Many users face this issue when they attempt to set up Composer for PHP dependency management. Fortunately, this is a common problem with a straightforward solution.

OpenSSL Library Version: OpenSSL 1.1.1f 31 Mar 2020

Native OpenSSL support: enabled

Installed PHP Packages

To ensure everything is arranged correctly, you can check the installed PHP packages on your system by running the command:

Conclusion

In summary, encountering an "unable to locate package php-openssl" error on Ubuntu is a common issue, but it's essential to recognize that PHP comes with built-in SSL support, and you do not need a separate package. By following the steps outlined above, you can confirm OpenSSL's presence in PHP and proceed with your Composer installation without any further issues.
