Ubuntu, я изменил версию Python по умолчанию для моей системы с python2.6 -> python2.7.
после
sh-3.1$: update-alternatives --install /usr/bin/python python /usr/bin/python2.7 2
sh-3.1$: sudo update-alternatives --config python
There are 2 choices for the alternative python (providing /usr/bin/python).
Selection Path Priority Status
------------------------------------------------------------
0 /usr/bin/python2.7 2 auto mode
1 /usr/bin/python2.7 2 manual mode
* 2 /usr/lib/python2.7 1 manual mode
Press enter to keep the current choice[*], or type selection number: 0
update-alternatives: using /usr/bin/python2.7 to provide /usr/bin/python (python) in auto mode.
Думаю, я изменил версию по умолчанию, и команда python показывает нормально.
sh-3.1$: python

Ошибка показывает, что apt-get все еще использует версию python2.6.
Как мне это исправить?
Попробуйте обновить свой apt-get с помощью:
sudo apt-get update
