Comment 0 for bug 1538438

After installing flashplugin-installer I get a prompt noting:
[START]
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.
[END]

Clicking the button Run this action now causes this crash consistently.

Unfortunately, this has the negative outcome of disallowing folks who use Firefox from being able to update, or install Flash.

There are a fair number of these events logged in errors.ubuntu.com.

WORKAROUND: Use Google Chrome/Chromium with pepper flash.
