The cacti dep8 tests run wget to fetch a lot of pages. At the same time, cacti will shortly begin a network scan, and log its results in the log file.
If the dep8 tests finishes quickly, those network scan results won't be seen in the logs and the test succeeds. If the tests take a little longer, though, it will fail because it will find these "unexpected" log entries:
Unexpected output in /var/log/cacti/cacti.log:

The fix is to probably allow for these messages.
This can be seen by just installing cacti and watching cacti.log. After 2min or so, these log entries will appear.
For which version of cacti is this? I thought I fixed this ages ago.
