I am a beginner looking to learn basics of Haskell before my first term at university. I recently installed GHCup for Haskell (mac) using the terminal window command
curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | sh
However, it gave me this error:
curl: (60) SSL certificate problem: certificate has expired
More details here: https://curl.haxx.se/docs/sslcerts.html
curl performs SSL certificate verification by default, using a "bundle"
of Certificate Authority (CA) public keys (CA certs). If the default
bundle file isn't adequate, you can specify an alternate file
using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
the bundle, the certificate verification probably failed due to a
problem with the certificate (it might be expired, or the name might
not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
the -k (or --insecure) option.
HTTPS-proxy has similar options --proxy-cacert and --proxy-insecure.
It shows that my SSL certificate has expired, is there a way I can fix this? My version is a mac High Sierra 10.13.6 and GHCup seems to be compatible with 10.13>, so I'm not really sure...
