[Simple-cdd-devel] Bug#632331: .udebs or .packages files which are empty or all commented out cause install to fail

[Enrico Zini]

Package: simple-cdd
Version: 0.3.14
Severity: minor

Hello,

I commented out all udebs from my .udebs file and got a big red screen
saying: "loading simple-cdd-profiles failed for unknown reasons.
Aborting".

Investigating the issue I traced it down to simple-cdd-profiles'
postinst:

  [...]
  set -e
  [...]
        echo "Queuing udebs for profile: $p"
        wanted_packages="$(egrep -v ^# $p.udebs)"
	anna-install $wanted_packages || true
  [...]
        echo "Queuing packages for profile: $p"
        wanted_packages="$(egrep -v ^# $p.packages)"
  [...]

Egrep exits with 1 in case no lines are found, and since it's running
under set -e, this terminates the script.

A possible fix is to switch to sed instead of grep:

	wanted_packages="$(sed -n '/^[^#]/p')"
	test -z "$wanted_packages" || anna-install $wanted_packages || true

Ciao,

Enrico
