我无法卸载Ironhide，或安装任何其他软件包
我安装了Ironhide（又名BumbleBee）。 它无法让它工作，但现在我无法卸载包，它阻止我安装或删除任何其他东西。 我有什么想法可以解决这个问题？
$ sudo apt-get remove -f ironhide Reading package lists... Done Building dependency tree Reading state information...

Errors were encountered while processing: ironhide E: Sub-process /usr/bin/dpkg returned an error code (1) 我通过执行以下操作修复了此问题：
编辑了文件/var/lib/dpkg/info/ironhide.postrm
注释掉了以下内容：
if [ `cat /etc/group |grep ironhide |wc -l` > 0 ]; then groupdel ironhide fi
然后我能够成功运行：
$ sudo apt-get remove ironhide
只需像这样添加组：
sudo addgroup ironhide
然后再次尝试去除铁皮
sudo apt-get --purge remove ironhide
