The rkhunter (1.4.2) update issue

I found that the rkhunter v1.4.2 (Debian distro, I don't know about other flavors or versions) had a strange problem. Installed for the first time, I can not update it: 

host:/root# rkhunter --update
Invalid WEB_CMD configuration option: Relative pathname: "/bin/false"

Fixing this in config file (/etc/rkhunter.conf) by removeing /bin/false between quotes I had another error:

ns3:/etc# rkhunter --update
[ Rootkit Hunter version 1.4.2 ]

Checking rkhunter data files...
Checking file mirrors.dat                            [ Skipped ]
Checking file programs_bad.dat                       [ Update failed ]
Checking file backdoorports.dat                      [ Update failed ]
Checking file suspscan.dat                           [ Update failed ]
Checking file i18n versions                          [ Update failed ]

So, digging a little bit I found the following solution. All you need is to replace the followings in the /etc/rkhunter.conf file:

From UPDATE_MIRRORS=0     to UPDATE_MIRRORS=1
From MIRRORS_MODE=1       to MIRRORS_MODE=0
From WEB_CMD="/bin/false" to WEB_CMD=""

The funny thing is that in the rkhunter.conf comments, the recommended values are good. :)
