Hi there!
When I install tinytex, I get the following error - it seems to indicate that there is soemthing wrong with the SSL certificate to install tinytex?
I've tried
- updating homebrew
- using the dev version of tinytex on github
- restarting R each time
- restarting my machine
- different wifi connections
- running
curl -sL "https://yihui.org/gh/tinytex/tools/install-unx.sh" | shin terminal (I get the exact same error)
Any help + guidance to how I can fix this would be greatly appreciated!

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.
