How to manually install the grafana-clock plugin

Thanks Graham.

But I am not on the sudoers list to use that command. But, I think I have 2 folders where plugins are present

  1. …/grafana/data/plugins/ and this is what is listed when we try and start the Grafana like below
INFO[02-04|13:54:37] Starting Grafana                         logger=server version=5.4.3 commit=6539180 branch=HEAD compiled=2019-01-14T09:26:26-0500
INFO[02-04|13:54:37] Config loaded from                       logger=settings file=...grafana/grafana/grafana-5.4.3/conf/defaults.ini
INFO[02-04|13:54:37] Config loaded from                       logger=settings file=..../grafana/grafana/grafana-5.4.3/conf/custom.ini
INFO[02-04|13:54:37] Path Home                                logger=settings path=...../grafana/grafana/grafana-5.4.3
INFO[02-04|13:54:37] Path Data                                logger=settings path=/..../grafana/grafana/grafana-5.4.3/data
INFO[02-04|13:54:37] Path Logs                                logger=settings path=/...../grafana/grafana/grafana-5.4.3/data/log
INFO[02-04|13:54:37] Path Plugins                             logger=settings path=/....../grafana/grafana/grafana-5.4.3/data/plugins
INFO[02-04|13:54:37] Path Provisioning                        logger=settings path=/....../grafana/grafana/grafana-5.4.3/conf/provisioning

So I am assuming ..../grafana/data/plugins/ is the plugin directory. So i unzipped the downloaded plugin zip here

But at the same time i also found that there is another folder where I can see all the installed default plugins and that is ..../grafana-5.4.3/public/app/plugins/datasource/ like in the below picture:

So, assuming this is the place where all the plugins are present, I tried to unzip here as well but even that does not work

So I am at a place where i am not sure what else can I try

Please look at my other doubt here: Druid plugin manual installation

leads are very much appreciatedd
Thanks
