Updating to Chimaera - Marginally Painless

…or at least, it would be if I hadn't made a small mistake & someone in some mirror hadn't made a bigger mistake.

Reason for Upgrade:

I was backing up all my DVDs to a USB hard-disk as ISOs & then extracting as mp4 using Handbrake. There were far too many errors in the latest version supplied with Beowulf, and Chimaera offered a much later version. That proved to be fully correct after update.

Before Upgrade:

Pages consulted:

Since Chimaera was reported to be almost ready for transition to Stable, after consulting the above I decided that it should be possible to make a simple replacement in my existing sources.list of 'beowulf' by 'chimaera'. That was accurate except for the commented-out Chimaera line below.

Method of Upgrade:
~$ sudo nano /etc/apt/sources.list
~$ cat /etc/apt/sources.list
deb chimaera main non-free contrib
deb chimaera-security main non-free contrib
deb chimaera-updates main non-free contrib
deb chimaera-proposed-updates main non-free contrib
#deb chimaera-backports main non-free contrib

## package repositories
#deb beowulf main non-free contrib 
#deb beowulf-updates main non-free contrib 
#deb beowulf-security main non-free contrib 
#deb beowulf-proposed main non-free contrib  
#deb beowulf-backports main non-free contrib 

~$ sudo apt-get update && sudo apt-get dist-upgrade
Errors Experienced:

A single package (Libreoffice from Backports) gave a 404 File Not Accessible & the whole update collapsed in the middle. Unfortunately XFCE was in the middle of update & the GUI (including SLIM) failed after I tried restarting. Fortunately, I'm comfortable administering servers from a terminal.

The Fix:

This was easy once I got the point.

The problem was in a remote mirror connected with chimaera-backports. After commenting-out that line I did the update/dist-upgrade again (and again & again). The system complained, but gave some sensible suggestions, which I followed:

~$ sudo apt --fix-broken install
~$ sudo dpkg --configure -a

It's a heck of a business replacing a complete OS, of course, so I was patient and it finally completed.

The whole thing has gone from:

Devuan GNU/Linux 3.1 (beowulf) x86_64
Devuan GNU/Linux 4 (chimaera) x86_64

Good job, veteran Admins!

(updated (speling))

Re: Updating to Chimaera - Marginally Painless

Backports has been uncommented, resulting in LibreOffice updating to 7.2.1. The reason for that is that I appear to have done a customary system update just now exactly as Chimaera has gone from 'testing' to 'stable' (see the terminal results below):

A quick `sudo nano /etc/apt/sources.list`, remove the comment ('#') from backports & run the original update again, with dramatic results:

Re: Updating to Chimaera - Marginally Painless

I am curious about upgrading from 3.1 to 4. Will the OS update interfere with installed proprietary applications? (SoftMaker Office 2021, pdf Stuio Pro 2021).

Is there an instruction note on the main Devuan page on how to update?

I did install 4 on an old drive as wanted to see how the accessible speech install worked - outstanding!

Re: Updating to Chimaera - Marginally Painless

Hi there swarfendor437

I cannot answer for SoftMaker nor pdf Studio Pro, but my recall is that I got problems with a single installation, which was KeyMon (a python-driven utility which shows the keyboard keys pressed as you press them - very useful for YouTube videos if you are recording your desktop/terminal for YT).

The issue was the departure from Python2 to a base-standard of Python3 (all of this is off the top of my head & thus prone to errors). The repository-version of KeyMon could not run on python3 and thus KeyMon was not in Chimaera & wiped from my system on upgrade. Thankfully I found a github version by the original writer with specifically added python-3 support & it works fine.

For the rest I give the full instructions that allowed me to upgrade. So, either use that or refer to the links in the OP to bake it yourself.

Re: Updating to Chimaera - Marginally Painless

On the top of the forum page is a link to where you can find the official documentation and several howtos.

Myself I have upgraded my wifes PC and my file server from Beowulf to Chimaera without any issues. My PC is using parallel installation of Arch/Beowulf/Chimaera. I have moved my activities from Beowulf to Chimaera early summer this year before Chimaera even got stable.

General advice: disable any foreign repositories during the upgrade.
