I had the same errors for ResetDateTime.py. Appears to have been solved by editing the first line of the script to:
#!/usr/bin/env python2
Apparently the script is written for python2, while this docker defaults to python3 and it runs into compatibility issues. The edit above makes the script run under python2 and all is good again.
I'm new to the linux world and it's a steep learning curve, so please everyone let me know if I got this wrong.
It worked! Thanks again.
