	java -version

Add Jenkins Repository

sudo wget -O /usr/share/keyrings/jenkins-keyring.asc https://pkg.jenkins.io/debian-stable/jenkins.io-2023.key

Next, add the Jenkins repository to your system’s sources.list:

sudo sh -c 'echo deb [signed-by=/usr/share/keyrings/jenkins-keyring.asc] https://pkg.jenkins.io/debian binary/ > /etc/apt/sources.list.d/jenkins.list'

sudo apt update

sudo apt install jenkins -y

If the software was installed incorrectly, you can reinstall it after uninstalling it first.:

sudo apt remove --purge jenkins

jenkins --version

Try run jenkins without service

sudo -u jenkins /usr/bin/jenkins --httpPort=8081 --httpListenAddress=0.0.0.0

sudo mcedit /lib/systemd/system/jenkins.service

sudo systemctl start jenkins &&
sudo systemctl enable jenkins &&
sudo systemctl status jenkins

sudo journalctl -xeu jenkins.service | tail -n 50

Если порт занят, проверяем кем:

sudo lsof -i :8081

Переопределяем порт:

sudo mcedit /etc/default/jenkins

HTTP_PORT=8081

sudo systemctl restart jenkins

start http://127.0.0.1:8081
