Arch wont boot

kreshta · 2017-10-13 11:17:04

Hello,

I know that this question appears a lot and I don't know what type of information you need but basically, Arch wont boot. I can get to syslinux and if I choose windows everything works as expected. But, when I choose Arch the last line that I see is

 [  OK  ] Started Hostname Service.

After waiting a while, I just restart the computer. I don't know what information I can give that would be helpful so I will list anything that I think is relevant.

I have been successfully running and booting Arch for about 3 months
I ran sudo pacman -Syu to update to kde 5.11 (and booted a few times) before the issue
It normally takes seconds to shutdown but the last few times took about 3 minutes (it was stuck on 1 thing)

If there is any other information that I should ask then I will.

Thanks

Can you change to another tty after booting (Alt-F2, Alt-F3, or Ctrl-Alt-F3 in case X started but the screen just isn't being redrawn for some reason).

If not, can you boot to multi-user.target? Or rescue.target?

If you press alt+f2 when the hostname status appears, do you get to a log in prompt? If so, log in as root and upload the journal for the current boot session.

https://wiki.archlinux.org/index.php/Li … in_clients

If you don't get to a login prompt, reboot to rescue.target and upload the previous boot session's journal.

Paste the link to the journal here.

Thank you for your responses. I am not sure how to upload the journal. When running journalctl I get this: https://image.ibb.co/fCuJab/DSC_0217.jpg

Please see the wiki on how to upload and share logs from a tty.

Also, can you let us know whether changing ttys was sufficient, or did you need to change the boot target?

I pressed alt+f2 and logged in. How can I change the tty? I ran

journalctl | curl -F c=@- https://ptpb.pw/

and got

curl: (18) transfer closed with 26 bytes remaining to read

Could it be that I am not connected to the internet?

From your screenshot, it looks like you are booting an outdated kernel (4.12.8 is from August). Please could you upload your /var/log/pacman.log as well.

EDIT: Crossposted with the above.

Putting aside the log uploads for a moment. Please post the output of

pacman -Q linux

Side note: You changed tty when your pressed alt+f2. You moved from the boot log tty (presumably tty1) to a login prompt on tty2.

pacman -Q Linux returns
linux 4.13.5-1

I am not sure why I cannot upload the log but the start of it is here

I don't think it's a coincidence that your booted kernel is from the same sort of time as your initial pacstrap installation. How did you set up your partitions? Did you create a separate boot partition, but then forget to add it to your fstab?

The problem is that you have booted a kernel (4.12.8) which doesn't have any modules available on your root filesystem (you have the modules for 4.13.5). This disconnect between your kernel and modules needs to be resolved. I would suggest downgrading your installed kernel package to 4.12.8 (assuming this pacakge is still available in your pacman cache), then mount your boot partition, then update your kernel again, update your fstab, and reboot.

Thank you for the suggestion. I will read up a bit on what I am doing and how to do it and then I will attempt to do what you wrote.

Okay, so here's an update.

I think that my issue is a known bug: https://bugs.archlinux.org/task/55960 . There are 2 workarounds that I found.
1) change to tty2 by pressing alt + f2 , logging in, typing startx
2) add to /etc/systemd/system/sddm.service.d/override.conf a sleep of 3 seconds by writing

[Service]
ExecStartPre=/bin/sleep 3

causing the race condition to not occur (at least for the few times that I tried.

Thanks for all your help. (Do I mark this as solved?)

You may be experiencing that bug as well, but you should still address your kernel/boot partition issue.

I'm not sure where you found the second workaround, most people who want to continue using sddm are just enabling early KMS.

However, if you have solved your problem to your satisfaction, then you can mark your topic solved by editing the first post and amending the title.
