我正在尝试使用以下命令安装 Nitro：
sudo apt-get install nitro
然后我得到了这个：
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:
nitro : Depends: gir1.2-launchpad-integration-3.0 but it is not installable
E: Unable to correct problems, you have held broken packages.
我该如何解决这个问题？

我也遇到了同样的问题，但这对我有用：
http://www.noobslab.com/2012/12/nitro-task-manager-for-ubuntu.html
sudo add-apt-repository ppa:cooperjona/nitrotasks
sudo apt-get update
sudo apt-get install nitrotasks

首先尝试sudo apt-get -f install，然后重试获取 nitro。如果不行，请运行sudo apt-get clean，然后sudo apt-get update。
