I did not find it in backports. The situation should be rather stable, tracking here, but I cannot find instructions for the installation in Debian. I cannot use Ubuntu's instructions like here, because they do not work. There are general installation instructions in Debian's wikipage Gnome. There are possible some complications of Gnome 3.14 in some applications (etc Matlab 2016a/b here), which is the reason, I need to test and run the newer Gnome. I do
# https://wiki.debian.org/Gnome $ apt-get install aptitude tasksel $ tasksel install gnome-desktop --new-install $ gnome-session --version gnome-session 3.14.0
I contacted #debian-gnome in Irc, and they say you cannot install Gnome 3.20 in Debian 8.5 stable. You can do it however in Debian 8.5 testing.
- you cannot switch back-and-forth between stable and testing Debian. It seems you have to make a new installation separately for Debian testing.
- Fixed at least when Debian 9 is released with GNOME 3.22 i.e. next year (Feb. 2017).
OS: Debian 8.5 64 bit
Linux kernel: 4.6 (backports)
