Comment (by dd32):

 Replying to [comment:2 dd32]:
 > 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.

 Small clarification: If the install has `ZipArchive` support, but no
 `gzopen()` available, and a non-zip is uploaded, it'll also hit the above
 conditional, which is currently wrapped in a `die()`
