when I input this in the terminal, it asked about a fingerprint and if i was sure i wanted to connect, I said yes and now I am no longer able to input any further commands, is there something I am missing or a different way to achieve this?
Yes, follow the instructions in the screen. It says what you have to do.
I beleive you have to enter the password at the prompt
umbrel@umbrel.local’s password:
(it doesn’t show when typing the password).
And depending on the version of umbrel you are using the older one uses : “moneyprintergobrrr” .
What is the purpose to change the user name? it’s to replace umbrel to login in ssh, that’s all? I did change it thinking it would be my node name, and then find out above that what I was looking for was to change my node alias (and that it’s not recommended).
Should I set back my user name to umbrel or can I leave the new one it doesn’t matter much?
Totally useless. That name is meaningless, generic.
But noobs are confusing it with node public alias name. That is totally other thing.
Ok I will leave it then. I’m one of those noobs, if it’s useless, why it’s mentioned here? At least you could add a line saying that it’s useless so we don’t bother trying to change it.
Because are obsessed with changing useless names 
I was reading the code of Umbrel, and seems all local IPs adresses and names are hardcoded (fixed in the code), so, to run another instance of umbrel in same local network, you’ll have to change some configure files, for every new install, or you will get lots of IP conflicts.
No, why are you complicating things when are so simple.
- Set a static IP for each node machine
- Use the each IP to access your nodes or just add in your local PC hosts file a different name for each node, like umbre1.local and umbrel2.local
Done. No complicated changes into node code.
The same happened to me and i am still not able to open umbrel.local. Can somebody help us. We are new to this. I know that there are a lot of very intelligent people here that will help the ones than need the most help.
Try the IP instead of umbrel.local
ssh umbrel@IPADRESS
which you will find logging into your modem / router which gives IPs to your devices. See Darthcoins other post 1. Set a static IP for each node machine
Can you run an umbrel node on a raspberry Pi 4 that has installed Raspberry Pi OS ? Or will it erase it ?
Umbrel has its own OS, UmbrelOS (a debian base modified for Pi and node stuff). Yes it have to erase the mSD (when you flash it with Balena). Also the SSD drive should be just an empty drive, no partitioned, no formatted.

My Umbrella Note’s 100% synchronised is done. What should I do next because he is doing zero Satoshi show in my account.
The channel is also not opening, because there is no balance in my account, so what should I do and how will the balance come?
Plz helppppp 
Hi @mahesh
You need to send BTC/Sats to your node. once the transaction has been confirmed by the blockchain, you can open channels to other nodes.
You will find many channels on the homepage of 1ml.com. You are also welcome to open a channel to me. as soon as you have enough remote balance, I like to rebalance the channel. my address is:

Thanks for reply
I thought I would earn some money.
as you mentioned i need to buy some satoshi
If I have to buy some satoshi Then what will I gain from this node?
You will never really make a profit. the channels cost money, the node consumes electricity and has also cost money. the few satoshi you can earn will NEVER cover your costs. We do all this FOR bitcoin and build a simple payment method.
