apt - dpkg python-rpi.gpio 依赖问题

问题描述

每次我尝试安装某些东西时，升级或自动删除都会发生此错误！

我在网上搜索并尝试了一些修复，但它们似乎不起作用，我没有安装 python2.7，只安装了 3 个，因此无法安装 python2 或任何东西。我试过 sudo rm python-rpi.gpio_0.7.0-0.1~bpo10+4_armhf.deb 但文件会继续发送。请我真的需要一些帮助，因为我在我的 pi 上做了一些工作并且不想获得新图像

一些注意事项：我真的真的不想更换 SD 卡，也不想丢失我拥有的东西，其次我尝试了 sudo apt-get install -f 和 sudo apt update --fix-missing，当我跟着这个 {{3} } sudo dpkg --remove --force-remove --reinstreq 命令显示此错误 dpkg: error: unknown force/refuse option 'remove'

解决方法

事实证明，我仍然有 Python2 和 Python3 二进制文件的剩余部分，并且它们没有被操作系统正确链接，这意味着 Python3 已链接到 Python2，反之亦然。
为了让它工作，我必须：

• 卸载 Python2 依赖项
• 使链接正常工作
• 使用 wget 重新安装 Python2
• 验证所有链接是否正常工作（对于 Raspbian 这意味着）：
  • python --version 链接到 Python2
  • python2 --version 链接到 Python2
  • python3 --version 链接到 Python3

,

使用以下命令：

sudo dpkg -i --force-overwrite /var/cache/apt/archives//python-rpi.gpio_0.7.0-0.1~bpo10+4_armhf.deb

还是有同样的问题，使用：

sudo mv /var/lib/dpkg/info/python-rpi.gpio.* /tmp/
sudo dpkg --remove --force-remove-reinstreq python-rpi.gpio

您的命令 sudo dpkg --remove --force-remove --reinstreq 中的拼写错误无效。正确的选项是--force-remove-reinstreq。请参阅dpkg --force-help。
