I am having some problems with my repositories. It happened suddenly without I did anything and I cant understand why. I am running ubuntu 19.10. I tried many things like resetting my source.list or modifying the main server in the software-gtk application. WHen I change the server, I get a "refresh softwares" screen that leads to a ubuntu error. Afterwards, I cant access the software-gtk anymore. I cannot install anything anymore with the command apt-get install packagename. If I use aptitude and make an update: picture

Below you will find the result of sudo apt update (the end because otherwise it is too long):

And here is my source.list file:

deb [trusted=yes] http://archive.ubuntu.com/ubuntu eoan main universe restricted multiverse
deb-src [trusted=yes] http://archive.ubuntu.com/ubuntu eoan main universe restricted multiverse #Added by software-properties
deb [trusted=yes] http://security.ubuntu.com/ubuntu/ eoan-security main universe restricted multiverse
deb-src [trusted=yes] http://security.ubuntu.com/ubuntu/ eoan-security main universe restricted multiverse #Added by software-properties
deb [trusted=yes] http://archive.ubuntu.com/ubuntu eoan-updates main universe restricted multiverse
deb-src [trusted=yes] http://archive.ubuntu.com/ubuntu eoan-updates main universe restricted multiverse #Added by software-properties

I do not know what to do as I would like to avoid reinstalling the system... Any idea of what is happening? Thanks in advance for your help.

Ubuntu 19.10 is End Of Life - https://fridge.ubuntu.com/2020/07/17/ubuntu-19-10-eoan-ermine-end-of-life-reached-on-july-17-2020/

It's recommended to upgrade to 20.04 https://help.ubuntu.com/community/FocalUpgrades

For ubuntu desktops the process is as follows

You can easily upgrade over the network with the following procedure.

Run the update-manager application;

In Update Manager, click the Settings... button, and enter your password to start the Software Sources application.

Select the sub menu Updates from the Software Sources application.
Confirm the "Notify me of a new Ubuntu version:" option is set to "For any new version" if you are using 19.10 or to "For long-term support versions" if you are using 18.04 LTS. If it is not set properly modify it the appropriate option.
Close the Software Sources application and return to Update Manager.

In Update Manager, click the Check button to check for new updates.

If there are any updates to install, use the Install Updates button to install them, then exit.

In a terminal run update-manager -c -d. 

Follow the on-screen instructions.

This site shows two possible processes : via software apps or via terminal commands in more detail : https://www.linuxbabe.com/ubuntu/upgrade-ubuntu-19-10-to-ubuntu-20-04
