I installed using helm on the CLI, but I also use rancher to manage this cluster. Is that possible to upgrade longhorn from the rancher UI?

it shows very different version numbers

I think our installation of longhorn is not clean at all. I see that the containers are using

image: longhornio/longhorn-manager:master-head

!!! That was in the longhorn.yaml file that was used for installation a long time ago. I'd rather run a specific version such as 1.4.3, or I guess now I may have to consider 1.5.1 directly if some stuff are already running newer code.
