I get this error when starting Jenkins: Jenkins initial setup is required. An admin user has been created and a password generated.

I can fix it by adding and uncommenting this line in /etc/conf.d/jenkins: # # Options to pass to java when running Jenkins. # JENKINS_JAVA_OPTIONS="-Djava.awt.headless=true" #JENKINS_JAVA_OPTIONS="${JENKINS_JAVA_OPTIONS} -Dhudson.DNSMultiCast.disabled=true"
Thanks for the bug report. Which version are you trying to install please?
(In reply to Patrice Clement from comment #2) > Thanks for the bug report. Which version are you trying to install please? dev-util/jenkins-bin-2.12
OK. By the way, I think you can also switch the "true" flag here: -Dhudson.DNSMultiCast.disabled=true to "false" to get to the same result.
Is this still an issue with recent versions of jenkins-bin?
