Hi,
I also encountered the same error:
```
Setting up flashplugin-nonfree (1:3.7) ...
ERROR: wget failed to download
http://people.debian.org/~bartm/flashplugin-nonfree/D5C0FC14/fp.24.0.0.194.sha512.amd64.pgp.asc
More information might be available at:

```
It broke my test environment so I reverted to an older version in the
meantime, but it took some time to locate the issue.
What bothers me the most is that it prints an error message to the
standard output but the installation continues as if it worked instead
of failing. The exit code is 0! Would it be possible to fix the handling
of failures to be more explicit ?
