I tried to remove and re-add the add-on due to some other issues. I can add the repository manually, but when I go to run the install I get the following:
The command ‘/bin/bash -o pipefail -c git clone -b V2.0 --depth 1 GitHub - sunfounder/pironman’ returned a non-zero code: 128
I have tried removing the add-on and the repository, rebooting the system and re-adding the add-on with the same result.
Currently our pironman software service has been updated to version 1.0.7, please try downloading and installing it again, and if you encounter any problems, please provide complete screenshots of the errors.
If you encounter problems, please provide a complete screenshot of the error. Explain in detail in which part of the process you have a certain problem, it would be better if you have a step-by-step screenshot, so that we can analyze and solve the problem.
How did you fix this? I have the same error and all their support team is doing is sending me links to the regular installation guides 
My Pironman used to work great, now I get this error as well and can’t reinstall. I have tried updating and installing in terminal too but no avail…

Processing... Done.
Error: The command '/bin/bash -o pipefail -c apt-get install git python3 python3-pip python3-setuptools procps -y' returned a non-zero code: 100
My error was the 128, which the release they provided corrected.
You might try doing apt-get -y update before running the install
hmmm…I don’t have an active docker running on pironman due to the installation error. The apt-get -y command is not possible in ha terminal. I believe I need to be in an active container
Did you install via the HA Add on store?
Please follow our tutorial to install and configure the pironman plugin.
https://docs.sunfounder.com/projects/pironman-v2/en/latest/set_up_homeass.html
The error actually occurs during HA Add-on installation. I have linked to the repository correctly (GitHub - sunfounder/home-assistant-addon) and received back the non-zero code:100 error when clicking “install”. I have been in touch with their support via email but they only send links to the publicly posted documentation(s). Any advanced insight you can provide is much appreciated!!
Our current Addon image has been pre-compiled and uploaded to Docker Hub. Previously, it was compiled locally, which took more time and was more prone to issues. Now that it has been pre-compiled, you can simply download and use it.
Please give it a try. (The current latest version is 1.0.12)
