有没有嵌入式ubuntu的朋友
问题遇到的现象和发生背景
首先需要我升级ubuntu的 QT和文件系统
输入了 sudo apt-get upgrade
遇到的现象和发生背景，请写出第一个错误信息
显示如下错误

You might want to run 'apt --fix-broken install' to correct these.

使用 sudo apt-get --fix-broken install 显示需要下载一个ghc

其次出现空间不足的情况 请问这种情况怎么处理

磁盘空间不够，重新分区一下，增加磁盘空间，下载分区工具 gparted
系统应用安装的磁盘空间不足，
应该是分区不合理导致，你重新分区下即可解决你的问题。
如果你不想重新分区，你把根目录下占用空间比较大的文件移动到其他目录或删除，即可。
你的目标是不是用新版本QT开发程序，然后在嵌入式系统里运行？
嵌入式开发方式都是交叉编译的，就是在电脑上编译好，拷贝到嵌入式系统里运行。
直接在嵌入式系统里安装开发环境和编译器不是合理的方式，比如导致存储空间不足。
所以你只要找台电脑安装QT就行，嵌入式系统不要升级
开发程序可以用静态编译（不依赖QT的库），或带上需要的QT的库文件（.so）一起拷贝到嵌入式系统
看着是分区没弄好
