Bug#697249: rkhunter: cupt reports syntax error in /etc/apt/apt.conf.d/90rkhunter: "E: syntax error: line 4, character 1: expected: semicolon ('; ')"

[Axel Beckert]

Package: rkhunter
Version: 1.4.0-1
Severity: minor

Dear Maintainer,

cupt seems to parse /etc/apt/apt.conf.d/ files more strictly than APT
itself and issues the following warning on rkhunter's apt.conf.d file:

E: syntax error: line 2, character 162: expected: semicolon (';')
E: unable to parse the config file '//etc/apt/apt.conf.d/90rkhunter'
W: skipped the configuration file '//etc/apt/apt.conf.d/90rkhunter'

There are actually two semicolons missing in front of and behind the
closing curly bracket:

Current line 2:

  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" }

Syntactically correct line 2:

  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"; };

See the SYNTAX section in apt.conf(5) and
https://wiki.debian.org/Cupt#line-53 for reasoning and details.
