Проблемы с зависимостями в Debian Stretch

Question

У меня довольно свежая установка Debian GNU/Linux 9 (растяжка). Я установил python3.7.2 и несколько пакетов python. После попытки установить spyder3 с помощью sudo apt-get install python3-spyderЯ получаю сообщения об ошибках всякий раз, когда я пытаюсь установить или удалить пакеты.

Например, работает sudo apt-get install unixodbc дать следующий вывод:

~$ sudo apt-get install unixodbc
Reading package lists... Done
Building dependency tree       
Reading state information... Done
unixodbc is already the newest version (2.3.4-1).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
12 not fully installed or removed.
After this operation, 0 B of additional disk space will be used.

E: Sub-process /usr/bin/dpkg returned an error code (1)

Это в основном тот же вывод, который я получаю при запуске sudo dpkg --configure -a, также.

Я перепробовал все методы, описанные в этом посте и в этой теме, но ни один из них не решает проблему.

Answer 1

Догадаться. Я установил python3.7.2 в качестве исполняемого файла Python по умолчанию, используя

sudo update-alternatives --install /usr/bin/python python /usr/local/bin/python3.7 1

Это источник моих проблем. Чтобы исправить это, я сбросил его на python2.7.

sudo update-alternatives --remove python /usr/local/bin/python3.7
sudo update-alternatives --install /usr/bin/python python /usr/bin/python2.7 1

Тогда я мог бы сделать

sudo dpkg --configure -a
