[SOLVED] Pacman -Syu Crashed - Got Issues

Hi All,

After a couple of days searching for answers I now seek everyone's help.

Running 6.9.6-arch1-1 Plasma 6.1 Nvidia + Wayland - all working perfectly before.

On the 25th this month I ran

 Pacman -Syu 

which got half way through and then my monitor suddenly went blank and keyboard was unresponsive. After waiting some time I did a hard reset. I booted fine into my desktop but now I can't open Konsole, Timeshift, Ksystemlog, my clipboard also shows 'stuff' in it yet it's empty.

I checked Pacman logs using tty - and on the 24th it says my locale is not set and its reverting to default "C" - then on the 25th it shows a whole bunch of packages (mainly qt6 stuff, kwin, libjuice etc etc) 'upgraded' - right before the crash.

 Pacman -Qk 

shows these packages as empty folders with no missing files.

from the journal I have

 user@1000.service Missing 'D-Bus Service' section in service file '/usr/share/dbus-1/services/org.mate.panel.applet.MateXAppStatusAppletFactory.service'

user@1000.service Missing 'D-Bus Service' section in service file '/usr/share/dbus-1/services/org.x.StatusNotifierWatcher.service' 

When I try to open Konsole I get

 user@1000.service app-org.kde.konsole@66fa5195d88f46d0ac301c2664b375f8.service: Main process exited, code=exited, status=127/n/a 

more general QT6 errors

 user@1000.service kf.config.kconf_update: /usr/share/kconf_update/konsole.upd defined Version=5 but Version=6 was expected 

 user@1000.service couldn't load "/usr/lib/qt6/plugins/discover-notifier/DiscoverPackageKitNotifier.so" because "Cannot load library /usr/lib/qt6/plugins/discover-notifier/DiscoverPackageKitNotifier.so: libpackagekitqt6.so.1: cannot open shared object file: No such file or directory" 

when i try to open Dolphin

 user@1000.service app-org.kde.dolphin@2828bc9e9cb6420db02199a1ab444f83.service: Main process exited, code=exited, status=127/n/a

user@1000.service app-org.kde.dolphin@2828bc9e9cb6420db02199a1ab444f83.service: Failed with result 'exit-code'. 

 locale 

Shows everything has en_us_8UTF set but LC_ALL is empty.

I also uncommitted en_gb-UTF8 in my locale.conf - as I live in the UK.

Running

 paccheck --quiet --md5sum 

gives me a smallish list of packages (loads of qt6 packages, kwin, layer-shell-qt, libjuice, libnm, xapp, shiboken6 etc etc all with warnings "mtree data not available (invalid argument).

running

 pacman -S kwin 

(for example) results in "errors occurred" and "no packages were upgraded"

Any ideas as how best to proceed?

Thanks

Re: [SOLVED] Pacman -Syu Crashed - Got Issues

What's  the exact output from the "errors occured" pacman run?

Generally speaking  you've done some good analysis, you'll have to reinstall all the packages with broken mtrees and empty libraries (mtrees means the pacman DB got corrupted, reinstall the affected packages with --dbonly following an actual reinstall, so picking your example

pacman -S --dbonly kwin
pacman -S kwin

and you'd best do that for the entire list you got from paccheck with regards to mtree errors.

That should be able to get you back to speed in this regard...

As for why you crashed during the update. Sadly there seems to be an interaction bug between the nvidia 550 series of drivers and systemd when systemd gets updated which can lead to corrupted kernel memory and thus a full on kernel panic. If your GPU is Turing+ you could try to go with nvidia-open which shouldn't be affected or going to the 535 line of drivers on the AUR: https://aur.archlinux.org/packages/nvidia-535xx-dkms (note for a DKMS kernel module to work you need to have linux-headers installed) see https://bbs.archlinux.org/viewtopic.php?id=293400 for more information when this first surfaced.

Hello, Thanks.

Okay so slowly moving through the list and re checking each time with

 paccheck --quiet --md5sum 

that that package was fixed - worked!

After all packages were fixed I rebooted to a fully working system.

As for the NVIDIA interaction bug the only time this has happened was on this system upgrade, otherwise my terminal has never crashed. Yesterdays was the only 'issue' Ive had so far.
Thanks once again!

Re: [SOLVED] Pacman -Syu Crashed - Got Issues

Well you should generally be weary of this, and  a crash during an update with more vital components, e.g. pacman or dependencies of it (or your shell) could leave you with an unbootable or otherwise annoying to repair (without a live disk) system. Hopefully these bugs are getting fixed, but from what I've heard they're still not quite there yet, AFAIK 560 should be the next stable series, hopefully these issues can get ironed out on the nvidia side.

In any case, if you consider this [SOLVED] please mark it as such by editing the title in your initial post.

Re: [SOLVED] Pacman -Syu Crashed - Got Issues

I hear you, thanks once again.
I keep a live USB to hand but do feel I have gotten lucky with this crash as you rightly say it could have been a lot worse.

I'll look into the open drivers.
