netclient-install.sh failed

[changchichung]

OS: ubuntu 20.04 x64

netclient is a folder already exists , so the script won't get the netclient binary.

chchang@dc039:~/git/netmaker$ curl -sfL https://raw.githubusercontent.com/gravitl/netmaker/v0.1/netclient-install.sh |SERVER_URL=ws.abc.com:50051 NET_NAME=TEST_VPN KEY=abcdefg sh -
netclient: 是個目錄 <---it means netclient is a folder 

so I temporary rename the netclient folder and run the install script again , but there are some other error messages

chchang@dc039:~/git/netmaker$ mv netclient netclient.bak
chchang@dc039:~/git/netmaker$ curl -sfL https://raw.githubusercontent.com/gravitl/netmaker/v0.1/netclient-install.sh |SERVER_URL=ws.abc.com:50051 NET_NAME=TEST_VPN KEY=abcdefg sh -

I know the reason why the script failed to establish a vpn connection.
I created a network named "test_VPN" (watch the capitalization)

but the name shows all in capitalization everywhere.

so I misunderstanding the network name , after fix the name to correct one , it's ok now to run the script without error
