[16:09] <webchat24> Hello all, i installed ubuntu server 20.04 LTS and  imported a SSH keys from Launchpad. i am a little bit lost, there is a lot of tuturial showing how to generate a key but i dont know what can i do now with the key from Launchpad. How can i log with different account without password and only this key? thanks and have a great day
[16:11] <webchat24> is it better to delete this imported pub key and generate the pair private/pub direclty on the server?
[16:25] <mybalzitch> webchat24: the imported pub key lets you log in as that user to that machine from the identity you generated the pubkey with
[16:25] <mybalzitch> webchat24: you can create additional users after logging in, and import pub keys for those other accounts if you want
[16:26] <webchat24> is it better to have 1 key for each account? Or can i use 1 key for 2-3 account?
[16:28] <mybalzitch> depends on the level of security for the machines that hold the private keys
[16:29] <mybalzitch> just know that if you are using a pubkey for 2-3 accounts ,and that privkey gets compromised, then you have 2-3 accounts that someone can log in to, assuming they know where to attack
[16:31] <mybalzitch> until you revoke that pubkey on the server
[16:34] <webchat24> OK thank you a lot mybalzitch! Have a great day
[16:34] <mybalzitch> you too
[20:50] <znf> even if I set: 
[20:51] <znf> dhcp6-overrides: use-dns: false in netplan apply
[20:51] <znf> netplan*
[20:51] <znf> and set a nameserver manually, netplan still fetches the ipv6 dns server
[20:51] <znf> what gives?
