我已经全新安装了 Debian GNU / Linux 9（拉伸）。
我已经安装了python3.7.2和一些python-packages。
尝试使用sudo apt-get install python3-spyder安装spyder3后，每次尝试安装或删除软件包时，我总是收到错误消息。
例如，运行sudo apt-get install unixodbc会给出以下输出：
~$ 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.

这基本上与我在运行sudo dpkg --configure -a时获得的输出相同。
我已经尝试了this post和this thread中描述的每种方法，但是都无法解决问题。
答案 0 :(得分：0)
弄清楚了。 我已经使用
将python3.7.2设置为默认的python可执行文件。sudo update-alternatives --install /usr/bin/python python /usr/local/bin/python3.7 1
这是我问题的根源。 要修复它，我将其重置为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
那我就可以做
sudo dpkg --configure -a
