Are you getting the following error while updating any package in pear?

pear.php.net is using a unsupported protocal – This should never happen.

I got this error right after I upgraded PHP from 5.2 to 5.9 (using CentOS-Testing repo). To resolve this situation, do this.

rm -fr /usr/share/pear/.channels

and then do this

pear update-channels

It should now give you the following output

Updating channel "doc.php.net"
Update of Channel "doc.php.net" succeeded
Updating channel "pear.php.net"
Update of Channel "pear.php.net" succeeded
Updating channel "pecl.php.net"
Update of Channel "pecl.php.net" succeeded

That’s it, your issue is resolved.
