Saw same issue. The cause is gcd is not supported by fractions anymore.

sudo vim /usr/lib/python3/dist-packages/xcbgen/align.py

And update

from fractions import gcd

from math import gcd

Works for me.

Exactly the same error here! No idea of how to go on.

I change the name of fractions.py in directory /usr/lib/python3.9 to fractions .pyc and copy fractions.py of directory /usr/lib/python3.8 to /usr/lib/python3.9 and run the conmands make -j$(nproc) and sudo make instal. After that i just delete fractions.py of directory /usr/lib/python3.9 and rename fractions.pyc to fractions.py of the same directory.

Thank you for your help.
