| What's the fix? with a new . jenkins instance I have no option on the UI to downgrade. I tried manually installing but it does not work: ``` $java -jar /tmp/jenkins-cli.jar -s http://127.0.0.1:8080/ install-plugin https://updates.jenkins-ci.org/download/plugins/ec2/1.45/ec2.hpi Sep 27, 2019 3:51:31 PM org.apache.sshd.common.util.security.AbstractSecurityProviderRegistrar getOrCreateProvider INFO: getOrCreateProvider(EdDSA) created instance of net.i2p.crypto.eddsa.EdDSASecurityProvider Installing a plugin from https://updates.jenkins-ci.org/download/plugins/ec2/1.45/ec2.hpi ERROR: Unexpected exception occurred while performing install-plugin command. java.util.zip.ZipException: error in opening zip file ``` |
