[CI][Docker] ubuntu_install_sgx.sh breaks when trying to download patch file

[leandron]

ubuntu_install_sgx.sh points to a patch file on a GitHub gist, which now seems to be removed. This makes the process of rebuilding the Docker images that invoke ubuntu_install_sgx.sh to crash.

This is the relevant line:
https://github.com/apache/incubator-tvm/blob/588523ddb6e938637d96745bcce145375307247f/docker/install/ubuntu_install_sgx.sh#L40

The repository name changed as well (probably not very relevant for the issue here), from https://github.com/baidu/rust-sgx-sdk to https://github.com/apache/incubator-teaclave-sgx-sdk.

I'm not very familiar with the Rust SGX SDK, that is why I'm asking: is this patch something we still need, or is it something that needs to be removed from the script?

hmm, I'll fix this now. SGX is unfortunately quite deprecated at this time (😬) and I think it reasonable to temporarily remove.

Update: apparently one can possibly recover a lost gist. I've followed the suggested answer and can only now wait. I hate breaking the build, so there's #4948, for expediency.

Thanks for fixing this, but I would suggest another issue to track the need for a proper fix for this?

Further, there is a this app[1], that uses ubuntu_install_sgx.sh, which in practice still depends on this GitHub gist and thus needs to be fixed as well. How do we not lose this information?
