Hello.
I think the way `cargo` uses `libcurl` is preventing it from looking
in the `CURL_CA_BUNDLE` environment variable to find where the
certificate authority file is.
Here we see what `cargo` I am using:
sebboh@geeks ~/projects$ cargo -V
cargo 1.36.0
Here we see the contents of one of my environment variables:
sebboh@geeks ~/projects$ echo $CURL_CA_BUNDLE
/home/sebboh/.guix-profile/etc/ssl/certs/ca-certificates.crt
Here we try to use `cargo` for a common task:
sebboh@geeks ~/projects$ cargo install rustfmt-nightly
Updating crates.io index
error: failed to download from
`https://crates.io/api/v1/crates/rustfmt-nightly/1.4.5/download`
Caused by:
[60] SSL peer certificate or SSH remote key was not OK (server
certificate verification failed. CAfile: none CRLfile: none)
Here we see that `curl` itself (from `guix install curl`) works fine
(some lines omitted for brevity).
sebboh@geeks ~/projects$ curl -v
https://crates.io/api/v1/crates/pkg-config/0.0.1/download
* Trying 34.202.125.55:443...
* TCP_NODELAY set
* Connected to crates.io (34.202.125.55) port 443 (#0)
* found 153 certificates in
/home/sebboh/.guix-profile/etc/ssl/certs/ca-certificates.crt
[...]
< HTTP/1.1 302 Found
[...]
* Connection #0 to host crates.io left intact
Now what? :)
Please note that I freshly installed `rust:cargo` and did not modify
anything, so maybe our guix package should be updated so it works out
of box. (Granted I think the TOFU principle for CA certs might be
better but, I guess that is not the topic today.)
Thanks, cheers,

This was discussed recently on IRC:
http://logs.guix.gnu.org/guix/2019-08-29.log#102010
Unfortunately we didn’t reach a conclusion.
My guess was that perhaps cargo honors a different environment
variable—i.e., not ‘SSL_CERT_FILE’, ‘SSL_CERT_DIR’, nor
‘CURL_CA_BUNDLE’. The ‘ltrace -e getenv’ trick I gave might give us
clues about relevant environment variables.
Could you give it a try?
Thanks,
Ludo’.

Ok, thank you. Unfortunately that user's pastebins expired so I was
not able to compare with my own `ltrace` output.

Ok, let's see:
sebboh@geeks ~$ ltrace -e getenv cargo -vv install rustfmt-nightly

I investigated this `OPENSSL_ALLOW_PROXY_CERTS` variable and I
concluded that I am not using any such cert--I believe in this case
libcurl checks an environment variable but would not act on the
result? Anyway, I don't use a proxy. (I just confirmed crates.io is
not on the blacklist at work.)
Well, I'm not sure what to check next. I can tell you that the values
of SSL_CERT_FILE and SSL_CERT_DIR seem to be correct (even though the
ltrace output truncates them).
Cheers, thanks,

Hi,
following nix (https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/compilers/rust/cargo.nix)
the right environment variable seems to be CARGO_HTTP_CAINFO
setting that to $SSL_CERT_FILE makes cargo work for me.
Cheers,
Robin
