Can you provide any more suggestions of the steps you took that caused the issue to appear?

Have you seen this again since the original time?

i am also same error in Jenkins Plugins updates page in Linux OS. Jenkins ver - 2.263.1

When i click on "Download now and install after restart" button, i am getting this error!

Can you pls help me to resolve this error? Thank you.

When i try to update plugin from  https://jenkins.xx.com/pluginManager/advanced

I am getting same error as above for both updatesite with url or Upload plugin with downloaded plugin file!

markewaite:

devops_1 the setting for the URL of the update center is wrong. You provided the URL to a single plugin. The Jenkins instructions at updates.jenkins.io say that it should be https://updates.jenkins.io/update-center.json. Use the correct update center URL and it should resolve the issue.

In general, please use the mailing list or the chat channels to request help. Using an issue report significantly limits the number of people who will read your request and may cause you to receive no responses.

Thank you so much for your help, yes, that resolved my issue, that was the culprit, not sure why it was sticky there, we used it one time to update that plugin.

thank you.
