My new Ubuntu Install isnt working properly

  • 772

I just installed Ubuntu Server on my old laptop in hope of creating a home server, but ive noticed multiple commands that worked natively on other machines didnt work on this one, requiring and apt install. And when I did that, it gave out errors when fetching from the ubuntu archive website. I figured it was because of internet related issues, but when i checked the network cards (Ethernet) it was disabled, and after enabling it, it would just get disabled after reboot again, and couldnt install the libs still. On my routers configuration website, it says the port is connected (Green) but no hostname is provided. I tried adding the random mac address that was popping up into my reserved DHCP addresses but still trying to ssh that with the networks hostname wouldnt work. If any further info is needed i can provide it.

Edit:

    Just stop your cloud-init by doing:

    sudo nano /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg

    Then typing:

    network: {config: disabled}

    Inside the file and pressing Ctrl+X, then Y, then ENTER to save the file. After that, do:

    sudo nano /etc/netplan/50-cloud-init.yaml

    And insert inside the file, these configurations:

    network:
version: 2
renderer: networkd
ethernets:
    enp2s0:
        dhcp4: true
        dhcp6: true

    Then, run:

    sudo netplan apply

    To apply the changes. After all that, reboot to test with:

    sudo reboot

    And:

    ip a
