每次我尝试安装一些东西，升级或自动删除这个错误发生!
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python2.7只安装了3，不能安装python2或任何东西，因为这个。我试过sudo rm python-rpi.gpio_0.7.0-0.1~bpo10+4_armh .deb，但文件会一直来。我真的需要一些帮助，因为我在我的pi上有一些工作，不想得到一个新的图像

一些注意事项:我真的真的不想改变SD卡，特别是失去我所拥有的，第二，我试过sudoapt-get install -f和sudo apt update --fix-missing当我遵循本指南时，sudo dpkg --remove --force-remove --reinstreq命令显示此错误dpkg: error: unknown force/refuse option 'remove'
事实证明，我仍然有Python2和Python3二进制文件的剩余部分，而这些二进制文件没有被操作系统正确链接，这意味着Python3被链接到Python2，反之亦然。
要使它工作，我必须:
- 卸载Python2依赖
- 使链接正常工作
- 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
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
仍然有同样的问题，使用:
sudo mv /var/lib/dpkg/info/python-rpi.gpio.* /tmp/
sudo dpkg --remove --force-remove-reinstreq python-rpi.gpio
命令sudo dpkg --remove --force-remove --reinstreq中的错别字无效。正确的选项是--force-remove-reinstreq。参见dpkg --force-help.
