PECL Install Error

Question

Hi, everyone.

I have followed this tutorial to install a PHP Zip extension: https://linux.how2shout.com/how-to-install-php-zip-module-on-amazon-linux-2023/

But when I run the command, sudo pecl install zip, I get the error.

No releases available for package "pecl.php.net/zip"
install failed.

I did tried to clear the cache command,

pear upgrade
pecl upgrade
pecl channel-update

however, the connection timed out every time.

Any help would be greatly appreciated. Thank you.

It works for me. This is with PHP8.2 that comes with AL 2023
```

Does your EC2 have IPv6 address assigned?

As per [Request #71308 	missing IPv6 support for pecl.php.net](https://bugs.php.net/bug.php?id=71308), it will not work if your EC2 instance has IPv6 address. 
```
sh-5.2$ sudo pecl install zip
Could not get contents of package "/usr/bin/zip". Invalid tgz file.
install failed
```

Answer

Is the instance in a public subnet? If it is in a private subnet, is there a NAT gateway to allow the request to reach the internet?
