Hi, I am trying to build the pdk on ubunto inside windows WSL, I cant get around this error: CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://conda.anaconda.org/symbiflow/linux-64/repodata.json>

In ubuntu WSL docker doesn't run. There is a problem of runlevel. Due to this problem docker service cannot be started. There are documentations on how to run everything without docker. You may follow that.

Yes, install Docker for Windows (which uses WSL). Then you can use it from Windows and also use it inside Ubuntu on WSL. Also I strongly recommend to not build the Tools by yourself but rather use a finished container, like ours: https://github.com/hpretl/iic-osic-tools Look at the quick start for designers. Just install a vcxsrv (X-Server) and you are good to go :)

Many thanks for your replies, thats exactly what I need
