    nunchuckmadness; Uh Huh

    Yaml files must be exact. We best see what your present file is !
    Unfortunate for you - I do not run network manager thus I can not directly check all your files.
    However, we can start the looking.
    Code:
    cat /etc/netplan/01-network-manager-all.yaml
    and make sure !
    The desktop install -not SERVER - should be this:
    Code:
    # Let NetworkManager manage all devices on this system
    network:
      version: 2
      renderer: NetworkManager
    This - even to the tab/spaces - must be exact !

    nunchuckmadness;

    Ok next up is:
    Code:
    ls -al /run/systemd/network/
    do you see similar:
    10-netplan-enp4s0.network
    where *my* interface is known as "enp4s0" - yours may well be different.
    Mine looks like:
    Code:
    [Match]
    Name=enp4s0
    
    [Network]
    DHCP=ipv4
    LinkLocalAddressing=ipv6
    
    [DHCP]
    RouteMetric=100
    UseMTU=true
    also is the symbolic link present:
    Code:
    ls -al /etc/resolv.conf
    such as my result:
    Code:
    lrwxrwxrwx 1 root root 39 Apr  3  2018 /etc/resolv.conf -> ../run/systemd/resolve/stub-resolv.conf
    looking for that goof - somewhere

    ls -al /run/systemd/network/

    Comes back with no such file in directory

    ls -al /etc/resolv.conf

    Looks like yours.

    Just an idea.

    For all these commands, you can send the output to a file, then copy the files to a USB flash drive, then connect that to your laptop and post the files here.

    For example,
    Code:
    $ cp /etc/netplan/01-network-manager-all.yaml /media/FLASH_DRIVE_NAME/
    For commands, just use the redirection of stdout to a file:
    Code:
    $ name-of-command -options -more-options > /media/FLASH_DRIVE_NAME/command-out
    And if you'll put the command and output between forum code tags, like I did above, it is easier to read for us. We are used to monospaced fonts. It also means you don't need to format any of the output from the terminal/console.

    There's a system-info script which you can grab on your laptop, put onto the flash drive, copy over to your HOME on the Ubuntu system and run. The output from that command can be copied back to the flash drive, posted here (code tags please), and then we won't have to ask for specific piece of information. https://github.com/UbuntuForums/system-info is where to get it and has instructions for running it. It is a good tool to have on any Linux system for troubleshooting.

    If it were me, I'd use the mount command with specific options based on the file system on the USB partition and the current device name, which can change. But that is probably another rabbit-hole that you don't want to go into if you don't have that knowledge already. OTOH, if you boot off a flash drive into a Try Ubuntu environment, then you will have a GUI and can connect a different flash drive to the system to copy off the files using a GUI.

    Fixing booting issues is easiest for the widest possible boot issues from a Try Ubuntu environment. Also, you can add the PPA for boot-repair, install it, then run it from that Try Ubuntu environment and probably upload the information since networking will probably work too.

    Re: Can't find any info that helps, updated ubuntu JellyJam and now it won't boot gui

    nunchuckmadness; Well !

    Triple check that " /run/systemd/network/ " does not exist - typo ?
    as:
    at boot-time netplan 'renders' a systemd-networkd config in /run/systemd/network/ - check there are files in there. If not, then there is no active network config.
    netplan is a configuration generator, for either NetworkManager, or systemd-networkd.
    the idea is to create a config in /etc/netplan that is then applied automatically to whichever service manages network connections [/etc/netplan/config.yaml] - network manager -> /etc/netplan/01-network-manager-all.yaml
    If you tell Netplan to use NetworkManager, all interface configuration control is handed off to the GUI interface on the desktop.

    which way did he go, George
