debian10安装mysql问题

新买的板子，刷的新固件debian，使用默认安装mysql的方式不成功，麻烦看下什么问题？有装成功的吗？

1. toybrick@debian10:~/hutx$ sudo apt install mysql-server
   
2. Reading package lists... Done
   
3. Building dependency tree
   
4. Reading state information... Done
   
5. mysql-server is already the newest version (5.7.30-0ubuntu0.18.04.1).
   
6. You might want to run 'apt --fix-broken install' to correct these.
   
7. The following packages have unmet dependencies:
   
8. mysql-server : Depends: mysql-server-5.7 but it is not installable
   
9. E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
