ubuntu18.04LTS(WSL) 中的 python package 损坏

Question

我是 ubuntu 的新手，感谢阅读本帖。

我试图删除并重新安装pip和python2.7、python3.6、python3.8等...但是我以某种方式损坏了它，不知道如何修复它。
以下是我用来删除 python 的一些命令：

sudo apt-get remove pythonX
sudo apt-get autoremove pythonX
sudo apt-get purge pythonX
sudo apt-get autoremove --purge pythonX

X 是 2.7 3.6 3.8 等等...

现在我收到这条错误消息，说没有安装 python2.7

freddie@Freddie:/usr/bin$ sudo apt-get autoremove --purge python2.7
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package 'python2.7' is not installed, so not removed
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 cloud-init : Depends: netplan.io but it is not going to be installed or
                       ifupdown
 dh-python : Depends: python3-distutils but it is not going to be installed
 landscape-common : Depends: python3-gdbm but it is not going to be installed
 python3-commandnotfound : Depends: python3-gdbm but it is not going to be installed
 python3-cryptography : Depends: python3-cffi-backend-api-min (<= 9729)
                        Depends: python3-cffi-backend-api-max (>= 9729)
 python3-pip : Depends: python3-distutils but it is not going to be installed
               Recommends: python3-dev (>= 3.2) but it is not going to be installed
 python3-setuptools : Depends: python3-distutils but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
E: Could not read response to hello message from hook [ ! -f /usr/bin/snap ] || /usr/bin/snap advise-snap --from-apt 2>/dev/null || true: Success

但我仍然可以像 python2.7 --version 一样执行 python 命令

freddie@Freddie:/usr/bin$ python2.7 --version
Python 2.7.17

作为建议，我尝试sudo apt --fix-broken install它给了我更多错误，如下所示

freddie@Freddie:/usr/bin$ sudo apt --fix-broken install

The following packages were automatically installed and are no longer required:
  apport-symptoms libexpat1-dev libpython3-dev libpython3.6-dev python3.6-dev
Use 'sudo apt autoremove' to remove them.
The following additional packages will be installed:
  libnetplan0 netplan.io python3-cffi-backend python3-distutils python3-gdbm
Suggested packages:
  network-manager | wpasupplicant python3-gdbm-dbg
E: Could not read response to hello message from hook [ ! -f /usr/bin/snap ] || /usr/bin/snap advise-snap --from-apt 2>/dev/null || true: Success
E: Could not read response to hello message from hook [ ! -f /usr/bin/snap ] || /usr/bin/snap advise-snap --from-apt 2>/dev/null || true: Success

有谁知道如何解决这个问题？
感谢您的阅读。

Answer 1

您的 snapd 已损坏。 尝试以下步骤：

1. 将配置文件“/etc/apt/apt.conf.d/20snapd.conf”移动到备份文件中（不要删除文件）：

   sudo mv /etc/apt/apt.conf.d/20snapd.conf /etc/apt/apt.conf.d/20snapd.conf_bkp

2. 现在安装 snapd：

   sudo apt install snapd

3. 现在将“/etc/apt/apt.conf.d/20snapd.conf_bkp”移回其原始名称：

   sudo mv /etc/apt/apt.conf.d/20snapd.conf_bkp /etc/apt/apt.conf.d/20snapd.conf

4. 您的 apt 现在应该已修复，请尝试其他安装，例如 python3：

   sudo apt install python3 python3-pip

Answer 2

下面的命令应该删除所有 python 包并为 ubuntu 重新安装 python3。

sudo apt remove python*
sudo apt install python3 python3-pip
