packages from these (origin, archive) pairs
Unattended-Upgrade::Allowed-Origins {
        "Ubuntu jaunty-security";
// "Ubuntu jaunty-updates";
};

// List of packages to not update
Unattended-Upgrade::Package-Blacklist {
// "vim";
// "libc6";
// "libc6-dev";
// "libc6-i686";
};

// Send email to this address for problems or packages upgrades
// If empty or unset then no email is sent, make sure that you
// have a working mail setup on your system. The package 'mailx'
// must be installed or anything that provides /usr/bin/mail.
//Unattended-Upgrade::Mail "root@localhost";

Then i saw that i (and root) have no execute permission on /etc/cron.daily/apt

ls -l /etc/cron.daily/apt
-rw-r--r-- 1 root root 8686 2009-04-17 06:27 /etc/cron.daily/apt

All other scripts in /etc/cron.daily/ has rwxr-xr-x.. so i run:
sudo chmod aou+x /etc/cron.daily/apt

I think my problem is solved... i will come back later to confirm it.. or send more information.

hello

so, i can now confirm, that above steps:

ls -l /etc/cron.daily/apt
-rw-r--r-- 1 root root 8686 2009-04-17 06:27 /etc/cron.daily/apt

All other scripts in /etc/cron.daily/ has rwxr-xr-x.. so i run:
sudo chmod aou+x /etc/cron.daily/apt

..are working... but, if the automatically or manually update check run's in backgroud, phyton goes to 50% cpu usage for few minuts, after that the update icon apears in systray..

Any idea why phyton eating cpu, just for a update check?

That would be because the update checker/notifier is written in python, making it slow and bloated.
I'm rewriting it to be a teensy tiny C++ KDE daemon module for 10.04.

Anyway, the problem where the cron job has the wrong permissions on upgrade isn't update-notifier-kde's fault. It never directly interacts with it at all. I'm moving the bug to apt in hopes that the apt gurus have a better idea of how this could happen. (And also the cron job comes from the apt package)
