still it is strange that in my settings /network connections

the wired connection folder says:  never connected
but the bridge virbr0 says connected.

What that means I don´t know.

but it works, that´s the most important

thanks very much.

Now it is working. I can connect to the internet.

After installing Gnuinos the second part your interfaces file

# The first card in the system added for devuan method of networking
auto eth0
    allow-hotplug eth0
    iface eth0 inet dhcp

was completely missing.

I added that and now its working.

thanks for your help

But the 1st question is still unsolved.
I can´t connect to the internet.
I have to enter that command:  sudo dhclient eth0
after that I can use the internet.

Try the below in the file /etc/network/interfaces it tells the system to use the eth0 with dhcp to get the network connection.

oot@9600k:~# cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

# The first card in the system added for devuan method of networking

auto eth0
    allow-hotplug eth0
    iface eth0 inet dhcp

2. question is solved.

I changed my desktop manager into gdm3, then it opened the GUI interface for logging in.
I can choose from the different desktops now.
I am happy.

But the 1st question is still unsolved.
I can´t connect to the internet.
I have to enter that command:  sudo dhclient eth0
after that I can use the internet.
It would be fine to solve this problem.

thanks

In the book of Michael Kofler (Linux Kommandoreferenz)
I found network administration commands.

sudo dhclient eth0

after using that
interestingly was able to connect to the internet.
But it works only for one session. After rebooting into the system the other settings take over.

May be my problem is connected with installing a server besides the desktops.
How can I get rid, uninstall the server?
May be that solves the problem of the internet connection.
Could somebody show me his settings for the network?
So that I can adjust them.

thanks

Is there an option within the automatic install option or any other possible installation methods where I can choose the partition?

The text installer lets you configure your partitions before installing.

the
gnuinos-daedalus_2025.10.12_amd64_desktop.iso    2025-10-12 19:11  3.6G 
did not work today. I wanted to install from there.

So I used the
gnuinos-daedalus_2025.10.12_amd64_netinstall.iso 2025-10-12 19:11  417M 
which worked

For your information:

I choose the expert install mode because I wanted to install Gnuinos on the 2nd partition.
I thought the automatic install option would overwrite my Guix installation on the 1st partition.

Is there an option within the automatic install option or any other possible installation methods where I can choose the partition?

But nevertheless the installation with the expert mode seemed to be ok. It could be that I didn´t choose an option which would be necessary.
I didn´t include proprietary drivers, I used only free drivers.

I installed Gnuinos again with the netinstaller iso and it connected to the repository.
Everything worked seemingly ok.

But starting Gnuinos there is only the terminal without GUI and the possibility to choose different desktops.
In the terminal I can  use "startx" and it opens LXQT as the only desktop.

There is no internet connection available.
I don´t know all the settings.

That´s why I would like to choose another desktop which can automatically detect printer and ethernet connections.
I also installed KDE and MATE and Gnome desktop.
How can I choose KDE desktop in the terminal?

thanks

The sysvinit live ISO also comes with the desktop of your choice, as long as it is XFCE:

UPDATE: the package mirror is up, I just ran apt update successfully.
