ERROR: Command failed; error: 1. Log File: /var/log/apphost/management-20221128152921904.log.
Cause
The error occurs when you have incorrect OS level Proxy settings and running manageAppHost as the root user without using sudo
The NO_PROXY setting is missing at the OS level, which needs to match the /etc/systemd/system/k3s.service.env proxy settings.
Resolving The Problem
The NO_PROXY setting at the OS level and in the /etc/systemd/system/k3s.service.env file must match. You need to contact your internal IT department to make those changes.
Use uppercase variables setting the proxy at the OS level (HTTP_PROXY, HTTPS_PROXY, NO_PROXY) as manageAppHost crashes using lowercase variables
Example of current proxy settings at the OS level
#env |grep -i proxy
HTTP_PROXY=http://proxy.corp.com:8080
HTTPS_PROXY=http://proxy.corp.com:8080
Example of the /etc/systemd/system/k3s.service.env file
HTTP_PROXY=http://proxy.corp.com:8080
HTTPS_PROXY=http://proxy.corp.com:8080
NO_PROXY=localhost,127.0.0.1,0.0.0.0,localaddress,corp.com,10.0.0.0/8
* Run this command to add the NO_PROXY Setting for your current session
#export NO_PROXY=localhost,127.0.0.1,0.0.0.0,localaddress,corp.com,10.0.0.0/8
With the NO_PROXY setting now corrected, running this command displays the same information as seen in the /etc/systemd/system/k3s.service.env file
$env |grep -i proxy
HTTP_PROXY=http://proxy.corp.com:8080
HTTPS_PROXY=http://proxy.corp.com:8080
NO_PROXY=localhost,127.0.0.1,0.0.0.0,localaddress,corp.com,10.0.0.0/8
If logged in as the root user and your proxy settings are missing NO_PROXY, then you need to use sudo with the manageAppHost command to run install and upgrade.
Adding the NO_PROXY setting to match the etc/systemd/system/k3s.service.env file permits you to run the manageAppHost commands.
When logged in as the appadmin user, or another non-root privileged user, you are forced to use sudo with the manageAppHost command so the command succeeds.
$ manageAppHost install
Please run this command with sudo.
