Issue with Installing GNURadio Satnogs on Linux 20.04.02

Hello,

I am following this intruction for installation of satnogs: Ubuntu - Client Installation - SatNOGS Wiki

I removed gnuradio that previously installed but, I am keep getting GrSwig not found error:

GrSwig

– Configuring incomplete, errors occurred!

What could be the issue here I have?

I tried installing GrSwig individually, but not working.
