As in title i can't start jenkins service on ubuntu ec2 server. Fail message
Also its giving this warnings when i tried to "sudo apt update"sudo update warnings
i think problem is caused by gpg key but i dont understand whats happening.
I tried;
- update and upgrade apt's
- update java
- delete and reinstall jenkins
I just want to deploy my Java backend project on ec2. So i want to use jenkins on my aws server.
