mysql server installation error
I am trying to install mysql with this command -sudo apt-get install mysql-server
but this is resulting in this error.
update-rc.d: error: insserv rejected the script header
dpkg: error processing package mysql-server-5.7 (--configure):
subprocess installed post-installation script returned error exit status 1
dpkg: dependency problems prevent configuration of mysql-server:
mysql-server depends on mysql-server-5.7; however:
Package mysql-server-5.7 is not configured yet.
dpkg: error processing package 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:
E: Sub-process /usr/bin/dpkg returned an error code (1)
I have tried almost all solution like autoclean, autoremove, purge, update dist-update, removing source.list and again creating it. almost every thing..
