我尝试安装 tt-rss，但安装到一半时我决定不安装数据库和 Web 服务器，所以我放弃了安装。现在我无法安装任何更新。软件包管理器告诉我要修复问题才能apt-get -f install安装任何东西。
当我运行时我得到：
root@cabin-htpc:/var/cache/debconf# apt-get -f install

dpkg: error processing package tt-rss (--remove):

Errors were encountered while processing:

E: Sub-process /usr/bin/dpkg returned an error code (1)

我试过了
apt-get remove tt-rss
apt-get purge tt-rss
dpkg -r tt-rss
dpkg -P tt-rss
我猜想“重新加载”是卸载程序试图重新加载从未安装的 Web 服务器和 DB 服务器。我只是不知道接下来该怎么做。
答案1
不确定这是否是最好的方法，但我最终选择了：
/var/lib/dpkg/info
并找到 tt-rss 安装/删除前和安装/删除后的文件
tt-rss.postrm tt-rss.prerm
，我将其重命名为：
tt-rss.postrm.backup tt-rss.prerm.backup
对于那些被禁用的人：
dpkg --purge --force-all tt-rss
努力清除并删除 tt-rss。
