This is to capture information about my current hardware and setup as it may be useful to other new or inexperienced users.

Hardware

Existing hardware

Logitech Harmony 665
HDHomeRun Quatro
infrared remote receiver
Rosewill R379-M MATX

New hardware

Total $482

I have these selected at https://pcpartpicker.com/list/vf9nqm

Hoping that these will be suitable with the case I already have Rosewill R379-M MATX

My current plan is to install Ubuntu 22.04

Partitioning

apparently UEFI Bios tries to find a partition in a GPT-partitioned boot device. This partition needs to be tagged with "EFI System" and also needs to be formatted with FAT filesystem.
I ran "sudo gparted &"
used Device menu to create partition table to gpt
followed https://askubuntu.com/a/743098

Install Ubuntu

normal installation, download updates while installing, install third-party software & Secure Boot (chose password)
installation type / something else

Install MythTV

i'm installing MythTV via the Mythbuntu Control Panel. I'm following instructions at Mythbuntu_Control_Panel.

sudo add-apt-repository ppa:mythcp/mcp
sudo apt-get update
sudo apt install mythbuntu-control-panel

The first sudo needed my password, but the others were executed soon enough that I didn't need to enter it again.

launched Mythbuntu Control Panel
went to *Repositories* tab
checked box "Activate MythTV Updates repository"
selected version 32
checkbox for "Activate Mythbuntu Control Panel repository" was *already* checked
clicked "Apply" box

A summary of the changes that will be applied is below:
Repositories:
- Reconfigure (as root) the following items:
	MythTV-Updates-Repo
	MythTV-Updates-Activated
	Repo-list

clicked "Apply"
it required my password, then popped-up a progress bar, then returned to the control panel.
exited Mythbuntu Control Panel
opened Software Updater. saw some updates, but nothing related to MythTV ... hmmm ...
needed to restart

I ran Software Updater again, but didn't see MythTV items. So, I ran "Software & Updates" and chose the "Other Software" tab. There, I could see an item named https://ppa.launchpadcontent.net/mythbuntu/32/ubuntu/jammy which looks like the repository for MythTV 32. I ran "sudo apt-get update" again and I could see the aforementioned repository in the output, so it seems like it is reading it.

went to "System Roles"
selected "Primary Backed", "Use XMLTV for guide data" (I have an account with Schedules Direct), "Enable SSH", "Desktop Frontend", "HDHomeRun Config" (I have an HDHomeRun tuner), "HDHomeRun Config GUI" (why not)
Clicked "Apply"

System Roles:
- Install the following items:
	mythtv-backend-master
	mythtv-frontend
	xmltv
	openssh-server
	hdhomerun-config
	hdhomerun-config-gui

Clicked "Apply" and entered password. this took a little longer than the time. something popped up and i accidentally closed it :(

went to "Setup"
selected "User in mythtv:group", clicked "Apply", clicked next "Apply", entered password

Setup:
- Reconfigure (as root) the following items:
	user_in_mythtv_group

rebooted the computer
launched Mythbuntu Control Panel and went to "Setup"
selected "Link to config.xml"

Setup:
- Reconfigure (as user) the following items:
	link_config_file

clicked "Apply" and also the next "Apply"
the option to enable networking was grayed out with the message "Apply this after configuring MythTV Backend if networking is needed"

Restore From System 0

Based on my notes at System 0 Update

$ cp -pr '/home/troy/sysB/home/troy/.mythtv/' mythtv1
$ rm mythtv1/config.xml 
$ mv mythtv1/* .mythtv/.
$ rm -rf .mythtv/HardwareProfile/ .mythtv/cache/ .mythtv/tmp/
$ cp -pr '/home/troy/sysB/home/troy/.lirc' .lirc
$ cp -pr '/home/troy/sysB/home/troy/.lircrc' .

for the purpose of testing my setup without damaging my existing recordings, I will not mount my 2TB storage disk. Instead, I'll just create the /storage directory locally:

$ sudo mkdir /storage
$ sudo chmod a+rwx /storage
$ sudo mkdir /storage/mythtv
$ sudo chmod a+rwx /storage/mythtv/

I also am importing my old mythtv database file following instructions at Database_Backup_and_Restore

$ ls -Ftl --full-time /usr/share/mythtv/mythconverg_restore.pl

Successfully restored backup.

