how to use rig behind proxy server

[ssh352]

how to use rig behind proxy server, wget works without issue. I have https_proxy and http_proxy env variables set.

❯ rig add release

rig does use the https_proxy env var for me (Ubuntu Linux):

root@7ee1366b84ee:~# export https_proxy=https://example.com
root@7ee1366b84ee:~# rig resolve release
[ERROR] Failed to resolve R version: Cannot download JSON: error sending request for url (https://api.r-hub.io/rversions/resolve/release/linux-ubuntu-22.04/aarch64): error trying to connect: unsuccessful tunnel

Just tried it with a proper squid proxy, on macOS, and that works as well, rig uses the proxy for HTTPS urls. Also, from your error

dns error: failed to lookup address information

hints that this is not an issue with rig, but there is something wrong with name resolution.

I am going to close this now, but if you still think that this is a rig issue, then please reopen with new information. Thanks!

sudo doesn't have proxy env variables set. Thanks!

[gaborcsardi]

Aha, that makes sense and we should indeed fix it. Thanks for the report!

This is fixed on GitHub. A workaround until the next rig version is released is to run sudo manually (with passing the env vars) and then running rig as the root user.
