Upgrade to Chimaera

Important: Please do read the Devuan Chimaera Release Notes which detail significant changes between the previous and current release.

This document describes how to upgrade to Devuan Chimaera from an existing Devuan Beowulf system. This should not be used for migrations from Debian.

Note that skipping releases is not supported. Upgrade to Devuan Beowulf and ensure that the existing installation is fully up to date before proceeding.

First change /etc/apt/sources.list so that it points to the Chimaera repositories.

root@devuan:~# editor /etc/apt/sources.list

Modify sources.list to look like the one provided. Comment out all other lines.

deb http://deb.devuan.org/merged chimaera main
deb http://deb.devuan.org/merged chimaera-updates main
deb http://deb.devuan.org/merged chimaera-security main
#deb http://deb.devuan.org/merged chimaera-backports main

Update the package lists from the Chimaera repository.

root@devuan:~# apt-get update

If xscreensaver is running, kill it now as it needs to be stopped before it can be upgraded.

root@devuan:~# killall xscreensaver

Now perform the upgrade. It is worth doing this in two stages: upgrade and dist-upgrade

root@devuan:~# apt-get upgrade
root@devuan:~# apt-get dist-upgrade

In the event of any package failures, fix the failed packages then start the upgrade again.

root@devuan:~# apt-get -f install
root@devuan:~# apt-get dist-upgrade

It is usually worth removing packages that were orphaned by the upgrade process and old package archives.

root@devuan:~# apt-get autoremove --purge
root@devuan:~# apt-get autoclean
