Comment 7 for bug 977178

I am installing from the terminal with

sudo apt-get install flashplugin-installer

it asks for my password, installs the package, and almost immediately the a window pops up titled "Information available" that states

Failure to download extra data files

The following packages requested additional data downloads after package installation, but the data could not be downloaded or could not be processed.

flashplugin-installer

The download will be attempted again later, or you can try the download again now. Running this command requires an active Internet connection.

When I click on the button "Run this action now" I am asked to enter my password, then a terminal window pops up for an instant and then disappears. It looks like there's an error message displayed in that terminal window but it disappears too quickly for me to read it. That's it, the file with the plugin is not downloaded.

One thing I now noticed is that when I get a root shell with 'sudo bash', wget does not work with my proxy, while it works fine from my user account. Maybe that is actually the problem?
