At the /etc/apt/sources.list.d directory: What does .distUpgrade really mean?

Ubuntu

Hello

At the /etc/apt/sources.list.d directory exists the following files

docker.list              git-core-ubuntu-ppa-focal.list              google-chrome.list
docker.list.distUpgrade  git-core-ubuntu-ppa-focal.list.distUpgrade  mysql.list

What does .distUpgrade mean?

I assumed it was because through Virtual Box I did do an upgrade from Ubuntu 20.04 to 22.04 but why for mysql.list does not exist the mysql.list.distUpgrade file? Same for case google-chrome.list file

Now more, about docker the files content are equals

cat docker.list
deb [arch=amd64 signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu   focal stable

cat docker.list.distUpgrade 
deb [arch=amd64 signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu   focal stable

But is not the same for git

cat git-core-ubuntu-ppa-focal.list
# deb http://ppa.launchpad.net/git-core/ppa/ubuntu jammy main # disabled on upgrade to jammy
# deb-src http://ppa.launchpad.net/git-core/ppa/ubuntu focal main

cat git-core-ubuntu-ppa-focal.list.distUpgrade 
deb http://ppa.launchpad.net/git-core/ppa/ubuntu focal main
# deb-src http://ppa.launchpad.net/git-core/ppa/ubuntu focal main

Goal

Do an upgrade about focal to jammy and I found this situation

For mysql was easier (already upgraded)

cat mysql.list 
### THIS FILE IS AUTOMATICALLY CONFIGURED ###
# You may comment out entries below, but any other modifications may be lost.
# Use command 'dpkg-reconfigure mysql-apt-config' as root for modifications.
deb http://repo.mysql.com/apt/ubuntu/ jammy mysql-apt-config
deb http://repo.mysql.com/apt/ubuntu/ jammy mysql-8.0
deb http://repo.mysql.com/apt/ubuntu/ jammy mysql-tools
#deb http://repo.mysql.com/apt/ubuntu/ jammy mysql-tools-preview
deb-src http://repo.mysql.com/apt/ubuntu/ jammy mysql-8.0

Here for Google

cat google-chrome.list 
### THIS FILE IS AUTOMATICALLY CONFIGURED ###
# You may comment out this entry, but any other modifications may be lost.
deb [arch=amd64] https://dl.google.com/linux/chrome/deb/ stable main

Nothing to upgrade (nothing about either focal or jammy), not sure how common is this

Hi @Manuel_Jordan ,
I admire the way you inspect your filesystem after doing something. It is good practice… Everyone should do it.

Thanks for the polite and kind words …

I always do a research about a topic (question/answer) in 2 networks, I did do realize the answers are not always the same and thus each answer complements each other

I am always carefully with Linux OS. It is crucial and be taken all the points in consideration prior to apply any modification

Maybe that’s why I encounter problems here and there. I obediently listen to the Update Manager. If it asks for something then I give it. lol
