尝试更新libpython3.6-stdlib会导致覆盖错误

Question

以下是我尝试更新依赖项的错误日志。我觉得--overwrite标志可以用“dpkg”完成工作，但我不确定是否使用它，因为我在那里看到一些交叉依赖。非常感谢你的帮助。

apt-cache策略libpython3.6-stdlib python3-lib2to3 给出这个

Answer 1

试试这个命令：

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

它解决了同样的问题（希望没有任何破坏）

Answer 2

看起来像this issue除了使用不同的包：python3-lib2to3而不是scala。尝试使用清除问题包

sudo dpkg -P python3-lib2to3

我和python3-tk有同样的问题并且为我修复了它。

Answer 3

在我的情况下，我下载了

sudo apt-get download python3.6=3.6.5-3 python3.6-minimal=3.6.5-3 libpython3.6-stdlib=3.6.5-3 libpython3.6-minimal=3.6.5-3

然后

sudo dpkg -i --force-downgrade \*3.6.5\*

并做了！我收回了它！
