我正在尝试更新 Ubuntu 并更正一些系统设置，但是我面临一个困扰了我一个多星期的问题。
当我输入时sudo apt-get install，我得到：
The following packages have unmet dependencies.
python3.9 : Depends: libpython3.9-stdlib (= 3.9.5-3~20.04.1) but 3.9.5-1+bionic1 is installed
python3.9-minimal : Depends: libpython3.9-minimal (= 3.9.5-3~20.04.1) but 3.9.5-1+bionic1 is installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
所以我运行sudo apt --fix-broken install并得到：

The following additional packages will be installed:

我尝试了一些方法，并在一些论坛中搜索了错误，但找不到解决方案。这真的让我很困惑。

答案1
这对我有用。我找到了出错的软件包并使用以下命令安装它们dpkg：
sudo dpkg -i --force-all /var/cache/apt/archives/libpython3.9-stdlib_3.9.12-1+bionic2_amd64.deb
sudo dpkg -i --force-all /var/cache/apt/archives/libpython3.9-minimal_3.9.12-1+bionic2_amd64.deb
注意：您可能有这些软件包的不同版本，可以使用以下方法找到ls /var/cache/apt/archives/ | grep libpython3.9-
然后我可以更新：
sudo apt-get update -y && sudo apt-get install --fix-broken
答案2
您添加了不必要的 PPA 存储库。要删除它，请使用以下命令：
# sudo apt-get install ppa-purge
cd ~/Downloads
apt-get download ppa-purge
dpkg -x ppa-purge_0.2.8+bzr63_all.deb ppap
sudo cp ppap/usr/sbin/ppa-purge /usr/local/bin/
sudo ppa-purge ppa:deadsnakes/ppa # first for bionic
sudo ppa-purge ppa:deadsnakes/ppa # second for focal
然后从官方 20.04 LTS 存储库重新安装普通 Python 版本：
sudo apt-get install python3.9=3.9.5-3~20.04.1 libpython3.9-stdlib=3.9.5-3~20.04.1 \
libpython3.9-minimal=3.9.5-3~20.04.1 python3.9-minimal=3.9.5-3~20.04.1 --reinstall
然后使用以下命令安装 Aptitude
sudo apt-get install aptitude
并通过以下方式恢复软件包安装
sudo add-apt-repository main
sudo add-apt-repository universe
sudo add-apt-repository multiverse
sudo add-apt-repository restricted
sudo apt-get update
sudo apt-get install -f
sudo dpkg -i --force-all /var/cache/apt/archives/libpython3.9-stdlib_3.9.5-3~20.04.1_amd64.deb /var/cache/apt/archives/libpython3.9-minimal_3.9.5-3~20.04.1_amd64.deb
sudo dpkg --configure -a
sudo aptitude install python3.9=3.9.5-3~20.04.1 libpython3.9-stdlib=3.9.5-3~20.04.1 \
libpython3.9-minimal=3.9.5-3~20.04.1 python3.9-minimal=3.9.5-3~20.04.1

在尝试安装需要 Deadsnakes PPA 中旧版本 Python 的软件后，我遇到了同样的问题。这非常可怕，因为甚至连 synaptic 都让我相信，没有办法降级 Python3.9 而不影响重要的系统软件包，而且这种影响可能无法恢复。
这个命令对我有用。显然，在清除 deadsnakes PPA 后，将下面的软件包版本（使用sudo synaptic或检查）替换为您所需的 Python 系统版本：apt-cache policy python3.9
sudo ppa-purge ppa:deadsnakes/ppa
sudo apt-get update
sudo apt-get install -yf --allow-downgrades libpython3.9-dev=3.9.7-2build1 python3.9-minimal=3.9.7-2build1 libpython3.9-minimal=3.9.7-2build1 python3.9-dev=3.9.7-2build1
