I have been running Ubuntu 24.04 for about a year on my laptop and connections to several wifi hotspots are saved under the network settings applet. I just tried installing an additional SSD and now the system prompts me for passwords when I try to connect to any of my wifi hotspots which were already save earlier.
Possibly relevant...
I have not yet tried to mount or formatted the new SSD.
I noticed that after just plugging in the new SSD and booting up
/is now pointing to the new SSD.When I unplug the new drive and bootup, the wifi works fine without prompting for the credentials and I can find the credentials under /etc/netplan
Now it is possible that /etc/netplan gets mapped elsewere when adding the new SSD though I think it is unlikely. (Not able to verify it now to avoid wear and tear from opening the laptop... opened thrice already). The YAML files under /etc/netplan are named with GUID/UUIDs is it possible the file name is computed by the system at retrieval time and adding the new SSD changes the computed GUID/UUID?
