problems with update for ubuntu 17.10

what is the output of:

sudo apt-get update
sudo apt-get upgrade

Thanks

sorry , I didn't have time to try it out before today . I excuted the terminal and it tells me even the same .

We need the Terminal output itself, not your interpretation of the output...

Thanks.

I can't copy the error message but it says : "
toutes les mises à jour ne peuvent être installées
lancer une mise à jour partielle afin d'installer autant de mises à jour que possible
Ceci peut être dû à :
- une précédente mise à jour qui s'est mal terminée
- des problèmes avec un ou des logiciels installés
- des paquets logiciels non officiels qu'ubuntu ne fournit pas
- des changements normaux dûs à une version béta d'ubuntu
I try to do the "part upgrade" but it don't beginn.

Why can't you copy the output?

Please do these commands in a terminal window (to be opened by simultaneously pressing ctrl-alt-t)

In the menu of the terminal window there are entries "edit - select all" and "edit - copy" (or their French equivalent).

Please try again with the commands

uname -a
lsb_release -crid
LANG=C sudo apt-get update
LANG=C sudo apt-get upgrade
LANG=C apt list --upgradable

I can't copy the error message , I havn't any copy link when I try to right click
here are the results of the command :

the same error message appears when I want to update

There is a configuration error in the settings for the package management system.
You still have a reference to Ubuntu 14.10 which is not supported any more.

Please provide the output that you receive for the command

cat -n /etc/apt/sources.list

Did you upgrade from Utopic to Artful? If so, what method did you use?

for actionparsnip : I upgraded with the invite of ubuntu : it was the message of ubuntu which I followed. I upgraded from 17.04 to 17.10

I see two issues:

1. You have the repository artful-proposed enabled. The *-proposed repositories are used during testing, and the software there has in some cases turned out not behave as expected. (This is why there is a testing period before general roll-out.) If you are not involved in the testing of new packages, you should disable this repositors.
See also https://wiki.ubuntu.com/Testing/EnableProposed

2. You have two lines in your configuration file that refer to an older Ubuntu release (utopic instead of artful). It seems that this issue has already existed for a longer period.

My suggestion:
open a terminal window and issue the command
sudo gedit /etc/apt/sources.list
This will ask for your password as confirmation for an administrative action and then open an editor with the sources.list configuration file loaded.
Scroll down to he very end and put a comment indication ('#') at the beginning of the line that contains the word artful-proposed (line 52)

In the two preceding lines replace the word 'utopic' by 'artful'.
Save the file and close the editor.

Finally re-run the commands

sudo apt update
apt list --upgradable

and copy/paste the output into this question document.

Sorry, my fault. I forgot to add a command that is necessary when doing this in a wayland session (which is the default in Ubuntu 17.10 and later).

Try again with the commands:

xhost +si:localuser:root
sudo gedit /etc/apt/sources.list

The do the modifications as instructed before, save the file and close the editor.

and then issue the commands

xhost -si:localuser:root
sudo apt update
apt list --upgradable

and finally copy/paste the output into this question document.

at first : the output of the first part
