Practically we have to access the server via attached wsl screen,
I tried installing on pure Ubuntu system it worked like a charm, yet again despite mapping the ports and changing index php my multi site network is not exposed.
It is there in OLS installation but inaccessible.
1) I am running docker on Windows with UBUNTU 18.04 WSL
2) We are unable to run the shell scripts like demosite.sh / : error--> shell script $' r' command not found
