I have been trying to download MSYS2 but have run into quite a few errors. I would like to try out some C++ development so wanted to download it onto my windows 11 laptop. By following the instructions found here, I selected the vscode option on the Start Menu shortcuts (using the installation wizard). When I got to step 6, it came up with these errors (cut down for Overflow's character limit):
error: failed retrieving file 'mingw-w64-ucrt-x86_64-gcc-13.1.0-6-any.pkg.tar.zst' from mirror.msys2.org : SSL certificate problem: self-signed certificate in certificate chain

And so on...
When addressing this issue, I found this stack overflow page and this FAQ question (Q2). However, it came up with this new error when I did the curl command:
$ curl --fail --silent --show-error -I https://repo.msys2.org -o /dev/null && echo "OK!"
curl: (60) SSL certificate problem: self-signed certificate in certificate chain
More details here: https://curl.se/docs/sslcert.html
curl failed to verify the legitimacy of the server and therefore could not establish a secure connection to it. To learn more about this situation and how to fix it, please visit the web page mentioned above.
How can I fix this?
(Edit): The computer is on my school system so it is likely to go through an SSL interception proxy. Errors include:
(1) SSL certificate problem: self-signed certificate in certificate chain
(2) SSL connection timeout
(3) Could not resolve host: repo.casualgamer.ca
(4) OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to [website]:443
(5) OpenSSL/3.1.0: error:0A0003E8:SSL routines::reason(1000)
(6) Could not resolve host: [website]
It looks like you have some HTTPS man-in-the middle like a proxy or firewall doing SSL interception.
You can probably ignore this with the curl flag
