Package: mysql-server-5.7 Version: 5.7.16-2 If one has mysql disabled. (Why have it running 24 a day?!?!) Before upgrade, to avoid grievous half install problems, one must 1. Notice an upgrade is coming (see it in aptitude messages, and then ^C out of aptitude) 2. systemctl start mysql 3. systemctl enable mysql #start is not enough!! 4. aptitude install mysql-server 5. systemctl stop mysql 6. systemctl disable mysql What a hassle. P.S., even if one does this, one will still get an W: message, well at least if one does steps 4, 2, 3, 4 in that sequence.
# aptitude install The following partially installed packages will be configured: mysql-server mysql-server-5.7 Setting up mysql-server-5.7 (5.7.16-2) ... Checking if update is needed. This installation of MySQL is already upgraded to 5.7.16, use --force if you still need to run mysql_upgrade Setting up mysql-server (5.7.16-2) ... W: APT had planned for dpkg to do more than it reported back (3 vs 7). Affected packages: mysql-server-5.7:i386
