Keep getting error for Python support

[mit10000]

Followed instructions here
https://github.com/QuantConnect/Lean/tree/master/Algorithm.Python#python-autocomplete-imports
OS: Ubuntu 16.04
Already installed dotnet-sdk-6.0, and we could do
dotnet build QuantConnect.Lean.sln
dotnet QuantConnect.Lean.Launcher.dll
and get STATISTICS. Seems C# is running OK.

Tried to use Python:
1 create new enviroment
conda create -n qc_lean python=3.6.8 cython=0.29.11 pandas=0.25.3 wrapt=1.11.2
2 add new line to /etc/environment
PYTHONNET_PYDLL="/home/myname/anaconda3/envs/qc_lean/lib/libpython3.6m.so"
3 change Lean/Launcher/config.json
"algorithm-type-name": "BasicTemplateFrameworkAlgorithm",
"algorithm-language": "Python",//"CSharp",
"algorithm-location": "../../../Algorithm.Python/BasicTemplateFrameworkAlgorithm.py",
4 rebuild, rerun
dotnet clean
dotnet build QuantConnect.Lean.sln
dotnet QuantConnect.Lean.Launcher.dll
Then got ERRORS

After refer to
https://www.quantconnect.com/forum/discussion/4802/got-an-error-msg-when-running-python-on-desktop/p1
we tried to modify
Common/Python/Python.Runtime.dll.config
to

but still got the same errors

[mit10000]

The xml information didn't show in the last post:

dllmap os="linux" dll="python3.6m" target = "/home/myname/anaconda3/envs/qc_lean/lib/libpython3.6m.so"

Are you able to use the docker container-based LEAN CLI? This bypasses hundreds of dependency issues from conflicting / unsupported versions of libraries and packages. Sadly we're not able to provide support unless in a known environment combination. If you'd like a native installation, you could set it up like the Dockerfile does -- with all those package versions.
