** Description changed:

  I just did a double Ubuntu upgraded 14.04->14.10->15.04, which sent me
  from mysql server 5.5.43 to 5.6.24.
  
  Now if I run "service mysql start" it hangs and the  mysql log shows
  
  150516 09:47:00 mysqld_safe Starting mysqld daemon with databases from
  /var/lib/mysql
  
  /usr/sbin/mysqld: Can't read dir of '/etc/mysql/mysql.conf.d/' (Errcode: 13 - Permission denied)
  Fatal error in defaults handling. Program aborted
  150516 09:47:00 mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended
  
  Yet as far as permission
  
  # ls -ld /etc/mysql/mysql.conf.d
  drwxr-xr-x 2 root root 4096 May 15 03:56 /etc/mysql/mysql.conf.d
  # ls -l /etc/mysql/mysql.conf.d
