Incomplete Update Led to Error in Locating Kernel

Hello.

I recently tried updating my Manjaro system (KDE) to the latest version but found, even after a night, that it was stuck running post-transaction hooks. I read online that it was fine to ignore it and so shut the laptop down. Big mistake, I know now.

Anyways I logged in and got the following nerror message:

error: file ‘/boot/vmlinuz-5.12-X86-64’ not found you need to load the kernel first

I read online that you need to complete the installation using a live USB, but that hasn’t worked very well so far (at least in the direction I took it). So I followed the instructions listed here but found that I was stuck trying to move the pacman dB file. Worse still, whenever I boot my laptop, it goes straight to UEFI settings, and changing the boot order of the OS locks it there. Would greatly appreciate assistance in this regard. I’ll provide any extra details if necessary.

Thank you

Edit: Please find the output of some commands I’ve run below:

Were you able to successfully manjaro-chroot -a?

After chroot, did you run pacman -Syyu? If it failed, what is the output?

Yes I could.

Here is the output for manjaro-chroot -a:

grub-probe: error: cannot find a GRUB drive for /dev/sdb1. Check your device map.

==> Mounting (ManjaroLinux) [/dev/sda4]
    --> mount: [/mnt]
    --> mount: [/mnt/boot/efi]
mount: /mnt/etc/resolve.conf: mount point is a symbolic link to nowhere.

And here is the output for pacman -Syyu

error: failed to synchronize all databases (invalid URL for server)

Apologies but the three ellipsis just stand for output that’s similar to the error: failed retrieving file 'core.db' from mirrors.colocall.net : Could not resolve host: mirrors.colocall.net warning: too many errors from mirrors.colocall.net, skipping for the remainder of this transaction output. It tries retrieving core.db from various sources, but ultimately that doesn’t work for any of them.

Any help would be appreciated.

If mirrors are out of sync then update them first:
sudo pacman-mirrors -f5

then update
sudo pacman -Syyu

I think the DNS configuration in chroot is wrong.

You could try to set it to 1.1.1.1 manually, then do the update.
Don’t forget forget to reset it after it booted successfully.

Hello. Thanks for the advice. The mirror list was updated successful, but upon running pacman- Syyu I received the following:

error: failed to synchronize all databases (invalid url for server)
 code here

It says the internet connection appears to be down. But that obviously can’t be from my end since I’m using it right now. Is there some other issue?

Is your username manjaro? You must execute this inside the chroot environment.

Well, do you have internet access in your chroot/live environment?

Inside (!) the chroot, you can move the /etc/resolv.conf:

mv /etc/resolv.conf /etc/resolve.conf.backup
echo "nameserver 1.1.1.1" > /etc/resolv.conf
pacman-mirrors -g -f5
pacman -Syyuu

If you don’t see that the initramfs was run:

mkinitcpio -P

(It doesn’t hurt if you don’t know if it ran before, if in doubt, just run it.)

If this worked, you should move back the old /etc/resolv.conf:

mv /etc/resolv.conf.backup /etc/resolv.conf

First of all I’d like to thank you very much for your help so far.

I’ve done this and updating became possible again. A few things though:

This is the output for pacman -Syyu in chroot

[manjaro /]# pacman -Syyu
:: Synchronizing package databases...
 core                  166.2 KiB  31.7 KiB/s 00:05 [##################] 100%
 extra                1889.4 KiB   174 KiB/s 00:11 [##################] 100%

 multilib              174.0 KiB   260 KiB/s 00:01 [##################] 100%
:: Starting full system upgrade...
 there is nothing to do

However, mkinitcpio -P yields the following output:

[manjaro /]# mkinitcpio -P
==> ERROR: No presets found in /etc/mkinitcpio.d

And mv /etc/resolv.conf.backup /etc/resolv.conf yields:

[manjaro /]# mv /etc/resolv.conf.backup /etc/resolv.conf
mv: cannot stat '/etc/resolv.conf.backup': No such file or directory

The incomplete update that started all of this isn’t completed, and when I try booting the computer without the liveusb, it still boots into the bios screen. So I figure there’s still something missing. COuld I have some assistance in that regard?

can you provide the output of
pacman-mirrors

So that i can check if the mirrors you are using have synced.

@Thenujan thanks.

I think the mirror issues are resolved since I just updated using pacman -Syyu recently but you can find them below:

[manjaro /]# pacman-mirrors
Pacman-mirrors version 4.23.2
Local mirror status for stable branch
Mirror #1   OK  06:45   United_Kingdom  https://mirrors.gethosted.online/manjaro/repos/
Mirror #2   OK  00:45   Ukraine         http://mirrors.colocall.net/manjaro/
Mirror #3   OK  07:54   Portugal        http://ftp.dei.uc.pt/pub/linux/manjaro/
Mirror #4   OK  07:54   Pakistan        https://repo.inara.pk/manjaro/
Mirror #5   OK  02:47   South_Korea     https://mirror.funami.tech/manjaro/

You could try the reinstallation of the kernel:

pacman -Su linux515

(However, I still doubt that you are actually inside the chroot but in the LiveUSB.)

This worked. There are some side effects but the Manjaro is useable now at least. Thank you very much.

Do you have any backup you could restore now you have a booting system? Im surprised you have any side effects but you could restore a backup and then run the update properly

No. Never took backups too seriously because I couldn’t be bothered to learn how timeshift worked. That’s not the case after this though. Am creating a backup now.

The only side effect was that the grub bootloader turned off. But that was easily fixed. Boot and shutdown times also seem worse.
