4. Extract tar.gz to /repository - tar xzf VMware-NSX-upgrade-bundle-yourversion.tar.gz -C /repository
5. Set proper permissions and ownership of the /repository files by executing the following - /opt/vmware/proton-tomcat/bin/reposync_helper.sh
6. Resolve the repo-sync failure on #.#.#.# node from UI.
