need help with armbian/noble network setup,NOT solved

[gene1934]

I have booted it, generated root and user pw's, generated en-utf8 env,  Powered off, copied my /etc/hosts file to it which has hostname and ipv4 address for this., edited /etc/hostname with nano to change it and chattr +i that hostname file so I don't have to redo it every boot. replaced card in bpi-m5. booted up to the new hostname, my pw worked but an ip a is still w/o an ipv4 address which it should get from the hosts file but didn't. . sudo network-manager is not found. Whats next, or what should /etc/network/interfaces look like?

[gene1934]

ip a says interface is end0.

keyboard spastic, finally got rid of repeats so it looks like the man page, restart does not change error message. finally got rid of error message, but no change in ip a , no ipv4 addess for end0, ip a reports only MAC address.

This is west Virginia, USA. no ipv6 service within at least 100 miles of me.

If this is minimal image - we have changed networking config to NetPlan:

solved: took an hour to get it right. yaml is a picky bitch about format but its working.  apt upgrading now.Thank you Igor.

new problem, logged in as gene@amanda, no passwd works for su or sudo. Any fix or do I start all over?  Plus the netplan stuff cannot be found to save it. thanks

Check your /etc/sudoers file to change sudo behavior.

I looked at the man page, last time I played with it was 2 decades ago. Its grown 2500 lines since and at my present age approaching 90, is gibberish.  So I saved the netplan stuff and rewrote the card to start fresh.  thanks Werner
