尝试使用 Ubuntu 软件中心更新 manager.io 会计程序。更新失败，并显示：
以下软件包具有未满足的依赖关系：
manager-accounting: Depends: libmono-wcf3.0-cil (>= 2.6.3) but it is not going to be installed here
现在，我无法打开管理器。我尝试重新安装：
$ sudo apt-get install libmono-wcf3.0-cil
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package libmono-wcf3.0-cil is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
libmono-wcf3.0a-cil libmono-cil-dev
E: Package 'libmono-wcf3.0-cil' has no installation candidate
因此，我尝试安装替换包：
$ sudo apt-get install libmono-wcf3.0a-cil
Reading package lists... Done

libmono-wcf3.0a-cil is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
$ sudo apt-get install libmono-cil-dev

libmono-cil-dev is already the newest version.

不能解决问题，我重新安装了所有依赖项libmono-wcf3.0-cil（来源)：
libmono-corlib2.0-cil (>= 2.6.3)– Mono 核心库（适用于 CLI 2.0）libmono-security2.0-cil (>= 2.6.7)– Mono 安全库（适用于 CLI 2.0）libmono-system-messaging2.0-cil (>= 2.6.3)– Mono System.Messaging 库（适用于 CLI 2.0）libmono-system-web2.0-cil (>= 2.10.3)– Mono System.Web 库（适用于 CLI 2.0）libmono-system2.0-cil (>= 2.10.3)– Mono 系统库（适用于 CLI 2.0）
全部返回为已安装的最新版本。
有任何想法吗？
