Bug#950467: Maybe upgrading the cython3 package fixed it

[Kingsley G. Morse Jr.]

I'm happy to report I'm now looking at a cool 

    sage:

prompt.

Since the last error message also alluded to 
cython

> ImportError: /usr/lib/python3/dist-packages/sage/libs/gap/element.cpython-37m-i386-linux-gnu.so: undefined symbol: GAP_EnterStack_

I tried manually upgrading the cython3 package
from 0.29.2-2 to 0.29.14-0.1+b1.

I wish I were more confident I knew what actually
fixed it, but as a practical metter, it's OK with
me if you close this bug report.

So,
Kingsley
