[РЕШЕНО] Обновления portage непонятный конфликт зависимостей.

Вообщем конфуз разработчиков, обновляем мир -UD @world и после все остальное.

Сделай python3.7 основным (необязательно, но желательно!) и скомпилируй

eselect python set 3
emerge -uN --nodeps portage -q
emerge -uN --nodeps $(qlist -IC setuptools certifi) -q
emerge -uN --nodeps $(qlist -IC portage) -q
emerge -uDNU --changed-deps=y portage --keep-going -j5 -q

Если где-то будут проблемы - скопируй сюда.

Кстати, забыл упомянуть, что надо добавить python_targets_python3_6 к некоторым пакетам:

/etc/portage/package.use/00_openvswitch:

Было так:

[1] python3.7
[2] python3.6
[3] python2.7
[4] python3.8 (fallback)

После eselect python update стало так:

[1] python3.8
[2] python3.7
[3] python3.6
[4] python2.7

А вот пересборка не помогала никак.

eselect pyhton show дает python3.8.
