Bug#970783: fwupd: its postinst script uses dpkg-vendor that may be not there

[Patrice DUROUX <duroux.patrice@orange.fr>]

Package: fwupd
Version: 1.4.6-2
Severity: normal

Dear Maintainer,

   * What led up to the situation?

The installation of fwupd on a fresh (minimal) Debian Testing system.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

Some error messages occur during the install.

   * What was the outcome of this action?

Nothing special unless the risk having EFIDIR empty at line 17 in the postinst script on run.

   * What outcome did you expect instead?

The installation without such error messages. ;-)

Thanks,
Patrice

ps: the system is not the one from which this report is done.
