Devuan Upgrade: 4 to 5 Daedalus

nabbisen - Sep 1 '23 - - Dev Community

Summary

Devuan is a fork of Debian GNU+Linux without systemd.

Its new major version, 5 - Daedalus, was released 🎉 this August, on 2023-08-14. Nearly two years had passed since was the previous 4 - Chimaera.
It is based on Debian 12 - Bookworm with Linux 6.1 (LTS) ☺️

I have recently upgraded my workstations, helped by the official guide "Upgrade to Daedalus". This post is the record.

Environment

  • OS: Devuan GNU+Linux
    • Version: 🌟 5 🇩aedalus ⬅️ 🌟 4 🇨himaera
  • Init System: OpenRC
  • Desktop Environment: Xfce

Basic Steps

The first and also primary step is to replace package repositories of Chimaera with Daudalus':

# nvim /etc/apt/sources.list
Enter fullscreen mode Exit fullscreen mode

Before actual update, confirm your shell is independent on python. It is important when you use fish:

$ # (optional)
$ bash
Enter fullscreen mode Exit fullscreen mode

Run the packages update. It will take long to update many packages, and also ask you a few questions:

# apt update
Enter fullscreen mode Exit fullscreen mode

Stop xscreensaver before upgrade if it is running:

$ killall xscreensaver
Enter fullscreen mode Exit fullscreen mode

Run the distribution update:

# apt dist-upgrade
Enter fullscreen mode Exit fullscreen mode

Finally, clean up:

# apt autoremove --purge
# apt autoclean
Enter fullscreen mode Exit fullscreen mode

The below is the description with both result and questions printed out at each step.

Description

All doas from OpenBSD's can be replaced with sudo.

Confirm compatibility

You should read Devuan Daedalus Release Notes before start.

Replace repos

Create backup for the previous version as needed with command-lines such as:

$ # (optional)
$ doas cp -p /etc/apt/sources.list /etc/apt/sources.list.bk-chimaera
Enter fullscreen mode Exit fullscreen mode

Let's move to Daudauls':

$ doas nvim /etc/apt/sources.list
Enter fullscreen mode Exit fullscreen mode

by replacing chimaera with daedalus:

< deb http://deb.devuan.org/merged chimaera main non-free contrib
< deb-src http://deb.devuan.org/merged chimaera main non-free contrib

Enter fullscreen mode Exit fullscreen mode

Update packages

We are now ready. Run the update for packages:

$ doas apt update
Enter fullscreen mode Exit fullscreen mode

It will print out as below and also ask you the first question:

There are a few questions left.

Setting up devuan-keyring (2023.05.28) ...

Configuration file '/etc/apt/trusted.gpg.d/devuan-keyring-2016-archive.gpg'

    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.

I chose to overwrite it as above. Then it will continue:

Note: Occasional problem occurred by shell dependent on Python

When the shell used is fish, apt update above will bring the error in console like below:

Even with them, it seemed to be able to complete the upgrade. However, I don't know it was perfect or not.

Stop xscreensaver if running

Run:

$ killall xscreensaver
Enter fullscreen mode Exit fullscreen mode

Update distro

Next, run the command-line:

$ doas apt dist-upgrade
Enter fullscreen mode Exit fullscreen mode

The process is much simpler than the packages'. It will print out like:

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Calculating upgrade... Done
The following packages were automatically installed and are no longer required:

Use 'apt autoremove' to remove them.
