Plugin issues

PMM cannot install, upgrade, or remove plugins

If you cannot install, upgrade, or remove plugins in PMM, check the permissions on the /srv/grafana/plugins directory.

When permissions are wrong, Grafana cannot write to the directory, which blocks all plugin operations.

Solution

To fix the permissions and restart Grafana, run the following commands:

1. Set ownership on the /srv/grafana/plugins directory to 1000:0, which is the UID/GID that PMM Server runs as:

   docker exec --user root pmm-server chown -R 1000:0 /srv/grafana/plugins
   

2. Restart Grafana to pick up the change:

   docker exec --user root pmm-server supervisorctl restart grafana
