cups-daemon 升级失败

Question

当我尝试执行时sudo apt-get upgrade，出现以下错误，

Errors were encountered while processing:
 cups-daemon

做sudo dpkg --configure -a给予，

dpkg: dependency problems prevent configuration of cups-daemon:
 cups-daemon depends on libcups2 (= 2.3.1-9ubuntu1.2); however:
  Version of libcups2:amd64 on system is 2.3.1-9ubuntu1.1.

dpkg: error processing package cups-daemon (--configure):
 dependency problems - leaving unconfigured

我怎么解决这个问题？
