Unable to install PIGPIOD to enable DHT22 and DHT11

[trezhunter]

I am trying to enable the DHT22 and DHT11, but I am getting an error:

[2020-07-06 12:41:03] Dependency installation beginning. Installing: file-exists /opt/mycodo/pigpio_installed

When I subsequently go to add a DHT, I get the following additional error:
Error: Add Input: The DHT22 device you're trying to add has unmet dependencies: file-exists /opt/mycodo/pigpio_installed

I was able to install 1.71-0~rpt1 via the console with APT "sudo apt-get install PIGPIOD", but I am not sure how to make it detect in Mycodo. I deleted .dependency and uninstalled in configuration, and it looks like the APT-based install is still present and running. when I grep pigpiod.

Thanks for the bug report. I'll look into it.

I just released v8.5.7, a bugfix release that fixes this issue. Let me know if you experience the same issue after an upgrade.

[trezhunter]

Thanks for the fast update!

It looks to run the install now, but I am seeing some makefile and service errors and it still asks me to install pigpiod each time I try to add a DHT sensor with the same error "unmet dependencies: file-exists /opt/mycodo/pigpio_installed". and shows pigpiod as not installed per the dependency list.

Okay, I released v8.5.8 with a fix that's been tested this time. You should have an error-free dependency install log like this:
