• Failed to start Pamac / Started Light Display Manager


    Hi to everyone :)
    Is my first post here and I have installed and using antergos /-or linux for over a year now. Before I was using Windows. The reason of swapping was Win10

    I do not know much about programming/developing but I get on managing/fixing the issues of my pc/laptops my self for many years.
    Yesterday on starting the laptop there were 47 packages to be installed -which I did (I think there was an upgrading of “thunderbird” as well) after mentioned installing - I wanted to check my emails on “thunderbird” but it was not starting/opening (I am mentioning this only for my chronological steps that I have taken - “thunderbird” might not be the problem at all)…
    After this I did a restart…and this is my question/main issue:
    When booting on first line it comes:
    "Failed to start Pamac"
    and then for eternities
    "Started Light Display Manager"
    and again and again on the the new line below - the booting never ends

    Is it with ctrl+alt+f2 where I can give orders to the console on booting the laptop?
    how are the exact steps here?
    Thank you in advance for your suggestions :)

  • [ctrl+Alt+F2] = TTY2 then you can login as normal user or root …

    journalctl -b -0
    

    will give you all what happens on last bootup.

    journalctl -b -0 | grep failed
    
    journalctl -b -0 | grep ERROR

    Thanks joekamprad … It was not possible to put in any command like above you suggested i.e. ctrl+ALT+F2 does not work (although in the past I could used it ) then I tried to get into command shell through GRUB2 - but neither no success.
    All I can say when it starts booting it says"Failed to start Pamac"
    And then on next lines:
    “Starting Light Display Manager”…“Started Light Display Manager”
    “Removed slice User Slice of Lightmanager”… Stopped Light Display Manager .ession C01 (on next flashing C02 …and so forth)
    “Started UID Manager for UID 620… Stopping UID Manager for UID 620…Stopped UID 620 Manager”

    and this goes for eternities - (on each line with screen flashing)

    Thanks…

  • Then LiveIso boot and chroot into HD system is what you need to do.
    { @Community-Moderators we do nopt have a rescue-chroot WIKI entry? TODO }

    -boot Antergos-Live-Iso
    -open a terminal

    For EFI Systems:

    # sudo su
    /mnt /dev/sda3 /mnt
    /mnt /dev/sda2 /mnt/boot
    /mnt /dev/sda1 /mnt/boot/efi
    arch-chroot /mnt
    

    Now (inside this terminal session) you are inside your Installed Antergos and can do the rescue:

    # pacman -Syu
    

    update the system

    journalctl -p err -b
    

    show errors/fails/warnings from last boot

  • Just to confirm… as I wrote so much :)
    The initial problem still not solved…

  • Do you boot with grub/bios-mbr / grub/efi or systemdboot/EFI ?

  • @joekamprad
    To be honest I am not sure.
    Since I have this problem, I can not get ( when booting) to the BIOS Sector.
    I have an SSD HD - and last time I was on the BIOS Sector was when I installed Antergos. This was one year ago… if I am remember correctly then I got the option to choose.
    Today when I booted with a Live-ISO … it was with a CD-Room
    Thanks - although I m not sure if my answer was of help…

  • from inside chroot:

    cd /boot
    ls
    

    Or send a screenshot from the /boot directory you can open also with gnome-files from the LiveIso (other places)

  • But you havent clean up after the upgrade from gstreamer…

    gstreamer0.10 is old and unusable.

    pacman -Qs gstreamer0.10
    

    uninstall all this packages:

    # sudo pacman -Rsnc gstreamer0.10-....

  • @joekamprad good evening

    - gstreamer has been removed (17 files)

    But this could also be the problem

    -May 01 16:35:55 ant-16.4 systemd[1]: lightdm.service:** Two services allocated for the same bus name org.freedesktop.DisplayManager, refusing operation.**

    [[email protected] boot]# ls
    grub memtest86+ syslinux

    Is the above ok concerning the booting files?

    Many Thanks

  • gstreamer0.10 is old version newones needs to be installed vs. gstreamer (1.10)

    $ sudo pacman -S gstreamer gstreamer-vaapi gst-plugins-bad gst-plugins-base gst-plugins-good gst-plugins-ugly
    

    This Error about lightdm shouldnt be permanent, may you need tu update the system with

    $ sudo pacman -Syyu
    
    ╭─[email protected] /boot  
    ╰─➤  ls
    grub                        
    lost+found
    initramfs-linux-fallback.img             
    vmlinuz-linux
    initramfs-linux.img                        
    

    should it looks with Grub.
    You have syslinux installed?

    pacman -Qs syslinux

  • @joekamprad
    Good Afternoon,
    I haven’t done yet what you did propose on you last post… first I would like to draw your attention to this points:

    1.) In order to do all the modifications in the console (pacman)…
    Is it necessary to do the below mountings?
    I admitt that I haven’t done it yet - As I was not sure about the mode of my booting.

    sudo su

    /mnt /dev/sda3 /mnt
    /mnt /dev/sda2 /mnt/boot
    /mnt /dev/sda1 /mnt/boot/efi
    arch-chroot /mnt

    2.) Because I cleaned yesterday gstreamer (17) - in the console (Live -ISO / CD)…
    … and when I do a reboot it looks that they are still there - as I can remove them again… it looks to me as they are still there… perhaps the above point one is the reason.
    .
    Thanks for all

  • Sorry but i think this chrooting with efi does not matter as long as you do not need to write boot images -e-t-c-
    But if you remove gstreamer0.1 from normal Terminal without chrooting into your hd it is only inside the LiveSession.

  • We have some confusion here.
    What you show me from inside /boot is then also from LiveIso.
    you need to show what is on your system hd inside boot or do a:

    $ sudo fdisk -l
    

    from normal terminal without chrooting before, outside the LiveIso environment then.
    It will show all partitions.

  • great ;)
    So a LVM encrypted system, thats something i never do …#
    You will need to open the encrypted volumes and then mount them… to chroot into it…
    I think lsblk will give a better overview as fdisk -l
    But looks like /dev/sda is ANtergos and /dev/sdb is another Linux install?

  • Not encryped and Antergos is /dev/sdb then:

    sdb1 = EFI-boot
    sdb2 = /boot
    /dev/mapper/AntergosVG-AntergosRoot = /

    sudo su
    mount /dev/mapper/AntergosVG-AntergosRoot /mnt
    mount /dev/sdb2 /mnt/boot
    mount /dev/sdb1 /mnt/boot/efi
    arch-chroot /mnt
    

    should do the job ;)
