运行 apt-get upgrade 时未满足 cups 的依赖关系

当我运行时，sudo apt-get update它显示以下内容：

$ sudo apt-get update
Get:1 http ://security.ubuntu.com/ubuntu xenial-security InRelease [102 kB]
Hit:2 http ://in.archive.ubuntu.com/ubuntu xenial InRelease
Hit:3 http ://in.archive.ubuntu.com/ubuntu xenial-updates InRelease                 
Hit:4 http ://in.archive.ubuntu.com/ubuntu xenial-backports InRelease               
Fetched 102 kB in 2s (51.1 kB/s)                             
Reading package lists... Done

之后当我运行时sudo apt-get upgrade它显示：

$ sudo apt-get upgrade
Reading package lists... Done
Building dependency tree       
Reading state information... Done
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 cups : Depends: cups-daemon (>= 2.1.3-4ubuntu0.2)
 cups-core-drivers : Depends: cups-daemon (>= 2.1.3-4ubuntu0.2)
 cups-daemon : Depends: libcups2 (= 2.1.3-4) but 2.1.3-4ubuntu0.2 is installed
E: Unmet dependencies. Try using -f.

有什么解决办法吗？

答案1

运行dpkg -l | egrep '^ii.*cups'以查看已安装的所有 CUPS 软件包。如果其中一些软件包的版本为2.1.3-4ubuntu0.2，请使用以下命令将其恢复为2.1.3-4版本

sudo apt install package1=2.1.3-4 package2=2.1.3-4 ...
