I just re-imaged my Raspberry Pi 4 with Manjaro and trying to run the dwservice script which has worked fine in the past and its failing. Any guidance would be appreciated.

Qt Version: 5.15.11
Kernel Version: 6.1.58-5-MANJARO-RPI4 (64-bit)

Product Name: Raspberry Pi 4 Model B Rev 1.4

[root@maia ~]# chmod +x dwagent.sh
[root@maia ~]# ./dwagent.sh

If you mean the shell file from here: https://www.dwservice.net/ Then it checks for python3, not python.

What says: python3 --version ?

Quote:

check_py_ver(){
	if [ "$1" ]; then
		if [ -f "$1" ]; then
			PYVER=$($1 --version 2>&1)
			PYV=$(echo $PYVER | sed 's/.* \([0-9]\).\([0-9]*\).*/\1\2/')
			if [ "$PYV" -ge "36" ] || [ "$PYV" -eq "27" ]; then
				echo "$PYVER"				
				return 0
			fi
		fi
	fi
	return 1
}

if [ "$1" = "-pypath" ]; then
	PYPTH=$2
	check_py_ver $PYPTH
	if [ "$?" = "1" ]; then
		echo "Error: Missing or Invalid Python. Required version 3.6+ or 2.7. Try to use -pypath <path>"
		exit 1
	fi
else
	PYPTH=$(which "python3" 2>/dev/null)
	check_py_ver $PYPTH
	if [ "$?" = "1" ]; then
		PYPTH=$(which "python2.7" 2>/dev/null)
		check_py_ver $PYPTH
		if [ "$?" = "1" ]; then
			echo "Error: Missing or Invalid Python. Required version 3.6+ or 2.7. Try to use -pypath <path>"
			exit 1
		fi
	fi
fi

Thanks for that. I should have checked the script. I am still getting some errors and at this point I think dwservice may need to update their script. Let me know if you have any ideas.

Isn’t it obvious that you need root permissions to install it there? I wonder why it does not trigger a prompt like with sudo or pkexec.

I have been running as root. if you try to run it as user this is what you get.

  1. Install
  2. Run

You must have root privileges to install DWAgent.
Please run the script with sudo or as root.**

Well then the developer will know more. If a log was written, then send it to them.

yep, I was looking for a install log. I did notice that if you select the “Run” option it works.
