    What distro are you using? Can you do Recovery/Repair mode at boot?

    Try "Repair Broken Packages" first to see if it fixes anything.

    The try "Resume Normal Boot".

    G'day @T-buch and welcome to linux.org :)

    With the above screenshot, tapping your Space bar should select the line chosen, then Tab will take you to OK, and from there press Enter.

    Cheers

    God Morning (Here it morning)
    Somehow in my efforts to find the "secret key combination" - the computer rebooted. Now when running dbkg - I dont get the option to Update the "GRUB-PC". So how do I get back to get this option again - I think it was essential (to do the "GRUB-PC" Upgrading) cause my computer still boots into black screen
    The dialogbox I need was this (sorry its in danish)
    Sort skærm a10.jpg

    Translating; The Package will be upgraded. This menu allows you to chose which devices , if any - you want GRUB-INSTALL to automatically run for .....

    No.

    It doesn't help us to post screenshots, in what for most people is a foreign language. (Swedish?) Please try to give us text. That way we can use translation programs - unless you give English.

    Did you try what @wizardfromoz said? I run one distro. He runs many. He might be able to help you more than me. But be aware that Australia is in a much different time zone...

    First of all: There must be no doubt that I am very grateful that you try to help me!!

    I have already tried to translate:
    I can do what @wizardfromoz said, cause i do not have and can't get this dialogue box back any more (this is what I'm now asking for - how can I get that dialogboxs back, so I can do what @wizardfromoz said ;)

    Translating the dialog box:
    Sets up grub-pc
    GRUBs installation units

    Good morning (from DownUnder) @T-buch :)

    1. Do you (still) have a USB stick or DVD that you used to install Lubuntu in the first place?

    If so, we can likely use it as a rescue device to reinstall your Grub and get you running.

    2. If not, can you reproduce same from another computer?

    3. How are you communicating with us currently?

    Cheers

    OK, that's good :)

    The first thing I would suggest is to read the following article a couple of times

    https://linuxhint.com/ubuntu_boot_repair_tutorial/

    1. If you understand the steps you can follow those to try Boot Repair. It is written for Ubuntu but should work with Lubuntu (I don't have a Lubuntu on board or I would try it).

    If your Windows laptop has access to a Printer, you could print it first, or else after you choose the option "Try Lubuntu without installing", establish your internet connection, launch Firefox and follow the instructions "Live".

    2. If that does not work, we can use the same install stick to start a process called "chroot" which is a little complicated.

    I will be in and out a bit during my day, so if Step 1 fails, and given it is after 1:00 AM if you are in Denmark, I would try you with Step 2 when you are fresh. Actually, same really applies with Step 1 - your choice.

    Cheers

    Then Mommy are gone back home again with love ... ;)

    In the meantime, the computer has fixed itself - I can see in GRUB that it now has a version 15 and that must be the one it boots on by itself??

    The only thing left is that when I check the version in Terminal (lsb_release -a) I only get to say that it is a 18.10 (not a 18.10.15)

    hmmm

    Australians and Americans (and likely others, including your country) have sayings such as

    Near enough is good enough

    and

    If it ain't broke, don't fix it.

    :):)

    If it works OK for a time period of your choice eg a few days, read my Tutorial on Timeshift

    https://www.linux.org/threads/timeshift-similar-solutions-safeguard-recover-your-linux.15241/

    Once you have digested it, install Timeshift on Lubuntu, if you like.

    Ask any questions on TS there.

    Cheers
