Struggling to Use Text Editors on Ubuntu Server for Wi-Fi Setup

It sounds like you might have installed the minimal version of Ubuntu. Check if the vim.tiny package is installed. If not, you can also modify the netplan settings directly using the `sed` command or even redirect the output from `cat` or `echo` into the file if you really need to edit it.

Just a heads up, netplan itself isn't a text file you edit directly; it's a program that manages network configurations. Since you're on a server version with no GUI, you can try running `ifconfig` in the terminal to see your network devices, and then use `nmcli device wifi connect password ` to connect to your Wi-Fi. If your laptop is older, consider switching to Xubuntu as it has a lighter desktop that can work well as a server.

If you're getting 'command not found' errors, it might be time to install the necessary commands! Also, if you're new to editing text files in the terminal, you can try using `nano`, which is pretty beginner-friendly and likely already installed.

You should definitely give `nano` a shot for editing text files. It's really straightforward to use, and you probably have it available on your system already.
