【问题描述】：

每次我尝试安装某些东西时，都会发生升级或自动删除此错误！

我已经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 仅 3 并且因此无法安装 python2 或任何东西。我试过 sudo rm python-rpi.gpio_0.7.0-0.1~bpo10+4_armhf.deb 但文件会继续运行。请问我真的需要一些帮助，因为我在我的 pi 上有一些工作并且不想获得新图像

一些注意事项：我真的不想更换 SD 卡并部分丢失我所拥有的，其次我尝试了 sudo apt-get install -f 和 sudo apt update --fix-missing，当我遵循 guide sudo dpkg --remove --force-remove --reinstreq 命令时显示此错误dpkg: error: unknown force/refuse option 'remove'

【解决方案1】：

事实证明，我仍然有剩余的 Python2 和 Python3 二进制文件，并且操作系统没有正确链接这些二进制文件，这意味着 Python3 已链接到 Python2，反之亦然。
为了让它发挥作用，我必须：

卸载 Python2 依赖项
让链接正常工作
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

【解决方案2】：

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。见dpkg --force-help。
