I did update from ubuntu 19.10 (it works there) It is issue with my machine?

$ uname -a                                  
Linux computer 5.4.0-29-generic #33-Ubuntu SMP Wed Apr 29 14:32:27 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

Thank you

Ok, i figure it out.

17 Makefile: unsupported SUBDIRS= replaced by M=
