There were only 3 broken packages but a lot of corrupted files.
$ LC_ALL=en_US sudo eopkg check | grep Broken | awk '{print $4}' | xargs sudo eopkg it --reinstall
Les paquets suivants vont être installés :
gnome-session libgnomekbd linux-current
I had some worrying messages (with PANIC term) but well it did the work.
I used LC_ALL=en_US
because it looks like it didn't work without.
Thank you Harvey 😃
