There were more files and I ran
sudo apt-get autoremove --purge
Then
apt-mark showmanual | grep -E "linux-.*[0-9]" | grep -v "hwe" | xargs -r sudo apt-mark auto

And again
sudo apt autoremove --purge -y

Seems to have deleted a couple files.

Well I installed it in the common way I'd say : USB drive, erase all disk and install encrypted version with LUKS. I connected to a wifi network during the installation.

Then I ran the following commands to reinstall the packages I had on my previous computer (attached file) :
sudo apt-get update
sudo apt-get install dselect
sudo dselect update
sudo dpkg --set-selections < liste-des-paquets
sudo apt-get -u dselect-upgrade
(I've been doing this a couple times from previous systems, starting in 20.04, now I'm in 20.04.3).

Do you see what happened ?
Thanks
