Cristian Uroz added a comment - 2017-02-10 06:41 After checking https://github.com/jenkinsci/jenkins/blob/jenkins-2.32.2/core/src/main/java/hudson/model/UpdateCenter.java#L846 I discovered the problem is in JENKINS_HOME/hudson.model.UpdateCenter.xml. For some reason, default site url is blank and "Load" function will not check correctly as it is only checking for default ID existance and no checking further if URL is default one or at least not blank or well-formed. Workaround/Solution: Add default update site http://updates.jenkins-ci.org/update-center.json in JENKINS_HOME/hudson.model.UpdateCenter.xml

ikedam added a comment - 2017-02-11 11:01 sharathinfy "id=simpleupdatesite" means this is an issue of SimpleUpdateSite plugin . I could reproduce the issue. Uninstalling SimpleUpdateSite plugin and restarting Jenkins resolved the issue. I changed the component/s to simpleupdatesite-plugin.

ikedam added a comment - 2017-02-11 11:03 cjuroz Broken hudson.model.UpdateCenter.xml can cause any issue. I couldn't reproduce the issue with Jenkins 2.32.2 with updatesites-manager plugin, and I'm not sure it's actually related to updatesites-manager plugin. Please create a new ticket when you find the cause.

Cristian Uroz added a comment - 2017-02-11 11:18 ikedam The error is not related with this plugin. It is having hudson.model.UpdateCenter.xml url for default site blank (or with a malformed url). If you want to reproduce this error just keep deafult site in that file but with an empty url. As I pointed before here: https://github.com/jenkinsci/jenkins/blob/jenkins-2.32.2/core/src/main/java/hudson/model/UpdateCenter.java#L846 Load function will scan for default site inside hudson.model.UpdateCenter.xml and if it cannot find it, will create one. If default site already exist, load function will not check further if url is valid or at least not empty.

ikedam added a comment - 2017-02-11 12:23 cjuroz The problem is what made the url empty. If it occurs with some specific opearations on Jenkins GUI, it should be fixed as a bug. Let me know if you secceeded to find the steps to reproduce it.
