fatal: unable to access 'https://github.com/KhronosGroup/OpenCL-Headers.git/': OpenSSL SSL_read: Connection was reset, errno 10054

This error message indicates that there was a problem connecting to the remote repository on GitHub due to an SSL connection issue. There are several possible causes for this error, including network connectivity issues, firewall or proxy settings, or problems with the SSL certificate used by GitHub.

To resolve this issue, you can try the following:

1. Check your network connection: Ensure that you have a stable internet connection and that your firewall or antivirus software is not blocking the connection to GitHub. You can also try accessing the repository from a different network to see if the issue persists.

2. Clear your SSL cache: Sometimes, SSL cache can become corrupted, causing issues with SSL connections. Clearing the SSL cache can help resolve this issue. You can do this by clearing your browser cache, or by running the following command in your terminal:

$ sudo rm -rf /etc/ssl/certs

3. Disable SSL verification: You can try disabling SSL verification temporarily to see if it resolves the issue. However, this is not recommended as it can compromise the security of your connection. To disable SSL verification, you can use the following command:

$ git config --global http.sslverify false

4. Update Git to the latest version: Ensure that you have the latest version of Git installed on your system, as older versions may have issues with SSL connections.

If none of these solutions work, you can contact GitHub support for further assistance.
