Debian Unattended Upgrades: Upgrade Third Party mono packages

When using the official third-party repository of mono in Debian, unattended Upgrades will not upgrade the mono packages unless you allow the origin. To do so, edit your /etc/apt/apt.conf.d/50unattended-upgrades , which may look like this:

Unattended-Upgrade::Origins-Pattern {
      "o=Debian,n=${distro_codename}";
      "o=Debian,n=${distro_codename}-updates";
      "o=Debian,n=${distro_codename}-proposed-updates";
      "o=Debian,n=${distro_codename},l=Debian-Security";
};

To also update mono packages on Debian Stretch, add XamarinStretch as Origin:

Unattended-Upgrade::Origins-Pattern {
      "o=Debian,n=${distro_codename}";
      "o=Debian,n=${distro_codename}-updates";
      "o=Debian,n=${distro_codename}-proposed-updates";
      "o=Debian,n=${distro_codename},l=Debian-Security";
      "o=XamarinStretch";
};

If you use another Debian version or Distribution, like Jessie or Ubuntu, search for the file /var/lib/apt/lists/download.mono-project.com_repo_*_InRelease and check the “Origin: ” line and adjust the origin in the config file accordingly.

Repositories with empty Origin like packages.sury.org

If you find that the Origin of the packages in the repository is not given, then you can also tell unattended upgrade to select them based on the given site. For example, this works for the packages from sury.org:

"site=packages.sury.org";

Test your changes

To test if it works, you can run unattended updates manually like this (as root or with sudo):

unattended-upgrade -d

If this made your day or you still have problems, just drop a comment.

Debian Linux: Update packages automatically

Filed under: Linux,Server Administration — Tags: , , , , , — Christopher Kramer @ 20:50

Here is how you configure automatic (security) updates on Debian:

aptitude install unattended-upgrades

Here you can configure it:

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

This could look like this:

Unattended-Upgrade::Origins-Pattern {
        "origin=Debian,archive=stable,label=Debian-Security";
};
Unattended-Upgrade::Package-Blacklist {
// add packages here that need manual steps like this:
//        "vim";
}
Unattended-Upgrade::AutoFixInterruptedDpkg "true";
Unattended-Upgrade::MinimalSteps "true";
Unattended-Upgrade::InstallOnShutdown "false";
Unattended-Upgrade::Mail "root";
Unattended-Upgrade::MailOnlyOnError "true";
Unattended-Upgrade::Remove-Unused-Dependencies "true";
Unattended-Upgrade::Automatic-Reboot "false";
Acquire::http::Dl-Limit "200";

Now create the following file:

nano /etc/apt/apt.conf.d/02periodic

With this content:

// Enable the update/upgrade script (0=disable)
APT::Periodic::Enable "1";

// Do "apt-get update" automatically every n-days (0=disable)
APT::Periodic::Update-Package-Lists "1";

// Do "apt-get upgrade --download-only" every n-days (0=disable)
APT::Periodic::Download-Upgradeable-Packages "1";

// Run the "unattended-upgrade" security upgrade script
// every n-days (0=disabled)
// Requires the package "unattended-upgrades" and will write
// a log in /var/log/unattended-upgrades
APT::Periodic::Unattended-Upgrade "1";

// Do "apt-get autoclean" every n-days (0=disable)
APT::Periodic::AutocleanInterval "7";

Of course the server needs to be able to send mails so it can send mails in case of problems.

You can test it like this:

# mail -s test mail@example.com
My testmail
.
EOT

Hope this helps somebody.

Update: Some updates caused dpkg questions about changed config files and therefore failed.

For example php5-fpm did ask this:

Setting up php5-fpm (5.4.4-14+deb7u10) ...

Configuration file `/etc/php5/fpm/pool.d/www.conf'
 ==> Deleted (by you or by a script) since installation.
 ==> Package distributor has shipped an updated version.
   What would you like to do about it ?  Your options are:
    Y or I  : install the package maintainer's version
    N or O  : keep your currently-installed version
      D     : show the differences between the versions
      Z     : start a shell to examine the situation
 The default action is to keep your current version.
*** www.conf (Y/I/N/O/D/Z) [default=N] ? dpkg: error processing php5-fpm (--configure):
 EOF on stdin at conffile prompt

This caused PHP5-FPM to stop and all PHP sites to show an Internal Server Errror…

So you don’t run into this problem, create /etc/apt/apt.conf.d/local with this content:

Dpkg::Options {
   "--force-confdef";
   "--force-confold";
}

This tells DPKG to keep the old config file. It will create .dpkg-dist files with the package distributer’s version. More information on this can be found here.
