我在安装过程中是否遗漏了某个步骤？我该怎么做才能修复此错误并安装 mysql？
答案1
看来您的问题出在/etc/environment文件上？您能显示该文件的内容吗？该错误似乎表明您有一个 JAVA_HOME 命令而不是设置。
答案2
我在使用 MySQL 和 MariaDB (ubuntu 18.04) 时也遇到了很多问题。我无法让 MariaDB 工作。我使用了https://stackoverflow.com/questions/50573787/how-to-forcefully-remove-mysql-and-mariadb-from-ubuntu-16-04-without-apt-get
$ dpkg --list|grep -i mysql
和
$ dpkg --list|grep -i mariadb
$ dpkg-remove --force-remove-reinstreq
然后按照说明安装 MySQLhttps://dev.mysql.com/doc/mysql-apt-repo-quick-guide/en/
即使重启后也能正常运行。
