volare enable remotedisconnected

[yihuajack]

I was running make of OpenLane in WSL 2 with all prerequisites satisfied including Docker. When it ran ./venv/bin/volare enable after creating a venv and upgrading volare in the venv, it seemed to wait for a few seconds and showed:

I tried to run the command in bash but it gives the same error. The connection to GitHub is proved to be of no problem. Are there any ways to know what happened and what caused this?

Hello Liu- not really sure, RemoteDisconnected means something may be up with your connection to GitHub. It could be that if you're sharing your IP with a whole bunch of people, GitHub is throttling connections. Mind you, this isn't as simple as loading a GitHub webpage, this is a relatively sustained 300 MB download.

To solve this problem, I would have to somehow make the download more resilient and/or enable people to download the .tar.xz themselves and just have volare import it.

For now, you can try volare build -j$(nproc) instead of volare enable, which will build the PDK from sources.

Thank you donn. It is true that my connection to GitHub was still problematic and very unstable. Now I changed to a completely "normal" network of educational network, and it works.
