These are the 2 I have installed:

sudo apt search lz4

As you can see r131 is from 2015.

What is the output of:

apt-cache policy lz4

Ubuntu is taking over a part of its packages from Debian, and as far as I can see, in Debian there is already the newest version lz4 1.8.0-2, but only in experimental.

I assume that after a reasonable amount of testing and verification, this version will also be made available in Debian unstable and/or testing, and this is the moment that Ubuntu will also consider that package version for including in its development version. My guess is that this might be in Ubuntu 18.10 or 19.04

see also https://tracker.debian.org/pkg/lz4

Eventually you can find a PPA with this version (standard disclaimer for PPAs applies of course).

Alright I'll take this up with them.

Bryan (suprafreehand) said : #8

The package moved into 'unstable' now.


Thanks to Nobuhiro Iwamatsu for all the effort!

Bryan (suprafreehand) said : #9

The 1.8.1 package migrated from 'unstable' to 'testing'.


Now that it's part of Debian 10 will it be considered? Or will it have to make it to 'stable'?

Manfred Hampl (m-hampl) said : #10

I assume that it will be considered for the next Ubuntu release (18.10), but no more for 18.04 when published, because Debian import freeze was already six weeks ago.

Maybe an SRU makes sense, see https://wiki.ubuntu.com/StableReleaseUpdates

Can you help with this problem?
