Hello, I recently upgraded by Debian version to Buster from Squeeze. Now my previously working Plone v5.2.3 instance will not run. How do I update my zinstance/bin/python2.7 so it is compatible with the one in Debian Buster? If it were a proper python virtualenv, I think I would know what to do, maybe it is, and I can use easy_install or pip to update it?
Below is my /bin/buildout output:
eric@bambu:~/Plone5/zinstance/bin$ ./buildout > /home/eric/error.txt

Here is my ./zinstance/bin directory (notice how old the python 2.7 is 2016!), and my new Debian Buster python 2.7 is recent (which is probably what's causing the mismatch):
