I broke it :(

One of my Ubuntu server machines won't boot, I know I shouldn't be asking here but I know we have some linux pros in here.

Don't suppose anyone could give me a hand over discord pretty please?

    Well depends - what for a server home or cloud.
    Do you have a backup system which boots (for Chroot)?
    What do you think is the reason for the problem?

    Yeah, 'doesn't boot' will get use nowhere
    Kernel panic? No boot device? Starts but can't reach?

    Sorry been trying to fix it.

    Turned out it was failing at mounting a windows share at boot.

    For some reason it can no longer contact anything on the network via hostname without FQDN.

    Strange :(

    Cheers tho guys

    Sounds like resolv.conf got rewritten.

    Check the output of:

    dpkg -l | grep -i resolvconf

    There will probably be a line that begins like this:

    ii resolvconf

    That means that any changes you want to persist past a reboot in your DNS search path need to go into:

    /etc/resolvconf/resolve.conf.d/base

    ...in the following format:

    search blarg.org
    nameserver 1.2.3.4
    <more nameservers>

    My guess is that you used a graphical network config app to set your search path, which just hamfisted resolv.conf, ignoring the fact that resolvconf, a default package in Ubuntu now, overwrites it every time the network is brought up.

    I did get that response. I have added both the dns servers too base, so does the resolve.conf just get ignored?

    Not really, read the description about the problem again :)

    Then I'm guessing NetworkManager is handling your name resolution.

    I've read it five times now, and yeah, it looks like the problem I described. Non-FQDN local hostnames are not resolving. What would you say is the problem in that case?

    Tried running

    nmcli device and get

    Error: nmcli (0.9.88) and NetworkManager (unknown) versions don't match.

    Right to assume this could be the issue? Remove network manager?

    After you made the update to base, did you reload resolvconf? Make sure you do that. If that works (ie: the host resolves) then you won't have to mess with NetworkManager at all.

    ...but for the record, I do remove NM every time I start using a new install.

    There's always something fucking with resolv conf
    Set it to +i and be happy

    Ha, that's what I used to do. Kind of like shoving a paperclip into the CD-ROM to get your game CD out when it wouldn't eject.

    Just removing NM seems to have done it :) thank you :D
