下面的包有未满足的依赖项python 3.7

Question

在尝试sudo apt-get upgrade时随机获得了这个错误，并且已经尝试运行apt-get -f安装，但没有成功，我该怎么办？

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 libpython3.7-stdlib : Depends: libpython3.7-minimal (= 3.7.3-1+xenial1) but 3.7.3-2~16.04.york0 is installed
 python3.7 : Depends: libpython3.7-stdlib (= 3.7.3-2~16.04.york0) but 3.7.3-1+xenial1 is installed
E: Unmet dependencies. Try using -f.

Answer 1

考虑删除有问题的PPA，然后用以下方法重新安装普通包：

sudo apt-get install ppa-purge
sudo ppa-purge ppa:jonathonf/python-3.7
sudo ppa-purge ppa:deadsnakes/ppa
sudo apt-get install --reinstall libpython3.5-minimal python3-minimal python3.5-minimal
sudo apt-get install --reinstall libpython3-stdlib libpython3.5-stdlib

Answer 2

好的，您似乎使用了另一个带有更高版本包的PPA，然后将它从您的sources.list中删除。这是不可能使易于降低整个软件包的版本。因此，您需要回过头来使用PPA：

sudo add-apt-repository ppa:jonathonf/python-3.7
sudo apt-get update
sudo apt-get upgrade
