What Linux Distro to choose for beta release testing?

Hi to all!

I’m already testing issues for beta/alpha releases, running in Windows 10/7.

But I want to cross-test those issues in Linux. (Running it in VirtualBox)
I would like it to be easy - just a click or a command - to get the latest release.

(Of course those distribution only have a stable release in their own software repository!)

Regards,

Mike

openSUSE Leap and Tumbleweed have a LibreOffice:/Factory repository that right now offers 6.1 beta2.

for any modern Linux you can use special build with autoupdate (only for 64 bit OS):

https://dev-builds.libreoffice.org/daily/master/Linux-archive-x86_64@80-updater/2018-07-08_00.51.48/

download it, unzip to /home/your-name and start it.
