gdebi also tries to use debian/control file as debian archive

[Fabian Niepelt]

Hello,

we are using gdebi to install the build dependencies of packages we are building for internal use.
Parsing the debian/control file and installing the listed dependencies works fine. However, gdebi also tries to use the control file as a debian archive resulting in an error and non-zero exit status:

root@fabian-ubuntu-vm:/home/fabian/UbuntuPackages# LANG=C gdebi foobar/debian/control
Reading package lists... Done
Building dependency tree
Reading state information... Done
Requires the installation of the following packages: apache2

Install Build-Dependencies for source package 'foobar' that builds

Do you want to install the software package? [y/N]:y
[Build Dependencies being successfully installed here]
dpkg-deb: error: 'foobar/debian/control' is not a debian format archive
dpkg: error processing archive foobar/debian/control (--install):
 subprocess dpkg-deb --control returned error exit status 2
Errors were encountered while processing:
 foobar/debian/control
root@fabian-ubuntu-vm:/home/fabian/UbuntuPackages# echo $?
1

Greetings,
Fabian
