I just upgraded to 6.6.3 and installed FCP and ran a diagnostics. It is showing an error for me saying "Rootfs file is getting full (currently 99& used). Not sure why I am getting this now. I don't have docker enabled. Attaching my diagnostics..

I am getting an error (marked in Red in the attached image). I was trying selecting the stable release from the internet and also tried local zip for v.6.6.3 and both the times got the same error. Any idea?
