I appreciate a mindset of moving the environment forward in a safe and secure way. However, the release of Trixie has caused a problem with the classroom structure of my lessons. The conversion to Netplan from NetworkManager has created a snag in my process.
A significant amount of my lessons deal with using headless installations. My class did use the wpa_supplicant file to add networks to the search structure, because the network SSID and PASSCODE were not usually known beforehand. Editing the information using a text editor (nano) made it possible to make the connection while keeping the device headless. This was until Bullseye switched over to using NetworkManager, and the wpa_supplicant file was no longer in use.
I discovered the nmcli process that permitted creation of .nmconnection files in /etc/NetowrkManager/system-connections. It was possible to create a dummy connection file and go back to edit it when the device was being installed at the remote location by adding the proper SSID and PASSCODE in the XML listing. It seems nobody is happy to leave things alone for any length of time.
With the advent of Netplan and the observed intent to continue on this path, my workflow has hit a brick wall. After searching, I discovered that the .nmconnection files have been moved to a temporary area /run/NetworkManager/system-connections. The files have also had the filenames hashed with the only observable reference being the Network SSID. After running an experiment, and creating a "DUMMYNET" SSID and PASSCODE with nmcli, then going back to edit the new file with known working network information; number 1 it didn't recognize the network, and number 2 when I opened nmcli, the information had reverted to the pre-edited data. Meaning the manual changes didn't take.
This is very frustrating and not conducive for an educator. I read that Netplan was only being used by Ubuntu and the branch of Debian had backed the default use out.
If this is true, can I do the same with my RaspiOS installation. I do like the other improvements that happened with Trixie, so I do want to use it for other development, but this is a big impediment.
Thank you,
Jack
