I've installed python3.4 from the deadsnakes repo, and I'd like to make it my default python3 (which is currently python3.2). Is it safe to simply change the python3 link?

sudo ln -s /usr/bin/python3.4m /usr/bin/python3

Are there system components that would die due to an inability to work with python3.4 instead of python3.2?

If you do that

  • python3.4 will not find modules installed in places like /usr/lib/python3.2/. That includes all modules installed by the package manager.
  • modules containing binary libs compiles against Python 2.3 will likely not work without recompiling.

That means that almost all programs from the official repositories needing Python3 will stop working.
