I started a fresh container from jenkinsci/blueocean docker image in my Ubuntu 16.04 LTS server. Container started fine and I am able to see Jenkins console perfectly. When I am trying to install any plugin which isnt bundled with this image it is giving SHA-256 mismatch error like below:-

java.io.IOException: Downloaded file /var/jenkins_home/plugins/build-pipeline-plugin.jpi.tmp does not match expected SHA-256, expected 'Ci0bq1rxqEDWF1RklJvBZANp75727gH13+5cFr5HDbs=', actual 'c0qvGjbwCXYFueMfd77NFvIfRPG21Dxt4OxbZ+Gc/7c='

This is happening with all the plugins I am trying to install or update. I googled about it but couldn't get anything constructive.

I also installed Jenkins as standalone in the server but I am getting the same error again, which seems that it could be related to my server itself.

I was thinking to install plugins as well while the container is built through the Blue Ocean or Jenkins official image to make everything go as a code, but it seems I'll end up with the same issue.

Can someone help me to resolve it or find an alternative way to install plugins?
