升級到Ubuntu 19.10無法安裝mysql-server-8.0

從 19.04 升級完成後出現錯誤，然後當我運行sudo apt-get upgrade 或 sudo apt-get install mysql-server得到：

E: Sub-process /usr/bin/dpkg returned an error code (1)

我暫時啟用了“預發布更新（eoan-提議）”並再次運行，sudo apt-get update結果sudo apt-get upgrade相同。

我一直在尋找，但找不到合適的解決方案。

關於如何解決這個問題有什麼想法嗎？只要目前資料庫完好無損，我不介意回滾到以前的 mysql-server 版本。

TIA

MySQL 伺服器無法啟動以完成其安裝：

Error while setting value 'IGNORE_SPACE,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION' to 'sql_mode'

在新的 MySQL 版本中，這些 sql 模式中的一種或多種不再可用。就你而言，是的NO_AUTO_CREATE_USER。

請參閱此處的有效模式清單：https://dev.mysql.com/doc/refman/8.0/en/server-options.html#option_mysqld_sql-mode

編輯/etc/mysql/my.cnf並從選項清單中刪除無效模式sql-mode=...

有同樣的問題。這是我修復它的方法。首先備份您的文件

var/lib/mysql

然後清除並重新安裝MySQL

sudo apt purge mysql* mariadb*
sudo apt install mysql-server
