Title:
Mythbuntu 16.04 LTS upgrade fails due to mythtv-tweaks.cnf for mysql

Status in Mythbuntu 16.10 series:

Status in mythbuntu-common package in Ubuntu:

Bug description:
Upgrading from Mythbuntu 14.04 LTS / mythtv 0.28 to Mythbuntu 16.04
LTS / mythtv 0.28 and mythbuntu repositories disabled.
In Mythbuntu Control Centre, MySQL
"Enable MySQL performance tweaks" is selected.
Ran in terminal:
sudo update-manager -d
3) What you expected to happen
Not sure if this should be reported against mythbuntu-common or
mythbuntu-control-centre but the expectation is that the mysql version be
tested as part of the mythbuntu 0.28 install and the corrected mysql setting be
included in the file.
4) What happened instead
Near the end of the upgrade, mysql server is started, and the
/etc/mysql/conf.d/mythtv-tweaks.cnf file is invoked which contains the line
table_cache=128
According to
https://bugs.mysql.com/bug.php?id=68315
this is now deprecated, and table_open_cache replaces it.
The failure shows up in
/var/log/mysql/error.log
as
[ERROR] unknown variable 'table_cache=128'
[ERROR] Aborting
and mysql shuts down.
It then continues to start up mysql and shutdown again in a continues loop,
effectively hanging.
The process must be killed and intervention is required to complete the
upgrade.
