I'm new to Ubuntu, just installed Mythbuntu 12.04.3 (64-bit) from an iso (single fontend/backend combo). Seemed to instal fine, rebooted my machine only to find I was faced with a screen asking for country and language information (fine; UK, English).

However, the next screen says 'MythTV cannot connect to database' and I am presented with a form (one of two), which already contains data (hostname, password...) so change nothing. I click next (to get to screen two of two) again change nothing (both check boxes are left unticked) and click finish. This sends me back to the original country/language screen.

Is there a fault with the install? Have I missed something in the install/instructions? Is there a way of fixing this?

Appreciate your answers.


Edit your /etc/mysql/my.cnf and /etc/mysql/conf.d/mythtv.cnf files so that the bind address is your server address (the local network address) and not the loopback address (

Once you reboot it should connect. If you're unsure what the password is, nano /etc/mythtv/mysql.txt -- the password is in there.


To get mythbackend to connect to mysql on Ubuntu LTS 14.04.5, I had to manually change the setting in /etc/mythtv/config.xml to the MySQl password. In my case, USER=mythtv | PASSWORD=mythtv, as per the GUI setup screen for mythtv, but that did not match the default values given in the XML file.

Here's what things looked like after the edits were made:

    <Command>echo 'WOLsqlServerCommand not set'</Command>

After that, invoking the mythtv back end manually from the command line (shown below) seemed to show that, at least, mythtv could connect successfully to MySQL:

I have had the same problem and the only solution I have found is to install mythbuntu. There seems to be some sort of a secret mythtv sect that requires a magic decoder ring or special handshake or something in order to give up the answer to this oft-asked question. I have a mythbuntu installation running and it does work but I have never been able to get mythtv to work on an existing desktop.

  • Can you try searching for the specific package?

  • How does this help? The question clearly states that the system was installed from a Mythbuntu ISO. Jan 16 '14 at 11:45
