When I did sudo netplan apply, it shows me permission warnings. Below are the same exact messages shown by the terminal.

** (generate:2496): WARNING **: 05:24:24.943: Permissions for /etc/netplan/00-installer-config.yaml are too open. Netplan configuration should NOT be accessible by others.

A clearer version for the stat netplan command: https://www.coderstool.com/cs/Yf7XHb

cat /etc/netplan/00-installer-config.yaml:

network:
  ethernets:
    enp0s1:
      dhcp4: true
  version: 2

I have continued with "sudo systemctl start isc-dhcp-server" , "sudo systemctl enable isc-dhcp-server", then "sudo systemctl status isc-dhcp-server". Below are the results of the commands.

That's strange - permissions look correct compared to my system.

I have attached the Stat netplan command results. I'm so lost right now. I can't seem to configure it... T.T

What's not working? You know it's only a warning, right - it's not an error..

The status of my dhcp server has failed once I have done with configuring the netplan configurations. I have updated my question. Feel free to have a look. Also, thanks a lot for your replies!

the DHCP servers may be unrelated. What happens when you start it manually? I *suspect* that the order the services are started in are 'wrong' - but I just ended up going back to the classic /etc/networks setup before I got around to digging further

Also "Cannot call openvswitch: ovsdb-server.service" is not running. seems worth focusing on

Try `sudo chmod -R o-rwx /etc/netplan/`, which removes access of "others". Can it be that this is Ubuntu in a virtual environment or similar ?

I have the same permissions on my `01-network-manager-all.yaml` and when I do `sudo netplan apply`, it gives me the same warning (four times). Nevertheless, the network works fine.

chmod 600 /etc/netplan/your_config_file.yaml should solve your problem. Do this for every netplan file that was listed in the warnings.

It says operation not permitted. How do I get around this?

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.
