Backend on raspberry pi 3

[Jeff42]

Hi all I'm looking to setup mythtv as a backend for my ota setup. I have the antenna and an hd home run setup working but am having problems getting mythtv backend to install on my pi 3.

These are the steps I've done so far but get the errors at the bottom when trying to install myth TV light. The wiki doesn't really offer anything else. Why are those things not installable? Do I need a.pi 4?

sudo apt-get install mysql-server
sudo apt-get install mythtv-backend
sudo apt-get install mythtv-database

Add the following line to the file /etc/apt/sources.list:
sudo nano /etc/apt/sources.list
deb http://dl bintray com/bennettpeter/deb/ jessie myth27
deb http://dl bintray com/bennettpeter/deb/ jessie myth28
deb http://dl bintray com/bennettpeter/deb/ jessie myth29
deb http://dl bintray com/bennettpeter/deb/ stretch myth28
deb http://dl bintray com/bennettpeter/deb/ stretch myth29
deb http://dl bintray com/bennettpeter/deb/ stretch myth30
deb http://dl bintray com/bennettpeter/deb/ buster myth30
#Run once
wget -O -
https://bintray com/user/downloadSubjectPublicKey?username=bintray |
sudo apt-key add - sudo apt update

#Install the package
sudo apt-get update
sudo apt-get upgrade
sudo reboot
sudo apt-get install mythtv-light

The following packages have unmet dependencies:
mythtv-light : Depends: libtag1v5 but it is not installable
Depends: libexiv2-14 but it is not installable
Depends: python-future but it is not installable
Depends: python-requests-cache but it is not installable

I think you may have added too many lines to /etc/apt/sources.list, you only need one depending on Raspbian and mythtv version.

I suggest the following.

Use "Raspbian Buster with desktop" downloaded from https://www.raspberrypi.org/downloads/raspbian/

Add the following line to file /etc/apt/sources.list

Code: Select all

deb http://dl.bintray.com/bennettpeter/deb/ buster myth30

You then need to do the run once of, note the - at the end of the line

Code: Select all

wget -O - https://bintray.com/user/downloadSubjectPublicKey?username=bintray | sudo apt-key add -

followed by , this installs mythfrontend and mythbackend but not mysql database etc - see below for a helper script.

Code: Select all

sudo apt update
sudo apt install mythtv-light

The next line is optional and only needed if you want mythplugins (e.g. mythnews, mythbrowser), these are used by mythfrontend, not required for mythbackend operation.

Code: Select all

sudo apt install mythplugins-light

There is a helper script (works for Pi4 or Pi3) which automates installation of all the items (mythtv user, database etc) for a complete mythbackend see viewtopic.php?f=46&t=3232#p15773

If you need to move the root filing system from the microSD card to external USB storage (SSD, Hard disk or even a flash drive) there is another helper script which will do this see viewtopic.php?f=46&t=3232&start=15#p15884

My brother(or sister) thank you. I'm getting an sd card writer to put the iso on it then I'll do all those things.

Much appreciated.
