As I reported at the time, in 2015 and due to a lack of Linux expertise, Linden Lab pulled back from active Linux viewer development in favour of seeking support from the open-source community in order to maintain a Linux version of the viewer (see here for more). More recently, the Lab has been looking to provide a means to build a Linux flavour of the viewer, based on their Alex Ivy 64-bit code base and libraries, but not distribute or build all the various dependencies required for the viewer, instead leaving this to TPVs to do as part of providing their own support for Linux users (see here for more), although this is taking time to happen.
In the meantime, on May 6th, 2018, the Kokua team released the first third-party viewer for Linux based on Lab Lab’s 64-bit Alex Ivy code base, although built using Kokua’s own Linux libraries.
Kokua release 126.96.36.199237 (RLV) and Kokua release 188.8.131.52238 (no RLV) are are supplied in Windows, Mac and Linux flavours. In addition, and as is to be expected, both are built using the latest LL release code base (SL 5.1.3) while the RLV version is at parity with RLV release 184.108.40.206.
The viewer is currently available for download on the Kokua website for those who wish to try it – just scroll down to the RLV 64 bit (active development) or the NORLV 64 bit (active development) sections of the download page for the version you’d prefer to use.
If you are a Linux user and opt to download the viewer, please do take the time to report any issues you find with it via the Kokua Issue Tracker at Sourceforge, as refinement and enhancement of the Linux flavour of the viewer is dependent on the Linux community, perhaps more so than the Mac and Windows flavours (which each have the advantage of larger user bases and more chances of issues being more widely identified and reported).
It should be noted that the Linux flavours of the viewers does come with a warning:
Some areas of the Linux release are still being worked on, however we believe that enough is working and well enough to share this with a wider audience to help us squash any remaining gremlins.

However, the news that there is now an up-to-date 64-bit Linux viewer available for download which is based on the Lab’s current code-base should hopefully come as good news for Linux users.
