Hi, I am trying to upgrade jenkins from 2.423 to the latest version and I am running into issues. I stop jenkins, I backup the jenkins war file, and I download the latest like so sudo wget [https://updates.jenkins.io/download/war/latest/jenkins.war](https://updates.jenkins.io/download/war/latest/jenkins.war) And then when i go start jenkins again I get an error "Job for jenkins.service failed because the control process exited with error code. See “systemctl status jenkins.service and journalctl -xe for details” I have upgraded jenkins version in the past and have never run into this issue, not sure why it’s doing this. Thanks Craig ---

Have you installed Jenkins with a package manager? If yes then you should also update Jenkins via the package manager and not by just updating the war file. Running `journalctl -u jenkins` should tell you what the problem is normally. Also 2.423 is a rather old version. The latest weekly version requires java17 did you consider this? I would also recommend to use LTS versions for productive systems. There you have upgrade guides that point you to important things you have to consider during upgrades. ---

Ah thank you, that helped greatly. Yes it appears I am still on java 11, upgrading that all currently. Good to know, i was able to find all the documentation on the LTS versions so ill be sure to do that. I used apt, so ill see if i can upgrade it with that ---

it appears I cannot upgrade jenkins through the package manager? its showing my installed version is 2.387.1 and that there is no newer versions to install? I did do an apt-get update and apt-get upgrade as well. sudo apt-cache policy jenkins jenkins: Installed: 2.387.1 Candidate: 2.387.1 Version table: \*\*\* 2.387.1 100 100 /var/lib/dpkg/status ---

oh i think i found my answer, had to run this to get the latest stable ```auto sudo wget -O /usr/share/keyrings/jenkins-keyring.asc \ https://pkg.jenkins.io/debian-stable/jenkins.io-2023.key 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 ```
