我关注了教程安装 JAVA 8。
但是我收到以下错误消息：
sudo apt-get install oracle-java8-installer
Reading package lists... Done

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:
oracle-java8-installer : Depends: java-common (>= 0.24) but it is not installable
Recommends: gsfonts-x11 but it is not installable
Recommends: oracle-java8-set-default but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
我究竟做错了什么？

Package java-common 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
E: Package 'java-common' has no installation candidate
答案1
以下软件包具有未满足的依赖关系：
oracle-java8-安装程序：依赖：java-common（>= 0.24）但无法安装
建议：gsfonts-x11但无法安装
建议：oracle-java8-设置默认值但它不会被安装 E：无法纠正问题，您持有损坏的包裹。
上面的粗体文字说明了一切。java-common安装
sudo apt-get install java-common
