Hello everyone, newbie here. I would like to give my node a name and tried to follow this guide. I did upgrade my node to 0.5.0 . Before, I was able to see the directory when I ssh -t using the terminal.
This command shows a blank box: Open the config file sudo nano umbrel/lnd/lnd.conf
The directions clearing states to make sure its under the " Application Block".
Need help, please advise. Thanks 
--------The directions I am following below.
Want to set an alias for your Umbrel 6 Node?
Follow these steps:
- Log in to your node using SSH 254. Usually this means opening a terminal and typing ssh -t umbrel@umbrel.local. The user is umbrel. Default password is moneyprintergobrrr for older versions of Umbrel. New versions use the dashboard passord. When typing your password you usually see nothing (for safety).
- (Optional) change your default password by typing passwd
- Open the config file sudo nano umbrel/lnd/lnd.conf . lnd is small for LND, there are no i’s. It will ask you again for your password (same as before), and you will again not see you entering the password.
- You are now in the editor. Add alias=SOMENAME. This must be added to the first paragraph. Somewhere below the block [Application Options], not in a different block.
- (Optional) set color=#ff0000 or any other hex color, on a new line, just below alias. find a nice color 262.
- You will see the commands you can give at the bottom. The caret ^ means CTRL button. ^X is eXit, so use CTRL-X to exit the file. Confirm you want to save the buffer using Y. Press enter for file name (don’t change).
- After you have exited the editor, type cat umbrel/lnd/lnd.conf to look at the content of the file.
- Then restart your Umbrel node. You can do this properly from the Umbrel web interface (Settings, Restart)
(click the 3-dots in the top-right).
