在安装时sudo apt-get install ubuntu-sdk,我遇到了这个问题，以下软件包具有未满足的依赖关系：
ubuntu-sdk : Depends: qtcreator-plugin-ubuntu-cordova but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
答案1
ubuntu-sdk取决于qtcreator-plugin-ubuntu-cordova。后者需要cordova-ubuntu-2.8，，，。cordova-ubuntu-2.8-devqtcreator-plugin-ubuntuqtcreator-plugin-ubuntu-cordova-common
qtcreator-plugin-ubuntu-cordova由于无法安装，可能会引发此未满足的依赖性问题。
因此运行：
sudo apt-get install ubuntu-sdk qtcreator-plugin-ubuntu-cordova cordova-ubuntu-2.8 cordova-ubuntu-2.8-dev qtcreator-plugin-ubuntu qtcreator-plugin-ubuntu-cordova-common
