Bug#1000957: rkhunter: Problem executing scripts DPkg::Post-Invoke

[Famelis George]

Package: rkhunter
Version: 1.4.6-10
Severity: important

Dear Maintainer,

After running apt-get dist-upgrade, I receive the following message:

[ Rootkit Hunter version 1.4.6 ]
File updated: searched for 182 files, found 160, broken links 1
E: Problem executing scripts DPkg::Post-Invoke 'if [ -x /usr/bin/rkhunter ] &&
grep -qiE '^APT_AUTOGEN=.?(true|yes)' /etc/default/rkhunter; then
/usr/share/rkhunter/scripts/rkhupd.sh; fi'
E: Sub-process returned an error code


The statement in error should be
'if test -x /usr/bin/rkhunter && grep -qiE '^APT_AUTOGEN=.?(true|yes)'
/etc/default/rkhunter; then /usr/share/rkhunter/scripts/rkhupd.sh; fi'
