I don't think the package name will include the version. Please [edit] your question and post the output of `apt-cache show 'g++'`. Alternatively, just try `sudo apt-get install g++`. — terdon, Jun 20 '16 at 18:36
@terdon my experience on 14.04 is that `apt-cache policy g++` will just show the standard repo version i.e. 4.8.x (because it's just a dependency package), whereas `apt-cache policy g++-4.9` should pick up the toolchain repo version. — steeldriver, Jun 20 '16 at 18:48
Perhaps the catalog isn't getting updated at all because of the transport error (`method driver /usr/lib/apt/methods/https could not be found`)? — steeldriver, Jun 20 '16 at 18:49
@steeldriver thanks. Now i fix this error, and apt-get update fix all errors. — L30m4nc3r, Jun 20 '16 at 19:01

The toolchain repository requires https access, so because of the error

E: The method driver /usr/lib/apt/methods/https could not be found.

your package catalogue is not being updated even though you have successfully added the repository.

You can find some suggestions to fix the error at “method driver /usr/lib/apt/methods/https could not be found” update error - if you're lucky (meaning that plain http method is not also broken) it should be as simple as installing - or possibly reinstalling - the relevant package

sudo apt-get install apt-transport-https
