Comment (by dd32):

 A non-zip currently errors out with the following message, which is pretty
 terrible, I agree.
 {{{
 The package could not be installed. PCLZIP_ERR_BAD_FORMAT (-10) : Unable
 to find End of Central Dir Record signature
 }}}

 The error outlined in the ticket here, {{{Abort class-pclzip.php : Missing
 zlib extensions}}} occurs when the PHP installation is missing both
 `ZipArchive` support, and doesn't contain `gzopen()` (ie. missing zlib
 extension, or that ubuntu bug #30213). In this case all update-related
 functionality doesn't work, and we don't appear to check support properly.
