RIG 0.7.1 cannot find or does not use certificates

[mcanouil]

I'm behind a proxy, using WSL and had to add a certificate:

sudo cp /path/to/company.cer /usr/local/share/ca-certificates/company.crt
sudo update-ca-certificates

Unfortunately, this did not solve the issue with rig:

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-24.04/x86_64): error trying to connect: invalid peer certificate: UnknownIssuer

Note that curl works properly when checking the URL:

curl -v https://api.r-hub.io/rversions/resolve/4.4/linux-ubuntu-24.04/x86_64

To ensure rig was able to read the certificates, I had to do:

export SSL_CERT_FILE=/etc/ssl/certs/ca-certificates.crt
rig resolve release

Is there a way this (or similar) can be done automatically by rig?
