Bug Description

Binary package hint: flashplugin-installer

I work at a primary school, and my network is behind a filtering proxy / firewall system. All web traffic is blocked except through the filtering proxy.

I've set the correct proxy settings in the "system / network proxy" box, and clicked "apply system-wide". I've also set the correct proxy settings in Synaptic. I even tried re-starting to see if that would make those settings take effect. Despite this, flashplugin-installer attempts to connect directly to the web, and fails.

I'm using 10.04 lucid 64-bit, and synaptic is trying to install flashplugin-installer 10.1.53.64ubuntu0.10.04.3

Steps to reproduce:
1: Set up a network segment with a firewall.
2: Set up a proxy on the boundary of that segment, or outside it.
3: Block all outward traffic on port 80 except that to the proxy.
4: Attempt to install flashplugin-installer.

I'm not sure, but maybe this bug is dependent on this one:

try edit this file and add the 2 lines:

ftp_proxy = http://10.0.0.2:3128/

Andy - it'll be a couple of weeks until I'm next behind a firewall, and I can test that. I've just looked on my system, though, and that file doesn't exist - I'm assuming the installer removes it after it runs. Are you suggesting I replace that file during the installer's execution?

I added the 2 lines to the file /etc/wgetrc :
  http_proxy = http://10.0.0.2:3128/
  ftp_proxy = http://10.0.0.2:3128/

I did a locate for "wgetrc" and found - /var/cache/flashplugin-installer/wgetrc
    So I added those 2 lins in there aswell.

re-running the apt-get upgrade - seemed to then just work.....

Thanks, Andy - I'll use that to get the plugin installed. I don't think that helps solve the bug, though.

no its still an annoying little bug..

The server-wide proxy should cover it (sigh)

I had the environment variable http_proxy set correctly, but sudo removes them. You can use the -E flag to sudo to preserve all environment variables. (Compare 'env', 'sudo env' and 'sudo -E env'.)

sudo -E aptitude install flashplugin-installer

worked fine for me. sudo -i ... would probably work too, if your system's environment is set up correctly.

Hmmm. I was installing this package through synaptic. Is this actually a bug in synaptic, rather than in flashplugin-installer?
