Straight-forward. How do I block upgrading MySQL Server when upgrading Ubuntu from 15.10 to 16.04.3.
Before starting, I held onto various MySQL-5.6 packages with
apt-mark hold <pack>. Then, I followed the upgrade instructions from the official notes on a clone of the target server. I can recreate the initial conditions.
However, the upgrade procedure attempted to install mysql-5.7. Looking with
dpkg -l | grep mysql I now have
rc mysql-server-5.6 -> Desired:Remove, Status:Conf-files
iU mysql-server -> Desired:Install, Status:Unpacked
iF mysql-server-5.7 -> Desired:Install, Status:halF-conf
mysql-*-core-5.7 packages installed (
Instructions I followed
To upgrade on a server system:
- Install the update-manager-core package if it is not already installed.
- Make sure the /etc/update-manager/release-upgrades is set to normal if you are using 15.10, lts if you are using 14.04 LTS.
- Launch the upgrade tool with the command sudo do-release-upgrade.
- Follow the on-screen instructions.
