When you did the upgrade to 18.10, in some cases, it changed working repository locations, to locations looking for repositories compatible with cosmic. Not all repositories have cosmic compatible files, hence the error.

For each error, go to the http:// location, like:

http://ppa.launchpad.net/ubuntu-wine/ppa/ubuntu/

and then click on the dists link, and view what the latest supported Ubuntu version is listed... in this example, it would be xenial (not cosmic).

Open the Software & Updates app, go to the Other Software tab, and change the Wine properties from cosmic to xenial. When you've made all of the changes, close the window, and click the Reload button to update the software databases.

Update #1:

In terminal...

cd /etc/apt/sources.list.d      # change directory
grep -i nvidia *.list           # find out which filename to edit
more nvidia.list                # view the correct found fileneme
# check the http web site as per my earlier instructions and
# determine the most recent Ubuntu version (if it isn't cosmic)
sudo pico nvidia.list           # put in the proper found filename to edit
sudo apt-get update             # you may have errors here if you didn't fix the other errors
sudo apt-get install dkms nvidia-dkms-390 nvidia-utils-390 # install
reboot                          # reboot the computer

  • thanks for the help brother.

    Also if you can help me with setting up nvidia drivers, would be great. I already installed the 390 driver for my gt 820m which it supports but I am not sure how to switch to nvidia card while I run a game.

  • @Dominator I don't know much about switching video cards. I know there's a CLI command to do it, but there must be something in the GUI to do it too. Go ahead and start a new question and see if you can get more help. Cheers. – heynnema Oct 24 '18 at 13:52
  • Hey is it possible to change that through terminal (cosmic to xenial). I messed up with nvidia and I cant install it again from terminal due to it being cosmic ppa. Can't see the gui, black screen. – Mahad Ansar Oct 24 '18 at 15:02
  • Yes, use the terminal, and ... oh, let me just update my answer... much more readable... give me a few minutes... – heynnema Oct 24 '18 at 15:44
  • How to do it from terminal, can you tell me command please – Mahad Ansar Oct 24 '18 at 15:50
