    sudo apt autoremove made system not bootable

    Hi,

    I use my computer for music recording. I recently bought a new computer and installed Lubuntu 20.04 on it. As part of setting up the computer I install a low-latency core to improve timing for audio recording.
    The command I use is:

    sudo apt-get install linux-lowlatency

    No problem there. The installation of the new core worked well and I could reboot. However, I did notice that the output of the installation process identified packages that are "no longer required" and recommended that they could be removed with "sudo apt autoremove".
    I did execute this command and afterward found my computer would not boot any longer.

    The splash screen for Lubuntu would show up for about 20 seconds, then the screen would go black. This much was normal.
    Normally, after about 15 seconds in the black screen, the mouse pointer would show up followed by the desktop a very short time later.

    The problem now was that the black screen (no mouse pointer) would never go away and the desktop would never be reached.

    I restored my system from a backup and installed the low-latency core again, but this time I did *not* execute the "sudo apt autoremove" and will not, as I am terrified it will make my system unbootable again.

    I'm trying to understand what happened.

    Here is a log of what the low latency core said was removable:

    It seems like some very important packages (i.e. video driver, etc.) are being removed. What gives?
    I am a long-time Linux user, but a novice on the technical side, so please forgive my lack of knowledge.
    Any help would be appreciated, as I think at some point I would like to remove unused packages...but SAFELY! Thanks.

    Thanks.

    From the list of packages, that was a bad plan, as you found.

    Installing linux-lowlatency doesn't, by itself, cause the package conflicts that would remove those important packages; I've done it myself many times. I suspect that you've removed something else previously that's put your computer in this state.

    Re: sudo apt autoremove made system not bootable

    The output suggests that at some point prior to the commands you had remove a vital piece of software somehow.
    As the command removed the xserver packages it's understandable that no muse or anything shows up, since those rely on the xserver for graphics.
    You might be able to fix it if you can switch consoles.
    Try ctrl + alt + F2, or F3
    and see if you get a prompt.
    If a prompt shows login as your user.
    And try installing the lubuntu-desktop package
    Try
    Code:
    sudo apt update
    sudo apt install lubuntu-desktop
    or 
    sudo apt install --reinstall lubuntu-desktop
    If it installed, I'd just try a quick reboot.
    (sudo reboot should work from that prompt.)

    The only issue that might come up is networking as I have not parsed the removed package list enough to gather whether any important networking pieces were removed or not.
    But it doesn't seem like there is.

    Re: sudo apt autoremove made system not bootable

    For some reason, a lot of packages were erroneously marked as automatically installed instead of manually (many packages installed during initial installation of the OS are marked as manually installed), or some metapackages depending on a lot of useful software were removed. Is there any clue in /var/log/dpkg.log?

    Have you considered Ubuntu Studio? It comes with software for audio processing and the low-latency kernel, so less stuff to do after the initial installation of the OS.

    Okay, I was successfully able to do carry out the instructions you suggested above, and rebooted the system. I am also on the internet (posting this) so I assume at least that part of networking still works.
    What would you suggest as the next step? Is there any way to check if this fixed the problem?

    By the way. I ran "sudo apt update again" (BUT DID NOT CONFIRM THE ACTION) and the output was much shorter:

    Re: sudo apt autoremove made system not bootable

    Your options are

    1) Ignore it and not run the autoremove command.
    (But this might not last long as the list will grow longer over time.)

    2) Painstakingly try removing each package listed one at a time and see if anything causes issues again.

    3) Just throw caution to the wind and run the autoremove command and hope for the best.


    I don't see anything that might be problematic in the output listed,
    but that doesn't mean there isn't.

    Re: sudo apt autoremove made system not bootable

    Okay. I will probably backup (disk image) then try sudo apt autoremove again.

    I wonder if the problem was caused by me having to remove LibreOffice (the one that was included in the Lubuntu 20.04 installation) and reinstall. This is due to a known bug whereby printing to PDFs results in a blank page.
    I followed the instructions in this thread here (link).

    Complete deinstall

    dpkg --list | awk '/ii/&&/libreoffice/{print $2}' | sudo xargs apt --yes purge
    sudo apt --yes autoremove
    sudo rm -r /usr/lib/libreoffice/*

    Reinstall

    sudo apt update --yes
    sudo apt install libreoffice libreoffice-gtk3 libreoffice-sdbc-hsqldb libreoffice-help-en-us
    I wonder if that stripped any important components then reinstalled them with the "manual" flag.

    Re: sudo apt autoremove made system not bootable

    I'm happy to report, deadflowr, that your advice seems to be the solution. After carrying out your instructions in post #3 and doing a "sudo apt remove" with the shorter list that resulted, my system rebooted fine and my system now shows:

    Code:
    brent@tower-i5:~$ sudo apt autoremove
    [sudo] password for brent: 
    Reading package lists... Done
    Building dependency tree       
    Reading state information... Done
    0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
    brent@tower-i5:~$
    Which seems like it's a good thing to me? RIght?

    The only "problem" with my system now is the buggy PDF export in LibreOffice (which is a noted problem in a french Lubuntu 20.04 install). The buggy version of Libreoffice was re-installed when I did the reinstall of Lubuntu desktop. I'm loathe to re-implement the solution found online as I believe that might have caused the problem in the first place.

    Re: sudo apt autoremove made system not bootable

    Before I run the autoremove command I always run it using the -s option (simulate) so that I have plenty of time to read the list of packages that would be removed without the -s.

    I do this because there have been times when third party packages that I need to keep would have been removed during the autoremove action.

    Re: sudo apt autoremove made system not bootable

    Your issue with LibreOffice seems to be the issue listed in the Lubuntu 20.04 LTS release notes. Did you try what is suggested there?

    https://lubuntu.me/focal-2-released/

    LibreOffice Exporting Documents as a PDF

    There is a bug where certain fonts do not render in exported PDF documents. As a workaround, LibreOffice applications can be launched from the command line with the following environment variable SAL_VCL_QT5_USE_CAIRO=true. For example, to launch writer issue SAL_VCL_QT5_USE_CAIRO=true libreoffice –writer.
