Ubuntu 20.04 默认自带 python 3.8 版本。我通过添加 deadsnakes ppa 安装了 python 3.10。运行“sudo apt remove python3.10”时出现以下错误。
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
python3.10-minimal : Depends: libpython3.10-minimal (= 3.10.4-1+focal2) but 3.10.4-1+focal1 is to be installed
Recommends: python3.10 but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
我该如何修复这个问题？我按照建议运行了“sudo apt --fix-broken install”；它给出了以下错误：
Reading package lists... Done

Reading state information... Done
Correcting dependencies... Done
The following additional packages will be installed:
libpython3.10-minimal libpython3.10-stdlib
The following packages will be upgraded:

答案1
今天发生在我身上，请看：这个答案升级 python3.10 时子进程 /usr/bin/dpkg 返回错误代码 (1)
ls -l /var/lib/dpkg/info | grep -i libpython3.10-minimal
sudo mv /var/lib/dpkg/info/libpython3.10-minimal:amd64.* /tmp
sudo apt --fix-broken install
答案2
首先确保您使用python3.8作为默认的python版本。
sudo update-alternatives --set python3 /usr/bin/python3.8
sudo update-alternatives --set python /usr/bin/python3.8
现在，尝试清除 PPA 以删除 python3.10
sudo apt install ppa-purge
sudo ppa-purge ppa:deadsnakes/ppa
