What is wrong?

conda deactivate

You installed an incompatible version of libstdc++ in your conda env, which overwrote the system version of libstdc++

4

May I know which version of libstdc++ is used in docker and how to check?
I will software link from conda to system.
I need to use conda to use other Python library.

5 
strings /lib/x86_64-linux-gnu/libstdc++.so.6 |grep LIB
6

I did software link to /lib/x86_64-linux-gnu/libstdc++.so.6 from conda environment.
