I cannot use screenshots, I am writing on another computer - my ubuntu system is BLACK screned.
Yesterday I made an update to the new Ubuntu and this morning, the screen was turned black .
I received the following error
E: Error: BrokenCount > Orun-parts: /etc/update-motd.d/90-updates-available exited with return code 255 on the command lines screen. I found a lot of informations on your website and tried ; update, upgrade, configure, with --fix-missing, with option-f .... something happens with some package in the www.ubuntu archives.
Now, after one hour trying to do that, the message after
sudo dpkg --configure -a is stopped because more errors
sudo apt-get install -f, I receive a very long message (I will try to write here (it is mixed french))
Err:1 http://ch.archive.ubuntu.com/ubuntu xenial/main amd64 signon-ui-x11 amd64 0.17+16.04.20151125-Oubuntu1 Ne parvient pas à résoudre "ch.archive.ubuntu.com"
It proposes to try with
apt-get update (I did) or try
--fix-missing (I did)
So i have no result - Do you have an idea ???
