I can confirm the description of mikewse in comment #16.
If I get an update of flashplugin-installer via update-notifier, the update fails because the proxy settings are not used. I then ran:
sudo dpkg --purge flashplugin-installer; sudo apt-get install flashplugin-installer
and the package download works just fine.
My /etc/environment has settings for (example.com inserted in place of real domain):
http_proxy="http://proxy.example.com:3128/" ftp_proxy="ftp://proxy.example.com:3128/" https_proxy="https://proxy.example.com:3128/" socks_proxy="socks://proxy.example.com:3128/"
In addition, the same proxies are configured in /etc/apt/apt.conf:
Acquire::http::proxy "http://proxy.example.com:3128/"; Acquire::ftp::proxy "ftp://proxy.example.com:3128/"; Acquire::https::proxy "https://proxy.example.com:3128/"; Acquire::socks::proxy "socks://proxy.example.com:3128/";
These environment variables are available in both "sudo -s" and "sudo -i".
The proxy was configured via the network settings tool as manual configuration and applied system-wide.
It seems that update-notifier does not provide these proxy settings to package-data-downloader.
