Thanks for the test.

You might want to consider becoming a Mageia packager, so that you can push such fixes to 6/updates_testing :-)

Our zlib maintainer maintains way too many packages, I think he'd be happy to get a hand.

uploaded to 6/updates_testing ad subrel 1 / rel 4. Please test.

I can confirm that lib64zlib1-1.2.11-4.1.mga6.x86_64.rpm fixes the issue.
@Marja, sorry, I cannot commit to be a packager

Luca, maybe you can write an update advisory explaining what just got fixed and assign this bug to qa-bugs@ml.mageia.org, so the update can be released.

Updated packages:
libzlib1-1.2.11-4.1.mga6
libzlib-devel-1.2.11-4.1.mga6
libminizip1-1.2.11-4.1.mga6
libminizip-devel-1.2.11-4.1.mga6

from zlib-1.2.11-4.1.mga6.src.rpm

Whiteboard: (none) => MGA6-64-OK

I'll try:

zlib 1.2.11 breaks the gzip content compression in UniFi guest portal (tomcat server) and probably other java tools that rely on zlib.

This package applies a patch from upstream that fixes the issue.