Found DBSchemaVer: 1361.
Setting database character set.

now, let's run the backup setup GUI, again, to see if it looks like it really did it... I checked "Run MythTV Backend Setup as mythtv user" and clicked "MythTV Backend Setup" button. Message: "Warning:MythTV wants to upgrade your database, for the TV schema,from 1361 to 1376. Database Host:localhost Database Name: mythconverg" I clicked "Upgrade"

set the security pin
this server is the master backend
delete files slowly -- maybe this will be helpful?

added capture card for HDHomeRun
- Use HDHomeRun for active EIT scan [x]
noted that Recording Profiles had an entry for the HDHomeRun, so I clicked 'save'
under Connections
- I set the name to "Input 01"
- started a channel scan, saw these messages:
  - Found 2 off-air channels
  - Found 166 old ATSC channels
  - Found 2 new ATSC channels

- default storage group directories: /storage/mythtv
exited setup

$ sudo service mythtv-backend start
$ mkdir -p ~/Maintenance/mythtv/fill
$ sudo -u mythtv mythfilldatabase | tee ~/Maintenance/mythtv/fill/mythfilldatabase_log_20230107.txt

I saw a message

2023-01-07 14:03:36.646108 I  XMLTV config file is: /home/mythtv/.mythtv/tdgood.xmltv
2023-01-07 14:03:36.897392 E  XMLTV grabber returned error code 1
2023-01-07 14:03:37.046022 E  Malformed XML file, missing </tv> element, at line 1, Premature end of document.

and I noticed that file was missing, so I copied it over from my previous setup

$ sudo  cp /media/troy/ec87d246-a931-4336-9a04-d4399ba2c53b/home/mythtv/.mythtv/tdgood.xmltv /home/mythtv/.mythtv
$ sudo chown mythtv:mythtv /home/mythtv/.mythtv/tdgood.xmltv
$ sudo -u mythtv mythfilldatabase | tee ~/Maintenance/mythtv/fill/mythfilldatabase_log_20230107b.txt

that output looked better

Testing Live TV

I started the frontend and chose "watch tv" but I received a message that all tuners were busy. It was already recording a show. I stopped the recording and was able to access live TV. However, i did see a message

Disabling Audio
Audio Player
AOSS: Error opening audio device ():
eno: No such file or directory (2)

so, in the frontend setup, I went to the setup wizard

I chose "ALSA:default". the speaker test only activated the left, center, and right speakers of my 5.1 setup but I left it there for now.

Under video configuration, I left it at "NVDEC Normal" for now

Testing Frontend

I copied a few files from my old storage directory

Storage directory

I used "sudo blkid" to get the info for editing /etc/fstab:

$ cat fstab
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/nvme0n1p3 during installation
UUID=9f234e2e-43f0-445d-b1da-c4cf05f14827 /               ext4    errors=remount-ro 0       1
# /boot/efi was on /dev/nvme0n1p1 during installation

#   added manually by troy 2022-dec-07 from old /etc/fstab
UUID=d70970b0-e22c-47ae-a9e0-5d9c637aa073  /storage       jfs     defaults        0       2

$ sudo mv /storage /teststorage
$ sudo mkdir /storage

I used "sudo mount -a" to verify that it mounted properly and that I had access to the 2TB drive via /storage

backups

$ cd /etc/cron.daily
$ sudo cp -pr /storage/backups/daily-202212/etc/cron.daily/mythconverg-backup /storage/backups/daily-202212/etc/cron.daily/rsync-backup .
$ cd /etc/cron.weekly
$ sudo cp -pr /storage/backups/daily-202212/etc/cron.weekly/rsync-backup /storage/backups/daily-202212/etc/cron.weekly/mythconverg-backup .

in the Mythbuntu Control Panel, I selected "Automatically start MythTV Frontend" I also enabled MythWeb and MythWeather and rebooted.

configured my HDHomeRun quatro per https://www.mythtv.org/wiki/Channel_Scanning#Scanning_with_HDHomeRun_tuners

In Ubuntu's settings, under power, "Power Saving Options", I chose Screen Blank -> Never

Remote Control and LIRC

i have previously configured LIRC with my remote control. Apparently, neither Ubuntu nor MythTV has given my LIRC (also https://www.lirc.org/ https://help.ubuntu.com/community/LIRC). The current version looks like 10.2

$ sudo apt-get install lirc

The installation didn't show any error messages. My IR receiver has a red light to show it is receiving data, but that wasn't responding when I pushed buttons on the remote. I unplugged the IR receiver's USB connection and plugged it back in -- now, I see the red light blinking in response to button pushes! However, the MythTV frontend is not responding to the remote control.

I had already copied files for ~/.lirc and ~/.mythtv/lircrc Some configuration still needs to be done.

$ sudo cp -pr /storage/backups/daily-202212/etc/lirc/lircd.conf.d/tivo_and_atlas4.conf /etc/lirc/lircd.conf.d/.
$ sudo cp -pr /storage/backups/daily-202212/etc/lirc/copy/hardware.conf /etc/lirc/
$ ls -FtlRa /etc/lirc

Other Software

sudo apt install plocate
sudo apt install imagemagick
sudo apt install lvm2

 my old SSD was formatted using LVM, so I needed this, I think
