最近在安裝MySQL時(shí)，遇到了第三步安裝失敗的問題，以下是我的經(jīng)驗(yàn)分享：

第一步：重啟電腦

sudo reboot

第二步：檢查MySQL依賴項(xiàng)并升級(jí)

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install libaio1 libmecab2

第三步：安裝MySQL

sudo dpkg -i mysql*.deb

然而，安裝過程中出現(xiàn)了如下錯(cuò)誤：

mysql@localhost:~$ sudo dpkg -i mysql-server_8.0.15-1ubuntu18.04_amd64.deb
[sudo] password for mysql:
(Reading database ... 36138 files and directories currently installed.)
Preparing to unpack mysql-server_8.0.15-1ubuntu18.04_amd64.deb ...

Setting up mysql-common (8.0.15-1ubuntu18.04) ...
update-alternatives: warning: forcing reinstallation of alternative /etc/mysql/my.cnf because link group my.cnf is broken
dpkg: error processing package mysql-common (--install):

dpkg: dependency problems prevent configuration of mysql-server:
 mysql-server depends on mysql-common (= 8.0.15-1ubuntu18.04); however:
Package mysql-common is not configured yet.
dpkg: error processing package mysql-server (--install):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 mysql-common
 mysql-server

通過日志可以看到，原因是更新MySQL common時(shí)出錯(cuò)，嘗試卸載該軟件并重新安裝：

sudo apt-get remove mysql-common
sudo dpkg -i mysql*.deb

成功解決該問題！

希望這篇文章對(duì)你有幫助！
