Error with pip3 updating youtube-dl

[BentWrench]

Hello All,

My post seems to be a duplicate of [BUG] #402
#402

TL;DR: Pi 1.51 has a bug that will stop Pi Karaoke from launching due to the failure of the youtube-dl update. If you then install into the venv (virtual environment for Python) the youtube-dl update works, but launching using the autostart file doesn't seem to work. A work-around is setting Pi Karaoke up as a service, but that makes it difficult to reboot or shutdown the Pi.

I had a lot of issues resolving this problem. I tried setting up the venv and then using autostart to launch Pi Karaoke, but that didn't work for some reason. I setup the script and auto launch file.

#!/bin/sh
source /home/pi/.venv/bin/activate
pikaraoke

and

[Desktop Entry]
Type=Application
Name=Pikaraoke
Exec=/home/pi/launch-pikaraoke-venv.sh

I can launch it from a terminal with the commands:

source /home/pi/.venv/bin/activate and pikaraoke but they won't launch from the launch-pikaraoke-venc.sh script.

I was able to setup Pi Karaoke in venv as a service. Below is the contents of my service file. It will launch Pi Karaoke on the desktop, so if you are connecting your Pi to a TV or monitor, it will load full screen after it boots to the desktop. It will successfully update youtube downloader. I do not use headless mode, if you do, copy the service file from [BUG] #402.

To install this, create a file named pikaraoke.service, copy it to the /etc/systemd/service/ folder, and then enable auto start of the service with sudo systemctl enable pikaraoke.service. The downside to running as a service, the Shutdown and Reboot commands from the web interface don't work anymore.

Start copying at the next line:

[Unit]
Description=pikaraoke
After=graphical.target

[Service]
WorkingDirectory=/home/pi/.venv/

End copying at the line above.

Here is my original post about the youtube downloader error breaking Pi Karaoke:
I am getting an error in Pi Karaoke 1.51 when it launches. I use this Pi 4 only for Pi Karaoke and it is set to auto start. When I installed it, I used the option to not use a venv for Python.

When I try to launch I get this error below. Should I just re-install using the venv option?

Fixed in 1.5.2 https://github.com/vicwomg/pikaraoke/releases/tag/1.5.2

For the issue where pikaraoke doesn't auto start from the desktop file and sh script, I made one small change to the script and now it works.

#!/bin/sh
source /home/pi/.venv/bin/activate
pikaraoke

Change to

#!/bin/sh
. /home/pi/.venv/bin/activate
pikaraoke

Reason: sh doesn't have the source command, bash does, and changing source to . fixes that.
