      Hi. I just fix Algorithm negotiation fail. Scp plugin does not work at new OpenSSH:

      ERROR: Failed to upload files

Build step 'Publish artifacts to SCP Repository' changed build result to UNSTABLE

      To fix this problem you need upgrade jsch library (i use 0.1.55). Put this jar to jenkins/plugins/scp/WEB-INF/lib/. Edit pom.xml from jenkins/plugins/scp/META-INF/maven/org.jvnet.hudson.plugins/scp/ and change version string to 0.1.55:

      <dependencies>
        <dependency>
            <groupId>com.jcraft</groupId>
            <artifactId>jsch</artifactId>
            <version>0.1.55</version>
        </dependency>
    </dependencies>

      Please update jsch lib to the lastest version. Thanks!
