Hi,

while trying to run a simple R script on my guix server, I stumbled upon
a problem with HTTPS and R. It's nothing urgent...

reproducer.R
library(jsonlite)
library(tidyverse)
library(lubridate)
api_parking <- "https://guix.gnu.org/packages.json"
parking.raw <- fromJSON(api_parking, simplifyDataFrame = TRUE)

$ R CMD BATCH reproducer.R
[...]
> library(jsonlite)
> library(tidyverse)

Attaching package: ‘lubridate’

The following object is masked from ‘package:base’:

    date

> api_parking <- "https://guix.gnu.org/packages.json"
> parking.raw <- fromJSON(api_parking, simplifyDataFrame = TRUE)
Error in open.connection(con, "rb") :
  server certificate verification failed. CAfile: none CRLfile: none
Calls: fromJSON ... parse_and_simplify -> parseJSON -> parse_con -> open
-> open.connection
Execution halted

For the record my SSL/HTTPS related variables.
$ echo $SSL_CERT_DIR
/etc/ssl/certs
echo $SSL_CERT_FILE
/etc/ssl/certs/ca-certificates.crt
echo $CURL_CA_BUNDLE
/run/current-system/profile/etc/ssl/certs/ca-certificates.crt

All required packages (r, r-*, nss-certs) are installed system wide.

Regards Jonathan
