+We are providing a `re6st-node` package for many distributions.

+
+  https://build.opensuse.org/package/show/home:VIFIBnexedi/Re6stnet
+
+and find your distribution on the build result at the right of the page.

+
+* Ubuntu 16.04::
+
+   echo "deb http://download.opensuse.org/repositories/home:/VIFIBnexedi/xUbuntu_16.04 ./" >/etc/apt/sources.list.d/re6stnet.list
