Solution

  • You have mixed sources.list. You are on jammy but you have impirish sources.list.

    Open the terminal and type:

    sudo gedit /etc/apt/sources.list

    Remove all inside and paste this:

    deb http://in.archive.ubuntu.com/ubuntu/ jammy main universe restricted multiverse
deb-src http://in.archive.ubuntu.com/ubuntu/ jammy main universe restricted multiverse
deb http://security.ubuntu.com/ubuntu jammy-security main universe restricted multiverse
deb-src http://security.ubuntu.com/ubuntu jammy-security main universe restricted multiverse
deb http://in.archive.ubuntu.com/ubuntu/ jammy-updates main universe restricted multiverse
deb-src http://in.archive.ubuntu.com/ubuntu/ jammy-updates main universe restricted multiverse

    Then run:

    sudo apt-get update
