Updated to the latest software/firmware. Not sure why I’m getting the issues I’m getting as it seems the networking isn’t detecting?working?. One of the Netplan files 90-NM seems to be just displaying ^@ repeatedly while the rest look ok (pasting cx7 one below)

Running discover-sparks I get

Found: 169.254.40.39 (gx10-9ee7.local)

Found: 169.254.10.246 (gx10-a532.local)



Setting up shared SSH access across all nodes...

You may be prompted for your password on each node.

  ✓ Successfully configured 169.254.40.39 with shared key



Shared SSH setup complete!

All nodes can now SSH to each other using the shared key (id_ed25519_shared).

Getting this on sparkrun. For some reason it’s giving an error and outputting my password.

Removed all the 90-NM*.yaml . What causes the machine to generate so many of them for hotspot in the first place?
