When trying to install composer, why is Ubuntu unable to find the openssl package?

edit

Ubuntu may be unable to find the openssl package because it is either not installed or not available in the current repository list. It is recommended to update the repository list and ensure that openssl is installed on the system before installing composer. You can use the following commands to install openssl and update the repository list:

1. sudo apt-get update
2. sudo apt-get install openssl

After installing openssl, you should be able to install composer without any issues.
