Prebuilt packages compatible with older OS

[pzelasko]

We’re facing some issues with pip and conda installed k2 packages on the CLSP grid since the GitHub actions CI upgraded Ubuntu to 18.04. The issue is that our Debian 4.9 system has glibc version older than 2.27. Could you prebuild and upload the packages for older systems like this? I can provide more info if needed.

GitHub actions does not support Ubuntu 16.04 anymore.

I have tried to use a docker image with Ubuntu 16.04 to build k2 with GitHub actions but it is failed with the following error message and I have no idea how to fix it.

That is weird, it looks like you’re trying to copy a directory into a sub-directory within that directory. Maybe there are some env vars or docker args related to workdir path that could be changed to amend this. But I never built any anaconda package so I wouldn’t know what they are..

I will try to fix it.

Thanks!
