It was only suggested for a period of about three weeks: We are planning to switch the default Python target of Gentoo systems on 2021-06-01, from Python 3.8 to Python 3.9. If you have not changed the values of PYTHON_TARGETS or PYTHON_SINGLE_TARGET, the change will have immediate effect on your system and the package manager will try to switch automatically on the next upgrade following the change. > > But also when trying "emerge -1vUD @world" (be it with or without the > package.use settings), I get stuck in conflicts (mostly on perl and > setuptools). perl issues would probably resolve once I have EAPI8 > support, i.e. get new portage. > > You can try --backtrack=200 (or a larger value) to fix that; it was a problem for a lot of people. Even though the end result of both approaches is "it doesn't work," I promise you you're better off not messing with the python stuff until the system is fully upgraded. Upgrading a year-old system is hard enough, and the introduction of EAPI=8 just made it worse.
