Crash at the end of update has messed up kernel. Any ideas?

[acurrall]

Hi folks, I was just running the latest update, from the GUI. It was a really long download - maybe a couple of hours - and my machine crashed at the very last minute! When it automatically restarted I just get the GRUB options screen and neither of the two offered work. They throw up the message:

error: file ‘/boot/vmlinuz-6.1-x86_64’ not found.
error: you need to load the kernel first.

Press any key to continue…

So, I’ve chrooted from a live usb stick and ran the following in Terminal:

Any advice will be greatly appreciated. Thank you.

failed to synchronize all databases (unable to lock database)

Before updating in chroot environment remove the database lock:
sudo rm /var/lib/pacman/db.lck
If you get: cannot remove ‘/var/lib/pacman/db.lck’: No such file or directory; use this:
sudo rm /var/tmp/pamac/dbs/db.lck

[acurrall]

Thanks for the suggestion. Sadly, I just get this same error message at the end of the mirror list:

::INFO Mirror list generated and saved to: /etc/pacman.d/mirrorlist
:: Synchronizing package databases…
error: failed to synchronize all databases (unable to lock database)

[Wollie]

Then try
sudo rm /var/lib/pacman/sync/*.*

If this doesn’t help I would suggest to check all what is provided in these wiki pages:

[HowTo] Recovering from an interrupted update/upgrade

Difficulty: ★★☆☆☆ So you couldn’t wait until the update process had completed and you went for the reset/power button, didn’t you? And now you’re getting the message that you don’t have a kernel installed. Well, you’re not the only one — we’re seeing it happen all the time. So, here’s how to fix it, you impatient n00b. If you don’t happen to have a recent Manjaro installer USB/DVD/CD handy, direct your browser to this wonderful page, download t…

Ha ha! Ive been here before!

I followed the advice on the above link and now it boots in a user and password screen with the message
The current theme cannot be loaded due to the errors below, please select another theme.

file:///usr/share/sddm/themes/breath/Main.qml:26:1: plugin cannot be loaded for module “org.kde.plasma.core”: Cannot load library /usr/lib/qt/qml/org/kde/plasma/core/libcorebindingsplugin.so: (/usr/lib/libKF5QuickAddons.so.5: file too short)

I hope I haven’t made any typos there. I had to copy it out as it wouldn’t let me copy and paste.

Ive had this theme problem before, only with a different error message, and I think @brahma helped me sort it out. Hopefully, he’s listening in now…

[Wollie]

Had you installed any -git packages for plasma/KDE components? Or any other tinkering?

[acurrall]

Not that I can recall.

Here’s the error message at the end of the last bash:

Have you tried replacing/restoring Grub?

• Restore the GRUB Bootloader

This may be sufficient to allow booting to a TTY, after a reboot.

From there you could attempt to update again, if the theory holds true.

No other wizzardry comes to mind.

[acurrall]

Okay, I managed to get a TTY.
I ran pacman -Qm and got this
transcode 1.1.7-41
Is this the problem?

[varikonniemi]

file:///usr/share/sddm/themes/breath/Main.qml:26:1: plugin cannot be loaded for module “org.kde.plasma.core”: Cannot load library /usr/lib/qt/qml/org/kde/plasma/core/libcorebindingsplugin.so: (/usr/lib/libKF5QuickAddons.so.5: file too short)

Seems like the installed file might be corrupt, to fix it reinstall the package that provides said file.

[acurrall]

Aha! Thank you! Any suggestions how I can do this from a TTY?

[varikonniemi]

Check with pacman or google what package provides the file(s) it complains about, and pacman -S that package.

[acurrall]

Thanks, I’ll try that!

[varikonniemi]

You can also try sudo pacman -Qkk to check all files to see if you possibly have other corrupted packages that are not immediately obvious.

[acurrall]

Loads of error popping up but scrolling by to fast to clock.
Id like to try installing the package libKF5QuickAddons.so.5
Could anyone advise me on how to do that from a TTY, please?

[cfinnberg]

$ pacman -Qo /usr/lib/libKF5QuickAddons.so.5
/usr/lib/libKF5QuickAddons.so.5 is owned by kdeclarative5 5.111.0-1

So

sudo pacman -S kdeclarative5

[varikonniemi]

You can scroll up to read the output, right?

Also, did you try “man pacman” ? It shows you how to use it, like Query owner of provided file. Cfinnberg already provided the spoonfed solution, but trust me, putting in a bit of effort to learn it for yourself will have it stick as knowledge. Just copypasting code others provide you will have you forget it by tomorrow.

[acurrall]

Thank you, cfinnberg and varikonniemi, I do try to learn the logic behind what I’m copy & pasting. I have already come a long way with very little knowledge to start with. I’ve learned so much thanks to the generous spirit of this forum. Sometimes it just takes so long to get a desktop back again though and, when I have urgent work to finish, I panic and just want to get it fixed. I’ve pieced together a lot in previous inquiries just by searching the forum and attempting to apply elements of the solutions to others’ problems to my own. Hopefully, the eventual fix to this will help out some other searcher in the future.

[acurrall]

Just dipping into the PACMAN manual now. Wow! Thanks varikonniemi. I wish I’d known about this before!
