I setup openmediavault from scratch today and installed the kubernetes plugin.
openmediavault 7.6.0-1
openmediavault-k8s 7.4.3-1
After activating the plugin I tried to copy the token to clipboard. But it does fail with: Failed to copy data to the clipboard.
I tried with my own user and original OMV admin. Also rebooting the whole machine did not help.
Both binaries k3s and kubectl are available on CLI (via SSH).
