    16.04 Distribution Upgrade - cannot start MySQL server

    Today Software Updater had a Distribution Upgrade for my 16.04.2 x64. I was told to do a Partial Upgrade (do not remember the exact reason; assumed it was because I am running a PPA version of GIMP). I did see that there seemed to be considerable changes made to mysql client and server. Now, I cannot start mysql server. Here are some lists :

    I am not sure how to proceed. It seems mysql-server was to be replaced by mysql-server-core.

    Here is my dpkg.log for the dist upgrade:

    I wasn't sure where this post should go, so if it needs to be moved, please do so. Thanks for any help. I am at a standstill in my work.

    I Never accept partial upgrades, with out researching first.
    but for me it was as easy as
    Code:
    sudo systemctl enable mysql.service
    and re-run the upgrade process again.
    Hope it is that simple for you also.

    Unfortunately that did not work for me.

    Code:
    sudo systemctl enable mysql.service
    Synchronizing state of mysql.service with SysV init with /lib/systemd/systemd-sysv-install...
    Executing /lib/systemd/systemd-sysv-install enable mysql
    Failed to execute operation: Unit file is masked
    What does "Unit file is masked" mean? Is there any way to back out the partial upgrade?
