我想把Ubuntu转换成Xubuntu，但是我遇到了这个问题

Question

使用这个命令apt安装xubuntu桌面，我得到以下信息：

Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.

下列资料可有助于解决这一情况：

The following packages have unmet dependencies:
xubuntu-desktop : Depends: gtk2-engines-pixbuf but it is not going to be installed
               Depends: xubuntu-artwork but it is not going to be installed
               Depends: xubuntu-default-settings but it is not going to be installed
               Recommends: bluez-cups but it is not going to be installed
               Recommends: cups

所报告的错误是由于您没有在您的软件源中启用Universe存储库。

幸运的是，我们有一个很好的问答，详细介绍了这一点--我不会在这里重复相同的信息：

• 如何启用“宇宙”存储库？

启用宇宙存储库后，重新运行更新过程：

sudo apt-get update
sudo apt-get install xubuntu-desktop
