			* Pacman does not work properly with our corporate certificate - https://github.com/msys2/MSYS2-packages/issues/4523

			----

			Another solution:

			Copy certificate of https://www.msys2.org/ to ca-bundle.crt file in C:\msys64\usr\ssl\certs

			Or something about:
			mv /mnt/c/msys64/usr/ssl/certs/ca-bundle.crt /mnt/c/msys64/usr/ssl/certs/ca-bundle.crt.orig

			Error:
			<pre>
			error: failed retrieving file 'clangarm64.db' from mirror.msys2.org : SSL certificate problem: self-signed certificate in certificate chain
			</pre>

			Export the necessary certificates from your browser:
			* Open https://repo.msys2.org in your web browser (Firefox, Chrome, Edge, etc.).
			* Click on the padlock icon in the address bar to view the site information and then view the certificate details.
			* Navigate to the certificate path or hierarchy and export all relevant certificates in the chain except for the final repo.msys2.org one (the intermediate and root CAs are what you need).
			* Save them as Base-64 encoded .pem or .cer files to a local directory on your Windows machine. You may need to ask your IT department for the certificates if you cannot export them.

			Import the certificates into the MSYS2 trust store:
			* Open an MSYS2 shell (e.g., MSYS2 UCRT64).
			* Place the downloaded .pem or .cer files into the C:\msys64\etc\pki\ca-trust\source\anchors\ directory (adjust the path if your MSYS2 installation is in a different location).

			Update the MSYS2 certificate trust:
			* In the MSYS2 shell, run the command:
			update-ca-trust

			Verify the fix:
			* Test the connection with curl:
			curl --fail --silent --show-error -I https://repo.msys2.org -o /dev/null && echo "OK!"

			pacman -Syu
