Comment 1 for bug 1468129

Hi Andrey,

if you use proxy for Internet access you need to configure this proxy for yum tool. To do this, you need to edit file /etc/yum.conf and add the following strings to this file (proxy address, port and credentials will depends on your environment):

# The proxy server - proxy server:port number
proxy=http://mycache.mydomain.com:3128
# The account details for yum connections
proxy_username=yum-user
proxy_password=qwerty

More details:

But, of course, we have a bug - if we successfully installed plugin we need to support uninstallation and updates for this plugin and dependencies.

We need to add logic which will check the Internet connectivity and use external mirrors only if we have the Internet access.
Confirmed and assigned to Fuel-Python team.
