The following env variables have been found for the current user:
${OSM_PROXY_ENV_VARIABLES}.

This suggests that this machine is behind a proxy and a special configuration is required.
The installer will install Docker CE, LXD and Juju to work behind a proxy using those
env variables.

Take into account that the installer uses apt, curl, wget, docker, lxd, juju and snap.
Depending on the program, the env variables to work behind a proxy might be different
(e.g. http_proxy vs HTTP_PROXY).

For that reason, it is strongly recommended that at least http_proxy, https_proxy, HTTP_PROXY
and HTTPS_PROXY are defined.

Finally, some of the programs (apt, snap) those programs are run as sudoer, requiring that
those env variables are also set for root user. If you are not sure whether those variables
are configured for the root user, you can stop the installation now.
