Bug#869760: Update of rkhunter fails

[Karsten]

Package: rkhunter
Version: 1.4.2-6+deb9u1
Severity: important

Hello,

i can run rkhunter but any update of it fails.


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


When i look in the config i really find this senseless pathname:


# This allows the user to use a command other than the one automatically
# selected by rkhunter, but still one which it already knows about.
# For example:
#
#     WEB_CMD=curl
WEB_CMD="/bin/false"


When i comment out the above line then the update starts but fails again:


rkhunter --update
[ Rootkit Hunter version 1.4.2 ]
