问题是我无法删除gnome 外壳和gnome-shell 扩展。当我尝试使用 Ubuntu 软件中心删除时出现错误：
无法解析软件包依赖关系
此错误可能是由于缺少或无法安装所需的附加软件包而导致的。此外，还可能是不允许同时安装的软件包之间存在冲突。
细节：
The following packages have unmet dependencies:
gnome-shell-extensions-user-theme:
And when I try to delete with terminal:
araqkh@araqkh-U30Jc:~$ sudo apt-get purge gnome-shell-extensions
[sudo] password for araqkh:

我怎么解决这个问题？
答案1
gnome-shell-extensions-user-theme 从未出现在官方 Ubuntu 存储库中。使用 PPA 软件时要小心。
您是否尝试过删除 gnome-shell-extensions-user-theme。也许可以删除 gnome-shell*。
