Debian 10 (Buster) Upgrade Notes

Debian was upgraded to Debian 10 (Buster) in XiVO 2020.10 release.

Warning

Upgrade from versions earlier than XiVO Boréalis (2018.16) are not supported. You MUST first upgrade to at least XiVO Boréalis (2018.16) or more before upgrading to XiVO Freya.

Before the upgrade

Important

Make sure you have sufficient space for the upgrade. You should have more than 2GiB available in the filesystem that holds the /var and / directories.

  • It is not possible to upgrade from XiVO below Boréalis (2018.16) version. You first need to upgrade to XiVO Boréalis.

  • Note that the upgrade will take longer than usual because of all the system upgrade.

  • You MUST deactivate all non-xivo apt sources list:

    • in directory /etc/apt/sources.list.d/ you should only have the files xivo-dist.list and (from Aldebaran) docker.list pgdg.list.

    • you MUST suffix all other files with .save to deactivate them.

  • You MUST check the Debian sources list are correct: the file /etc/apt/sources.list must contain the following and only the following:

    deb http://ftp.fr.debian.org/debian/ stretch main
deb-src http://ftp.fr.debian.org/debian/ stretch main

deb http://security.debian.org/ stretch/updates main
deb-src http://security.debian.org/ stretch/updates main

# stretch-updates, previously known as 'volatile'
deb http://ftp.fr.debian.org/debian/ stretch-updates main
deb-src http://ftp.fr.debian.org/debian/ stretch-updates main

  • You may want to clean your system before upgrading:

    • Remove package that were automatically installed and are not needed anymore:

      apt-get autoremove --purge

    • Purge removed packages. You can see the list of packages in this state by running dpkg -l | awk '/^rc/ { print $2 }' and purge all of them with:

      apt-get purge $(dpkg -l | awk '/^rc/ { print $2 }')

    • Remove .dpkg-old, .dpkg-dist and .dpkg-new files from previous upgrade. You can see a list of these files by running:

      find /etc -name '*.dpkg-old' -o -name '*.dpkg-dist' -o -name '*.dpkg-new'

After the upgrade

  • After having check your network configuration and the grub configuration, you MUST reboot your system. It is necessary for the upgrade to the Linux kernel to be effective.

  • Check that customization to your configuration files is still effective.

    During the upgrade, new version of configuration files are going to be installed, and these might override your local customization. For example, the vim package provides a new /etc/vim/vimrc file. If you have customized this file, after the upgrade you’ll have both a /etc/vim/vimrc and /etc/vim/vimrc.dpkg-old file, the former containing the new version of the file shipped by the vim package while the later is your customized version. You should merge back your customization into the new file, then delete the .dpkg-old file.

    If collectd is installed, you will need to do the same with the /etc/collectd/collectd.conf file.

    You can see a list of affected files by running find /etc -name '*.dpkg-old'. If some files shows up that you didn’t modify by yourself, you can ignore them.

  • Purge removed packages. You can see the list of packages in this state by running dpkg -l | awk '/^rc/ { print $2 }' and purge all of them with:

    apt-get purge $(dpkg -l | awk '/^rc/ { print $2 }')
