Cannot upgrade and migrate to YunoHost 3

Hello,

My English may be approximate and i’m not a package management specialist.
Fisrt, i’ll try to execute the command given by APT

sudo apt --fix-broken install

Then try to install dependencies, update and upgrade

sudo apt -f install && sudo apt update && sudo apt dist-upgrade

And finally i’ll try to install packages with dependencies one-by-one trying the following one if the first one returns an error.

sudo apt install -f dovecot-core
sudo apt install -f dovecot-antispam
etc.

Thanks - your English is fine and far better than my French.
I tried the steps you mentioned (again) but to no avail.
I’ll reload my backup and try again from scratch.
thanks
