You should install the SnapCenter Plug-ins Package for Linux by using the SnapCenter user interface (UI). If you cannot use the SnapCenter UI for some reason, you can install the SnapCenter Plug-ins Package for Linux either in console mode or in silent mode by using the command-line interface (CLI).
If the DISPLAY environment variable is set, you should run unset DISPLAY, and then try to manually install the plug-in.
For console mode installation, you must provide the required installation information while installing the SnapCenter Plug-ins Package for Linux. For silent mode installation, you do not have to provide installation information while installing the SnapCenter Plug-ins Package for Linux.
