For the past few hours I have been following to official Ubuntu guide to setup an Ubuntu server on my Raspberry Pi 3B+ however whenever I boot up the server and sign in it doesn’t connect to the internet, I’ve follows the official guide to fix the sudo nano /etc/netplan/50-cloud-init.yaml file and reboot but nothing will work.

Edit:

Output of lsb_release -d:

Please update question with output of `lsb_release -d` and `ip a` and `cat /etc/netplan/50-cloud-init.yaml`

Telling us which remote procedure (RP) you "followed" doesn't help us help you for N reasons: 1) It's remote. Will the link exist tomorrow? 2) Reading the RP doesn't tell us how accurately you "followed" it. Did you suffer typos or missed lines? We have. 3) Reading the RP omits the error messages **you** got on **your system**. These error messages (and the commands that caused them) are key elements in any diagnosis.

Look at the network logs with the terminal command: `sudo journalctl -b 0 -u NetworkManager`. Read `man journalctl`.

So it looks like you’re trying to setup wireless. Two things…indentation is very specific with Netplan YAML files. Do not use tabs. Use spaces only. Next, your wireless network and password need to be enclosed in quotes. See [here](https://askubuntu.com/a/1107570/1684306) for an Ask Ubuntu answer to a similar question.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
