Hi,

I am running jenkins in corporate network, where i am trying to install/update jenkins. (downloading .hpi and then uploading)

But installation is not happening after succesfull upload and failed with below reason.

Hi,

this looks like a dependency can not get installled., probably due to jenkins not seeing the update center. So you need to manually upload all dependencie before your plugin.
