我昨晚通过 dpkgsougoupinyin从文件安装了一个软件包sougoupinyin.deb。我记得有一些缺失的依赖项我不知道如何处理。
重新启动计算机后，我尝试通过 apt 安装一些其他软件包。但是，我遇到了这个错误：
littlewhole@pop-os:~$ sudo apt-get install fcitx fcitx-mozc kde-config-fcitx

Processing was halted because there were too many errors.

然后我尝试通过 dpkg 重新安装软件包，并得到几乎相同的错误：

然后我尝试通过 dpkg 卸载该软件包，却收到以下错误：
littlewhole@pop-os:~$ sudo dpkg -r sougoupinyin
dpkg: warning: ignoring request to remove sougoupinyin which isn't installed
此时我决定去askubuntu看看是否有其他人遇到类似的问题并解决了。我找到了一个答案，表明运行此命令可以修复它：
sudo rm -rf /var/lib/dpkg/info/sougoupinyin.*
sudo rm -rf /usr/share/sougoupinyin
sudo rm -rf /etc/default/sougoupinyin
sudo rm -rf /etc/init.d/sougoupinyin
sudo apt purge sougoupinyin
我决定运行这个。 rm 操作成功完成，但apt purge再次遇到错误：
littlewhole@pop-os:~$ sudo apt purge sougoupinyin
Reading package lists... Done

E: The package sogoupinyin needs to be reinstalled, but I can't find an archive for it.
在浏览了更多问题和答案后，我决定尝试一下sudo apt-get -f install，但可惜的是，另一个错误：
littlewhole@pop-os:~$ sudo apt-get -f install

Reading state information... Done
E: The package sogoupinyin needs to be reinstalled, but I can't find an archive for it.
最后，我尝试了sudo dpkg --remove --force-remove-reinstreq sougoupinyin。但即使这样也会引发错误：
littlewhole@pop-os:~$ sudo dpkg --remove --force-remove-reinstreq sougoupinyin
dpkg: warning: ignoring request to remove sougoupinyin which isn't installed
此时，我的系统处于“此软件包存在，您必须重新安装它”和“此软件包未安装”之间的中间状态。我尝试通过 dpkg 重新安装相同的 .deb，但仍然出现错误：
littlewhole@pop-os:~$ sudo dpkg -i '/home/littlewhole/sogoupinyin.deb'

现在，apt正被这些错误所阻碍。我无法通过apt.这显然是一个问题。我无法重新安装或删除此软件包，并且它无法正常工作apt。我应该怎么办？
答案1
正如消息中所暗示的，第 8 行存在一个问题/var/lib/dpkg/info/sogoupinyin.postrm，即删除后程序。
如果您有信心，您可以编辑此文件（以 root 身份）并解决问题，或者如果您确定错误行不是无害的，甚至可以对错误行进行注释。
然后apt-get remove sogoupinyin应该可以工作。
