Hello everyone,
I am currently working on gnuradio 3.9 on ubuntu 18.04 and currently facing an error while creating an OOT module using the terminal which is shown as:
merlin@merlin:~/yash$ gr_modtool newmod packetizer
Creating out-of-tree module in ./gr-packetizer...
Traceback (most recent call last):

(result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xbf in position 4: invalid start byte
Hence, I want to resolve this issue as soon as possible.
Also, I am currently working on the project "'Implementation of a packet encoder/decoder pair in the GNU radio framework'".I am getting some serious errors while running the project on the above mentioned environment shown as:
