If you’re trying to install the MongoDB extension for PHP using PECL and encounter the following error:

You’re not alone. This is a common issue, especially on older systems or when PECL’s channel list is outdated.

Cause of the Error

This error typically occurs when:

• The PECL channel list on your server is outdated or corrupted.

• There are network issues preventing PECL from fetching the latest package list.

• You’re on a deprecated OS or PHP version where PECL defaults no longer align with current repository paths.

Quick Solution

You can often fix this issue by updating the PECL channel first:

sudo pecl channel-update pecl.php.net

This command forces PECL to refresh its channel list, downloading the latest available package information.

After that, try installing again:

pecl install mongodb
