First of all, let me say this is not my script. I need to install an older .deb package. It evidently uses Python 2, but that is deprecated on the system. I have fixed a number of obvious issues, such as adding parentheses to print statements, but this one has me puzzled. I am no expert at Python.
This is the script up to the point where it fails. It looks simple to me, but I don't understand why it is failing. This is unpacked from the .deb file.
rtc.py:
#!/usr/bin/python
import os;
def runCommand(command):
print (command);
r = os.popen(command);
info = r.readlines();
for line in info:
print (line);
def updateConfig():
filename = '/boot/config.txt';
key = 'dtoverlay';
value = 'i2c-rtc,pcf8563'
fr = open(filename,'rb');
try:
lines = fr.readlines();
update = 0;
newValue = '';
for line in lines :
if line and line.count(key) > 0:
At this point, Python complains:
Failed to enable unit: Unit file embest-shutdown.service does not exist.

The service file issues may be spurious. I will look into them later if they persist, but I don't understand why line.count(key) is an issue. Why can't key be a str object?
Note I did try to install the 2to3 utility, but pip complains about it being an externally-managed-environment
This is running on a Raspberry Pi under Raspberry Pi OS Bookworm.
