For new installs of management pack builder, we recommend installing version 1.1.2.
If upgrading from version 1.0.0, it is recommended to upgrade directly to version 1.1.2.
If you started a 1.1.0 install or upgrade and it failed, follow these instructions clean up the failed install:
1. SSH into the Management Pack Builder virtual machine
2. Remove the db and secret.json files
rm -rf /opt/vmware/data/db /opt/vmware/conf/secret/secret.json
After the db and secret.json files have been removed, you can proceed to upgrade to version 1.1.2
