install error on ubuntu 18.04 zimbra 8.8.15

Hello I have this error installing the latest version (2.4.13) with installer 2.16.2

Downloading the ZAL library. It might take a few minutes ...
** GET http://openzal.org/2.7/zal-2.7-8.8.15.jar ==> 404 Not Found (1s)
404 Not Found at bin/get_zal.pl line 49.

I tried to download the jar directly from
http://openzal.org/2.7

This is the error:

404 Not Found
Code: NoSuchKey
Message: The specified key does not exist.
Key: 2.7
RequestId: 40659DB94A21A252
HostId: 34z88Ka/i7pDiTdORXNGlkra9Ozr+ps96i0378XlGSmEknKOPWQlNO6hM7AN74TGfkzyysHVpSs=

The latest accessible directory seem to be OpenZAL Binary File listing but is not compatible with 8.8.15

Best regards
