我在 16.04 上安装 mySQL 服务器时遇到问题。
我试过：
sudo apt-get install mysql-server
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies.
mysql-server : Depends: mysql-server-5.7 but it is not going to be installed
openjdk-9-source : Depends: openjdk-9-jdk (>= 9~b114-0ubuntu1)
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
然后我看了本指南：
https://www.cyberciti.biz/faq/howto-install-mysql-on-ubuntu-linux-16-04/
第一步，它要求您输入：
$ sudo apt update
$ sudo apt upgrade
第一个命令有效，而第二个命令没有出现与上次类似的错误：
sudo apt upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run ‘apt-get -f install’ to correct these.
The following packages have unmet dependencies.
openjdk-9-source : Depends: openjdk-9-jdk (>= 9~b114-0ubuntu1)
E: Unmet dependencies. Try using -f.
jdk-9 似乎存在问题，但我不知道如何修复。
谢谢

Use 'sudo apt autoremove' to remove them.
The following additional packages will be installed:
