apt-get /usr/bin/datetime.so неправильный класс ELF

Я пытаюсь добавить репо в apt-get бит, который не терпит жалобы на заголовки ELF

sudo add-apt-repository -y ppa:chris-lea/node.js

Я уже пытался переустановить библиотеку datetime с помощью sudo apt-get install --reinstall --purge libpython3.4-stdlib libpython2.7-stdlib

Любая идея о том, как исправить эту проблему? Я бегу: 3.13.0-48-generic #80-Ubuntu SMP Thu Mar 12 11:16:15 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
