module 'f5cli.utils' has no attribute 'core'

Error reproducible in Ubuntu 18.04 using Python3 with and without virtual environments. This is a lab inside the F5 Unified Demo Framework (UDF) so I can provide access if needed.

I was able to reproduce this issue on a customer's Ubuntu image today. Same error and version of Ubuntu.

[shyawnkarim]

Thank you for reporting this bug. I've filed a bug ticket for this. Internal ID AUTOSDK-298.

[jmacnett]

any word on this? did a fresh install on both centos 7 and centos 8 today w/o the vm solution, and im' seeing this same error for every command

[shyawnkarim]

We were able to duplicate this error with Python version 3.6.9. Updating to version 3.7.5 resolved the issue. Can you update your version of Python and let us know if you are still getting the same error?

[jmacnett]

centos boxes had issues w/ the python upgrade; however, I put python 3.7.3 on a WSL instance and it got past that particular error, at least, so it looks the versioning thing is probably pretty accurate in terms of what's happening there.

Thanks.
