I’d say go back through the install docs again, you must have missed something but it’s not obvious as that is a really odd message to get back.

ok i redid and works when my vm is NOT behind a proxy

if its behind a proxy the install instructions dont work, im using the alternative instructions below

vi /etc/apt/apt.conf

Acquire::http::Proxy "http://ip:port";
Acquire::https::Proxy " http://ip:port";

vi /etc/wgetrc

https_proxy = http://ip:port/
http_proxy = http://ip:port/
ftp_proxy = http://ip:port/
use_proxy = on

apt update

git config --global http.proxy http://<proxy-server>:<port>/

wget https://getcomposer.org/composer-stable.phar
mv composer-stable.phar /usr/bin/composer
chmod +x /usr/bin/composer

curl -x http://ip:port -o /usr/bin/distro https://raw.githubusercontent.com/librenms/librenms-agent/master/snmp/distro

i dont mind this NOT working BEHIND a proxy but what about if i want to update librenms server?

Our docs don’t cover you installing on a box that doesn’t have direct access but I’d expect that as that’s how you run it you would be expected to understand how the commands we provide would need to be updated to get things done, it’s hard for us to offer specific help for every users individual use case.

[robina80]

you mean your docs dont cover non direct access to the internet installs?

[laf]

No they don’t I’m afraid.
