[Bug]: Armbian-config Net Problem

[danielmendoncabr]

What happened?

i've compiled my own .img with Armbian Build (i think official img there is no problem)
v25.05 rolling for Orange Pi PC + running Armbian Linux 6.12.23-current-sunxi
Debian rolling (bullseye)
and when trying to edit Network with Armbian-config the follow error occurs

Traceback (most recent call last): File "/usr/sbin/netplan", line 23, in <module> netplan.main() File "/usr/share/netplan/netplan/cli/core.py", line 50, in main self.run_command() File "/usr/share/netplan/netplan/cli/utils.py", line 257, in run_command self.func() File "/usr/share/netplan/netplan/cli/commands/set.py", line 48, in run self.run_command() File "/usr/share/netplan/netplan/cli/utils.py", line 257, in run_command self.func() File "/usr/share/netplan/netplan/cli/commands/set.py", line 58, in command_set self.write_file(set_tree, self.origin_hint + '.yaml', self.root_dir) File "/usr/share/netplan/netplan/cli/commands/set.py", line 108, in write_file new_tree = self.merge(config, set_tree) File "/usr/share/netplan/netplan/cli/commands/set.py", line 85, in merge if key in a: TypeError: argument of type 'NoneType' is not iterable

How to fix:
sudo nano /usr/share/netplan/netplan/cli/commands/set.py

add
import shutil

and search for
os.replace(tmpp, absp)

and change for
shutil.move(tmpp, absp)

if still doesn't work edit
sudo nano /etc/netplan/armbian.yaml

erase everything and paste
because i cannot format here every # means 1 space click, ok? '-'

network:
##version: 2
##renderer: networkd
##ethernets:
####eth0:
######dhcp4: true

(if still doesn't work, erase everything in /etc/netplan/ [must be two *.yaml files] and create a new armbian.yaml with the code above)

moved to configng since not a framework issue.

Debian rolling (bullseye)

I think this also not an armbian-config issues but bug / too old version of NetPlan that comes with bullseye. We just declared end of support for those armbian/build@3af4354

Also try manual way: https://docs.armbian.com/User-Guide_Networking/

There are too much of problems with current stable OS versions (Bookworm / Noble). First install that, try again and report if that solves the issue.

I previously added a JSON entry where nmtui could be integrated with configng in the same way a module would be. Would it be worth adding this to the menu for basic use?

Also some reusable ui module may be useful for Netplan cli wrappers #530

Would it be worth adding this to the menu for basic use?

It won't fix this problem here. Older versions of Debian has too old version of NetPlan, which is likely causing those problems and here we can't do much except recommending upgrade to / using current stable OS. Supporting current user-space is already on the edge of possible, while older variants is simply out of sane range.

I tried to re-create this on Bananapi PRO, A20, which is using same kernel. Logs: https://paste.armbian.com/iketexubuk

• setting fixed IP on LAN
• setting DHCP on wireless
• removing fall back configuration
