I am an ubuntu user and after several hazard additions of external sources to my etc/apt/sources.list the software repositories files seem to be corrupted. I can no longer update without errors. I wonder how I can fix such a thing.
Here is my etc/apt/soure.list file and I have uubuntu 20.10
deb http://it.archive.ubuntu.com/ubuntu/ groovy main universe restricted multiverse
deb-src http://it.archive.ubuntu.com/ubuntu/ groovy main universe restricted multiverse
deb http://security.ubuntu.com/ubuntu groovy-security main universe restricted multiverse
deb-src http://security.ubuntu.com/ubuntu groovy-security main universe restricted multiverse
deb http://it.archive.ubuntu.com/ubuntu/ groovy-updates main universe restricted multiverse

deb http://it.archive.ubuntu.com/ubuntu groovy-backports main restricted universe multiverse
deb-src http://it.archive.ubuntu.com/ubuntu groovy-backports main restricted universe multiverse
deb http://archive.canonical.com/ubuntu groovy partner
deb-src http://archive.canonical.com/ubuntu groovy partner
When I run sudo apt-get update I got this.

I have to do a config and my apt must necessarily work well. It's been blocking me for a few days. I hope that someone can help me. Thanks.
Ubuntu 20.10 has been deprecated for nearly a year. You should replace it.archive.ubuntu.com with old-releases.ubuntu.com

After this is done, you should get back onto a supported version. Unfortunately, there's no way to do this anymore for ubuntu 20.10:
root@fd8c537092b2:/# apt-get install -y ubuntu-release-upgrader-core
...stuff...
root@fd8c537092b2:/# do-release-upgrade
...stuff...
An upgrade from 'groovy' to 'impish' is not supported with this tool.
There is a longer way to upgrade though, which is found here: https://help.ubuntu.com/community/EOLUpgrades/
To avoid this in the future, if you're not planning on upgrading your ubuntu OS every 6 months, you should stay on LTS releases. Otherwise be sure to upgrade soon after the next version is released so you do not end up running an unsupported release with a difficult upgrade path.
