I just installed Ubuntu 21.04 on dual-boot, but when i try to use sudo apt update i receive the following error:

I've tried many solutions but none of them worked. If I try to install any app like steam I get this:

Some packages could not be installed. This may mean that you have requested an impossible
situation or if you are using the unstable distribution that some
required packages have not yet been created or been moved out of

You have to fix broken repositories first by executing the following commands:

sudo add-apt-repository -r ppa:mc3man/xerus-media
sudo rm /etc/apt/sources.list.d/home\:strycore*.list

Then update package lists and install all needed upgrades by

sudo apt-get update
sudo apt-get install -f
sudo dpkg --configure -a
sudo apt-get dist-upgrade
