    Try adding a ‘[trusted=yes]’ tag in your /etc/apt/sources.list (or sources.list.d/file) file at the line related to http://pkg.jenkins.io/debian-stable...

    At the end, in your souces.list file, you should end up with something like the following:

    deb [trusted=yes] http://pkg.jenkins.io/…..

    EDIT: this shell command should do the trick:

    sed -i 's/^deb /deb [trusted=yes] /' /etc/apt/sources.list

    then reload your apt cache with:

    apt update

    Hope it helps.

    Follow Jenkins Debian Packages for all the commands to install Jenkins in Ubuntu.

    1. Install Java
    2. Update your local package index
    3. sudo apt-get install jenkins

    I have installed it on Ubuntu 22.04.1 LTS and created a Video Tutorial of it.
