MythTV image

[rajil]

Hello,

I would like to build a custom image for MythtvLight for Raspbian Stretch following instructions here and here.

Is this the correct way to setup the repository?

# cat repos/MythTV/multistrap.list.in 
[MythTV]
packages=mythtv-light
source=http://dl.bintray.com/bennettpeter/deb
components=main
suite=__SUITE__
omitdebsrc=true

How can i pull in the gpg package key?

I wouldn't put the packages in there, that means they are required for bootstrapping which isn't the case. Make a plugin for the packages.

since it's a file gpg you'll need to add that to the plugin.

see https://github.com/TheSin-/rpi-img-builder/tree/master/plugins/Foundation/apt-key for an example of hose this is done.

Ok, i created the plugin as follows:

$ cat plugins/mythtvlight/apt-key/preinst 
#!/usr/bin/env bash
set -e
wget https://bintray.com/user/downloadSubjectPublicKey\?username=bintray -O rootfs/apt-keys/bintray-keyring.asc

$ cat plugins/mythtvlight/packages 
mythtv-light

Where do i specify the repo source (deb http://dl.bintray.com/bennettpeter/deb/ stretch myth29)?

[rajil]

I specified the repo details as follows:

$cat plugins/mythtvlight/apt-key/preinst 
#!/usr/bin/env bash
set -e

wget https://bintray.com/user/downloadSubjectPublicKey\?username=bintray -O rootfs/apt-keys/bintray-keyring.asc
echo "deb http://dl.bintray.com/bennettpeter/deb/ stretch myth29" >> rootfs/etc/apt/sources.list

But my build bombed,

Building dependency tree... Done
E: Unable to locate package mythtv-light
rootfs.mak:108: recipe for target '/home/rs4/rpi/rpi-img-builder/rootfs' failed

no you need to keep the repo how you had it just remove the packages= line. So not write to sources.list directly so remove the echo line form the inst script.

in your repo .in file change components=main to components=myth29

then in your make line remember that REPOS should be "Raspbian MythTV"

Thanks, the image is building now.

I need to do a few more steps:

I need to copy file called mysql.txt at /home/pi/.mythtv. If i create a file in the plugins directory would that do the trick?

$ ls mythtvlight/files/home/pi/.mythtv/mysql.txt 
mythtvlight/files/home/pi/.mythtv/mysql.txt

In /boot/config.txt, i need "gpu_mem=256 ". How can this be specified?

[TheSin-]

yes it would

just include you're own version of config.txt in the files as well, copy the one from the base and modify it how you like.

so make files/home/pi/.mthtv/mysql.txt and files/boot/config.txt in your plugin

[rajil]

The files/home/pi/.mthtv/mysql.txt was created on the pi but its permission was set to root:root. The uid:gid should be set to 1000:1000, do i need to create a postint like so?

$plugins/mythtvlight/postinst
#!/bin/sh
chown -R pi:pi /home/pi

[TheSin-]

yes sadly it would be root, in the postinst you can change it though do a chown -r pi: /home/pi or something

Kodi refuses to install for me with an error:

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 kodi : Depends: kodi-bin (>= 2:17.3-1~jessie) but it is not going to be installed
        Depends: kodi-bin (< 2:17.3-1~jessie.1~) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
rootfs.mak:108: recipe for target 'rpi/rpi-img-builder/rootfs' failed

I was building using make REPO="Raspbian MythTV". Any idea why is that?

By the way do i need Foundation in the REPO as well?

[rajil]

I tried to use another kodi repo with files here. Unfortunately, I am not getting the repo definition right:

My repo definition is

# cat repos/Kodi/multistrap.list.in 
[Kodi]
source=http://pipplware.pplware.pt/pipplware
components=main
suite=__SUITE__
omitdebsrc=true

It fails as follows:

I don't know what Kodi uses, but make sure you use the right suite and components for each repo

[rajil]

The Foundation repo file is set to suite=jessie while Raspbian default is stretch. It seems that a bug. Shouldnt both be the same.
