Ubuntu 16.04 中 Python 包的 apt-get 升级错误

Question

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 libpython3.6 : Depends: libpython3.6-stdlib (= 3.6.5-5~16.04.york1) but 3.6.5-5~16.04.york0 is installed
 libpython3.6-dev : Depends: libpython3.6-stdlib (= 3.6.5-5~16.04.york1) but 3.6.5-5~16.04.york0 is installed
 libpython3.6-stdlib : Depends: libpython3.6-minimal (= 3.6.5-5~16.04.york0) but 3.6.5-5~16.04.york1 is installed
 python3.6 : Depends: libpython3.6-stdlib (= 3.6.5-5~16.04.york1) but 3.6.5-5~16.04.york0 is installed
E: Unmet dependencies. Try using -f.

我已经在 Ubuntu 16.04 中使用 PPA JonathanF 进行安装，并且在我今天遇到这个问题之前一直运行良好。

TI 尝试并得到以下错误：

$ sudo apt-get upgrade -f

Answer 1

这个答案对我有用=)

sudo dpkg --install --force all /var/cache/apt/archives/libpython3.6-stdlib_3.6.5-5~16.04.york1_amd64.deb

从： https //stackoverflow.com/a/50408787/1503549

注意：请记住之后执行以下操作：

sudo apt install -f

将“apt”替换为“apt-get”/“aptitude”，或者您使用的任何 apt-derivative。

Answer 2

看来您的软件包部分已过时。更新软件包列表，然后使用可用的升级来升级已安装的软件包应该可以修复损坏的依赖关系：

sudo apt-get update
sudo apt-get upgrade -f

如果没有，您能否编辑您的问题以包含上述命令的完整逐字输出？谢谢。

Answer 3

您可能从多个位置安装了 python 3.6，这导致了问题（例如http://ppa.launchpad.net/jonathonf/python-3.6/ubuntu ）。

如果是这种情况，您需要从 /etc/apt/sources 中注释或删除它，执行 apt 更新，然后再次尝试 apt-get -f install 。
