有时，当我安装东西时，我会收到如下错误：
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.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
package1 : Depends: package2 (>= 1.8) but 1.7.5-1ubuntu1 is to be installed
E: Unable to correct problems, you have held broken packages.
我该如何解决这个问题？
package-management apt ppa dependencies software-installation
我犯了一个可怕的错误并升级到 18.04，而没有通过执行以下操作在不同的分区中进行备份：
sudo apt update
sudo apt upgrade
sudo apt dist-upgrade
sudo apt-get autoremove
sudo apt install update-manager-core
sudo do-release-upgrade -d
然后我在重启后做了更新和升级命令。现在存在许多sudo apt-get -f install命令无法修复的未满足的依赖项和损坏的包问题。更新 sudo apt install -f 错误日志输出的第一部分是：

The following packages have unmet dependencies:
gnome-calendar : Depends: gsettings-desktop-schemas (>= 3.21.2) but 3.18.1-1ubuntu1 is installed
gnome-session : Depends: gnome-shell (>= 3.25.91-0ubuntu4~) but it is not installed
Depends: gnome-session-bin (>= 3.28.1-0ubuntu2) but 3.18.1.2-1ubuntu1.16.04.2 is installed …我知道有很多问题，wine但我无法找到或解决这些问题的答案。有人可以帮我修复有关 Wine 的安装吗？
以下是尝试修复它时的命令输出：

以前，当我只是尝试更新时会收到此错误。我相信这个问题与VLC PPA有关，它在 Ubuntu 上一直是彻头彻尾的垃圾。rm为了清除*vlc*包，我实际上必须删除受包控制的文件。现在，我删除了那个文件，我可以相对轻松地删除 vlc 包。我想这会让我回到开始，我可以再次尝试安装，但是当我这样做时，我收到了这个错误，
sudo apt-get install vlc
