<div dir="ltr">Hello,
<div><br>
</div>
<div>initially i wanted to just upgrade MythTV .28 to .29. After enabling the .29 repo i was getting dependency errors around libmyth. I ended up doing a Ubuntu release upgrade to 16.04 LTS. That was all going well until i ran into upgraded MySQL to 5.7
and got the table_cache=128 error from the mythtv-tweaks.cnf file. I got this error:</div>

<div>I cleared that line from the file and reran the sudo apt-get upgrade and all seamed okay. I was able to upgrade to .29 without issue.</div>
<div><br>
</div>
<div>The problems began when i went to upgrade the database by running mythbackend from command line. For some reason mythbackend was unable to log into the database. I am able to log into MySQL as root and my MythTV user using the password in /etc/mythtv/config.xml.
The database is still there as well.</div>
<div><br>
</div>
<div>I have tried downgrading MythTV to .28 and still get the same errors. I have also removed MySQL and reinstalled. At this point i am lost. Any ideas?</div>

<div>Thanks,</div>

I also have had problems with the upgrading process. I never could get the upgrade from .27 to .28. So I just backed up all recordings and the database and completely started over and restored the recording and database. Had no problems after that.<br>
<br>
I tried to upgrade in place from 16.04 mythtv .28 to v29, but again too many errors. So I again backed up all the recordings to a NAS and backed up the database. I created a new Ubuntu 16.04 system and went straight to v29 of mythtv. Restored the recordings
and database and all is well.<br>
<br>
That's the only process that I've had work for me. If you are interested I documented what I did recently so I'd have it somewhere to reference if I had to do it all again due to failed hardware or something.
