Ubuntu – How to fix AppArmor `could not open` error when installing php+thesql

apparmorMySQL

I want to install php5-imap php5-ldap php5-curl

sudo apt-get install php5-imap php5-ldap php5-curl

I get this error:

AppArmor parser error for /etc/apparmor.d/usr.sbin.mysqld in /etc/apparmor.d/usr.sbin.mysqld at line 9: Could not open 'abstractions/mysql'

How can this problem be resolved?

You are missing the file abstractions/mysql. This happened to me when I tried to completely remove MySQL before reinstalling it. I fixed this issue by replacing the file with a copy from another server. The contents of my file looks something like this:

   /var/lib/mysql{,d}/mysql{,d}.sock rw,
   /{var/,}run/mysql{,d}/mysql{,d}.sock rw,
   /usr/share/{mysql,mysql-community-server,mariadb}/charsets/ r,
   /usr/share/{mysql,mysql-community-server,mariadb}/charsets/*.xml r,

Try creating the file and adding the above contents with:

sudo nano /etc/apparmor.d/abstractions/mysql
