Comment 19 for bug 91399

usermoi@ubuntu:~$ sudo apt-get purge console-setup
Password:
E: L'opération purge n'est pas valable

meaning with a rough traduction purge operation is not valid

this other suggestion

sudo apt-get --purge remove console-setup

this will remove all the configuration files of console-setup. Then install
with:

sudo apt-get install ubuntu-minimal

doesn't give any error message (against what happened in the past)
and nice to see that console-setup is installed (during my tries I could remove console setup and of course after that nothing was complainning about error in consol-setup)

Thanks to all of you it looks fine now, you are marvellous
I can go sleeping it's enough for today ;-)
