Solutions

1. Check the preceding output lines for the per-plugin install failures.
2. Verify the plugin name or URL is correct and reachable from Jenkins.
3. Check network connectivity and update center configuration (Manage Jenkins > Plugins > Advanced).
4. Retry the install; use 'install-plugin <name> -deploy' to restart after installation.

When it happens

Trigger: Raised when the install-plugin CLI command fails while downloading or deploying one or more plugins. The underlying cause is printed earlier in the output.

Common situations: See trigger scenarios.
