SSH into your jenkins instance and check if jenkins is running perhaps it might be "Stopped"

Had the same problem. This is because the /etc/apache2/sites-available/jenkins.conf needs to be updated with the new hostname.

Starting LSB: Start Jenkins at boot time...
ERROR: No Java executable found in current PATH: /bin:/usr/bin:/sbin:/usr/sbin

I stopped the instance and restarted it again but when I enter ec2 instance public dns in url page I am unable to access the jenkins page. always showing "Apache2 Ubuntu Default Page" how to reslove this issue.

tell me the GITHUB url where all the Maven java project code is stored ??

when we try to enter systemctl reload apache2
==== AUTHENTICATING FOR org.freedesktop.systemd1.manage-units ===
Authentication is required to reload 'apache2.service'.
Authenticating as: Ubuntu (ubuntu)
Password:
polkit-agent-helper-1: pam_authenticate failed: Authentication failure
because of this I am unable to access the jenkins with "aws ec2 instance name:8080" in my local browser.

can anyone please guide me to resolve this issue

Err:1 http://pkg.jenkins-ci.org/debian binary/ jenkins ...                               
  Connection failed
E: Failed to fetch http://pkg.jenkins-ci.org/debian/binary/jenkins_..._all.deb  Connection failed

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

If anyone facing the above error. Please use the following commands instead while installing Jenkins:

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

sudo rm  /etc/apt/sources.list.d/jenkins.list

echo "deb https://pkg.jenkins.io/debian-stable binary/" | sudo tee -a /etc/apt/sources.list.d/jenkins.list

sudo apt-get update

sudo apt-get install jenkins

If you still facing issues while installing Jenkins, you can directly download it from there website: https://pkg.jenkins.io/debian-stable/

Cheers!!
