I finally got to my main workstation with GUI, pulled the latest code, installed rofi there and it works now, I sill could not to get previews to show because of the draw_preview: command not found error. But I don’t think rofi can run on a headless machine:
<pre style="background-color:#ffffff;">
<span style="color:#323232;">rofi
</span><span style="color:#323232;">(process:1456958): X11Helper-WARNING **: 10:52:55.600: Failed to open display: (null)
