[Pkg-utopia-maintainers] Bug#928609: network-manager: Invalid system-connections configuration during preseeding

[Yannick Schinko]

Package: network-manager
Version: 1.14.6-2
Severity: normal
Tags: d-i

I'm currently trying to install network-manager during a preseeded installation on a SBC (sing board computer) (It's an APU.2D4) with multiple network interfaces.
I added the package to the `d-i pkgsel/include string` option. It installs just fine and network access during the installation works fine.
However after the installation finishes and the system boots, there is single file under `/etc/NetworkManager/system-connections` called `Wired Connection 1`. This file won't get created when I install the package on a live system.
The huge issue with the file is that all 3 network interfaces are now considered "Wired Connection 1" and cannot be controlled seperately. Running the commands `nmcli con delete $(nmcli -g uuid con); systemctl restart NetworkManager.service` fixes the issue permanetly. (Meaning all 3 interfaces now are named `Wired Connection 1-3` and can be conttrolled independetly. Or the package behaves as it would if it was installed on a live system) (Alternatively the file can be removed while network-manager is off)

The only way I was able to fix this issue was by disabling the NetworkManager service during the late_command script, adding a first boot script and first removing the file then restarting and reenabling the service.
