[Piuparts-devel] Bug#1084234: piuparts: Cannot create /dev/null

[Joachim Zobel]

Package: piuparts
Version: 1.4.4
Severity: normal

Dear Maintainer,

I am  trying to run

sudo piuparts --fake-essential-packages ca-certificates --testdebs-repo
'https://dl.cloudsmith.io/public/volkszaehler/volkszaehler-org-
project/deb/debian' -d bullseye
/var/cache/pbuilder/result/vzlogger_0.8.8_amd64.deb

This fails with

  Setting up ca-certificates (20210119) ...
  /var/lib/dpkg/info/ca-certificates.postinst: 44: cannot create /dev/null:
Permission denied
  sed: can't read /dev/null: Permission denied

The postinstall script tries to write errors to /dev/null on the line 44.

This might be #1064842, but I'm unsure if essential packages are even allowed
to write /dev/null. What I actually need is that the certificate of the
testbeds-repo is accepted. So if --fake-essential-packages ca-certificates is
the wrong way please consider this a wishlist bug to provide a better way.
