我尝试运行 apt-get update 时遇到问题，出现如下错误：
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:
libmysqlclient20 : Depends: mysql-common (= 5.7.13-1ubuntu16.04)
E: Unmet dependencies. Try using -f.
之后我按照建议运行 apt-get -f install，但出现以下其他错误：
Reading package lists... Done
Building dependency tree
Reading state information... Done
Correcting dependencies... Done
The following additional packages will be installed:

我是否应该完全删除 mysql 来修复此问题？请提供意见。
答案1
@mbahlol 我可以通过以下命令修复该问题：
sudo cp /etc/mysql/my.cnf /etc/mysql/my.cnf.fallback
当你第一次做的时候
sudo apt upgrade
mysql-common 解释说它找不到以前的 mysql 配置文件，所以我创建了它，现在看来一切正常，希望你的情况也一样
