最近，我尝试使用我的 ubuntu 14.04 解压 7Z 文件。所以我需要安装 p7zip-full。但是当我尝试安装它时，我收到如下错误：```
emma@emma-AMAX:~$ sudo apt-get install p7zip-full
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: The package gitkraken needs to be reinstalled, but I can't find an archive for it.
``` 而且我的ubuntu软件中心也打不开。我不知道如何卸载 Gitkraken。我使用 Gitkraken 将一些文件 git push 到 mu github repo。但我不知道到底发生了什么。
其他命令输出相同的错误：```
