Bug#523412: update-manager: Did nor work with apt-cacher and active system-proxy

[Stephan Peijnik]

Hi,

First of all I'd like to thank you for your bug report. I am currently
trying to check if old bugs have been fixed in the update-manager 0.200
series, so could you please check if you can reproduce the bug with
0.200.0-1 (currently in unstable)?

Thanks,

Stephan
