Ubuntu 17.10 reached End Of Life on 19th July 2018. You should have upgraded to 18.04 long ago.

Edit the file /etc/apt/sources.list, and change

fr.archive.ubuntu.com

to

old-releases.ubuntu.com

Then run:

sudo apt update
sudo apt upgrade

You should upgrade to 18.04 as soon as possible after that.
