как исправить:

Add debian testing repo to your apt sources by creating a file (with .list extension) on /etc/apt/sources.list.d folder containing the line

deb http://ftp.us.debian.org/debian testing main contrib non-free
Instruct debian to use testing sources on certain packages by creating a file on /etc/apt/preferences.d containing the following:

Package: *
Pin: release a=testing
Pin-Priority: 100
You should name the file something like preferences or testingpref,etc. If you have a preferences file, you can add it there. Remove the .unused or any . in the filename.

Update database:

sudo apt-get update
Install g++:

sudo apt-get install -t testing g++
