卸载mysql报错解决方法1

dpkg: error processing mysql-server (--configure): dependency problems - leaving unconfigured start: Job failed to start

invoke-rc.d: initscript mysql, action "start" failed. dpkg: error processing mysql-server-5.5 (--configure):

ubprocess installed post-installation script returned error exit status 1 dpkg: dependency problems prevent configuration of mysql-server: mysql-server depends on mysql-server-5.5; however: Package mysql-server-5.5 is not configured yet. dpkg: error processing mysql-server (--configure): dependency problems - leaving unconfigured

No apport report written because the error message indicates its a followup error from a previous failure.

Errors were encountered while processing:

mysql-server-5.5 mysql-server

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

解决方法:

删除mysql前 先删除一下 /var/lib/mysql 还有 /etc/mysql

udo rm /var/lib/mysql/ -R sudo rm /etc/mysql/ -R

udo apt-get autoremove mysql* --purge sudo apt-get remove apparmor

udo apt-get install mysql-server mysql-commo

UBUNTU 彻底删除 MYSQL 然后重装 MYSQL

删除mysql

udo apt-get autoremove --purge mysql-server-core-5.5

udo apt-get remove mysql-server

udo apt-get autoremove mysql-server

udo apt-get remove mysql-common //这个很重要 上面的其实有一些是多余的。

清理残留数据

udo dpkg -l |grep ^rc|awk '{print $2}' |sudo xargs dpkg -P
