Jenkins has no installation candidate : error while trying to install jenkins on ubuntu system – Debian

so im trying to install the jenkins on my ubuntu and ofc i made sure to update the system by running : apt update

then i tried to run the following commands from jenkins website to install jenkins :

"


curl -fsSL https://pkg.jenkins.io/debian-stable/jenkins.io.key | sudo tee 

/usr/share/keyrings/jenkins-keyring.asc > /dev/null

echo deb [signed-by=/usr/share/keyrings/jenkins-keyring.asc] 

https://pkg.jenkins.io/debian-stable binary/ | sudo tee 

/etc/apt/sources.list.d/jenkins.list > /dev/null

sudo apt-get update

sudo apt-get install jenkins

then i got an error message that says :


Reading package lists... Done

Building dependency tree

Reading state information... Done

Package jenkins is not available, but is referred to by another package.

This may mean that the package is missing, has been obsoleted, or

is only available from another source

E: Package jenkins has no installation candidate

i barely understood, is that trying to recognize the repo which the files are downloading from?

i saw a youtube video of someone who had the same problem and he use the following commands:


wget -q -O - https://pkg.jenkins.io/debian-stable/... | sudo apt-get key add

'sudo sh -c 'echo deb https://pkg.jenkins.io/debian-stable binary/>/etc/apt/sources.list.d/jenkind.list

sudo apt-get update

sudo apt-get install jenkins

but it still doesnt work for me
can you help me please get jenkins installed ?

    switch to root user first.
    Command: sudo su –

    Then you can run the commands you ran earlier to install Jenkins. It should work now.

    You can add [trusted=yes] in the /etc/apt/sources.list.d/jenkins.list file.

    Initially /etc/apt/sources.list.d/jenkins.list will have,

    deb [signed-by=/usr/share/keyrings/jenkins-keyring.asc] https://pkg.jenkins.io/debian binary/

    Update it as,

    deb [trusted=yes] https://pkg.jenkins.io/debian binary/

    After that run the installation instructions.

    Eg: for Debian releases

    sudo apt-get update
sudo apt-get install fontconfig openjdk-11-jre
sudo apt-get install jenkins

    1. install ca-certificates.

      sudo apt install ca-certificates

    2. then install Jenkins from the official documentation

    I too had this problem and the issue was because I was using Zsh and not Bash. Once I switched to Bash (by typing "bash") the commands on the Jenkins website to install on Linux (Ubuntu for me) actually worked.

    first command
    1.

     curl -fsSL https://pkg.jenkins.io/debian-stable/jenkins.io-2023.key | sudo tee 
    /usr/share/keyrings/jenkins-keyring.asc > /dev/null

    Then add a Jenkins apt repository entry:
    second command:-

    echo deb [signed-by=/usr/share/keyrings/jenkins-keyring.asc] 
    https://pkg.jenkins.io/debian-stable binary/ | sudo tee 
    /etc/apt/sources.list.d/jenkins.list > /dev/null

    run these it worked for me

      sudo apt-get update
  sudo apt-get install fontconfig openjdk-11-jre
  sudo apt-get install jenkins
