I'm very new to Ubuntu. I installed Ubuntu Server 20.04 LTS on an old laptop, which doesn't have an ethernet port.
Upon installation, I wasn't able to proceed past the network configuration stage with the WiFi connected, or else the installation would crash. So I proceeded with the installation without the connection to WiFi.
Now I'm having trouble enabling wifi and configuring my network. Can someone please provide some guidance on how to do this via USB stick? Below is what I've tried already:
I tried to install net-tools via the sudo apt install command, but since there was no connection, the system could not download the necessary files.
I've since tried modifying the sudo nano 50-cloud-init.yaml file in the below format (with my network details)
wifis:
wlan0:
dhcp4: true
optional: true
access-points:
"SSID_name":
password: "WiFi_password"
but when I apply it, I get an error that tells me
a dependency job for netplan-wpa-wlan0.service failed. See 'journal -xe' for details
