Continuous error loop after test completed #931
Comments

Interesting... really should be defined as per
https://docs.python.org/3/library/datetime.html#datetime.date.fromisoformat
-- it says since Python3.7
At the beginning of the run log or something it should indicate what
version of Python it's running... but I'm having a hard time imagining how
it would be <3.7...

Python 3.6 is default of Ubuntu 18.04, which I was running. When you run the cmd/build function, it throws an error and prompts an override command to build at this version, which I did. I upgraded python to 3.8 and rebuilt the environment and haven't seen the issue come back yet but it wasn't 100% of the time with 3.6 either so it's hard to say if it's fully resolved. Upgrading to python 3.8 on ubuntu 18.04 does break some other core packages (netifaces, netplan, pyyaml) so it's a bit of a headache to get it stable after the upgrade. |

Ah, I think what we might need to do is more specifically stipulate the
base Ubuntu/Python version. Some systems we're working with are up to
Ubuntu 20 and Python 3.9, and maintaining the system across all versions
can be problematic. Is there something pinning you to 18.04, or is that
just "what you had" (because at one point it was the latest).

Base image I built when it was the latest to rebuild the OS and VM whenever I had to due to corruptions or any other catastrophic loss. Nothing specifically pinning me there. Sounds like an upgrade might be worth it. |

Just started seeing a new issue show up. The tests run fine and the report is generated but then DAQ gets into this weird loop and never finishes.
