Sometimes you may get this error while you try to install php modules using pecl command. and you may get the error “pecl.php.net is using a unsupported protocal” .

In case you get this error, clear out the contents in /usr/local/lib/php/.channels and /usr/lib/php/.channels and run the command ‘pecl update-channels’ . That should fix the issue.
