我使用的是 Ubuntu 20.04
由于某种原因我需要重新安装 Gnome，但现在清除它后我无法重新安装它。我正进入（状态未满足的依赖关系错误。
确切的错误消息 -

其他详情
目前，我正在通过 xfce Desktop 进行此操作。我不喜欢它。
我没有安装 GDM。
我只想要 ubuntu-gnome-desktop。
这个未满足的依赖关系问题仅存在于与 gnome 相关的软件包中。
如果您没有任何有关 ubuntu-gnome-desktop 的解决方案，那么我也可以仅安装 gnome 桌面，但这不是首选。

对我有用的：
我只是安装了ubuntu-desktop.您可以通过以下方式安装它：
sudo apt install ubuntu-desktop^
^表示任务包
如果您更喜欢 GUI：
sudo apt install tasksel
sudo tasksel
# arrow keys to navigate and space bar to select.
选择ubuntu桌面并按回车键
其他一些可以尝试的事情：
首先，尝试更新存储库：
sudo apt update
如果这不起作用，请尝试使用强制安装：
sudo apt -f install ubuntu-desktop
您还可以尝试使用aptitude：
# install aptitude
sudo apt install aptitude
# install the packages
sudo aptitude install ubuntu-desktop
## aptitude will suggest solutions to fix the error, if you find them ok then accept the solutions.
aptitude与-f参数一起使用。
sudo aptitude -f install ubuntu-desktop
-f与任务包一起使用：
sudo aptitude -f install ubuntu-desktop^
尝试从缓存目录中删除错误.deb文件。apt
sudo rm /var/cache/apt/archives/*.deb
尝试清除冲突包的状态：
# create a backup first:
sudo cp -r /var/lib/dpkg/status /var/lib/dpkg/status.bak
# view the file:
view /var/lib/dpkg/status
# Now, find the information given about the error packages and try removing it.
尝试自己安装依赖项：
sudo apt install <package>
尝试安装正常版本的软件包 iegnome-session
sudo apt -f install gnome-session
