When I install SDK from xds-cli command as follow, but it is fail.

xds-cli sdk install 5199b394
Installation failed (cannot init SetupFile path)

I use xds-server in Docker [1], and xds-cli by CUI.
SDK is copied into /xdt/sdk/poky-agl/ in docker, but xds-cli shows "SDK is not installed".

[environment]
xds-server side:
Docker container :
TAG : 5.0
IMAGE ID 75d0a72dbb72

xds-agent/cli side:
Ubuntu 16.04 (I use aws server)
install xds app by apt-get [2]
[log]
