Please take a look at https://wiki.debian.org/Teams/MySQL/FAQ for tips on fixing common upgrade issues.

I look at the file permission for this directory and they are 
drwxr-xr-x 2 root root 4096 Feb  3 02:20 mysql.conf.d

How to repeat:
I upgraded mysql-server to 5.7 with apt-get upgrade.

Error out with the about error message.

Uninstalled mysql-server from computer.

apt-get install mysql-server.

Got the same error message.

Hi!

This might be AppArmor related, does command 

 dmesg 

list  any issue?
