[SOLVED] vmlinuz-linux not found

tigerjack · 2024-05-24 11:48:19

My device got frozen during a pacman update, and I had no choice but to forcefully shut it down.
At the reboot,

error: /boot/vmlinuz-linux not found

So I restarted using a USB stick and did the following

mount /dev/<Root> /mnt
mount /dev/<boot> /mnt/boot
arch-chroot /mnt

However, last command resulted in an error message

/bin/bash: error while loading shared libraries: /usr/lib/libncurses.so.6: file too short

So I need help in proceeding from here.
I tried to upgrade the system, but it rightfully complains that I do not have enough memory available.

https://wiki.archlinux.org/title/Pacman … an_upgrade
--root … --cachedir

First check

sudo LC_ALL=C pacman -Qkk | grep -v ', 0 altered files'

Every package that shows up w/ a broken or missing mtree needs to be first installed w/ the "--dbonly" flag or you'll get file conflicts.
Avoid using --overwrite

Hello Seth, thanks for the help. I didn't know about those flags.

I tried a slightly modified version of your command

LC_ALL=C pacman --root /mnt --cachedir /mnt/var/cache/pacman/pkg/ -Qkk 2>&1 | grep -v ', 0 altered files'

But it was still too verbose, signalling tons of MD5 checksum mismatches.

I tried with grep 'mtree', but I don't know if this is the kind of filter that I need.

seth · 2024-05-24 17:15:19

Yeah, sorry - that command is a textblock

If you think it's really A LOT of affected packages, re-install all packages - first pass w/ "--dbonly" the second pass w/o.
The first pass might get you some errors from ld (empty objects etc.) and other failing alpm hooks - ignore those and move on.
The first pass only serves to fix the database, not the files themselves, so there'll be broken file and they might trigger errors.

What about running it only on the files shown with an -Syu?
Or even just run pacman -Syu --dbonly?

Btw, I tried it with a few files, and it appears that I have corrupted PGP signatures

seth · 2024-05-24 17:42:14

That's not gonna cut it because you'll have up-to-date versions of most packages. They're just corrupt.

Please don't paraphrase, https://bbs.archlinux.org/viewtopic.php?id=57855
The details of the error matter a lot.

maybe let's have a look at the situation:

LC_ALL=C pacman --root /mnt --cachedir /mnt/var/cache/pacman/pkg/ -Qkk 2>&1 | grep -v ', 0 altered files' > /tmp/howbadisit.txt
cat /tmp/howbadisit.txt | curl -F 'file=@-' 0x0.st

That invert match for grep is providing lot of output corresponding to MD5 checksum/SHA256/UID/GID/Modification time mismatch (lot like in it's running for minutes and still didn't stop).
Do you think there is another way to check for the corrupted packages?

seth · 2024-05-24 21:49:24

it's running for minutes and still didn't stop

=> Re-install all packages.

I didn't think it would come to that
Anyway, I tried the following

LC_ALL=C pacman --root=/mnt --cachedir=/mnt/var/cache/pacman/pkg -Qnq | pacman --root=/mnt --cachedir=/mnt/var/cache/pacman/pkg -S --dbonly -

and I am back to the corrupted packages problem

corrupted (invalid or corrupted package (PGP signature))

for most packages.
All of them are highlighted here
https://0x0.st/XZyF.txt

seth · 2024-05-25 06:43:52

You don't *have* to re-install *all* packages, but the broken ones.
It's just that if (almost) all packages are broken, it's kind easier to re-intall them all than trying to filter the 3 unaffected.

And when I tried to reset the keyring

root@archiso ~ # pacman-key --populate
==> ERROR: There is no secret key available to sign with.

Probably it would be easier to get the keyring directly from /mnt instead of the archiso, but I still cannot chroot inside it.

I tried also with a populate without a refresh of the keys, but with no luck.Should I just delete the pacman cache directory? I am afraid I don't have enough space on the device to just backup the cache directory (it's 14GiB).

While refreshing the keys, I got quite a of output. tmux history shows only the latest strings https://0x0.st/XZvu.txt

EDIT: even a fresh cache results in the same output, that is, a bunch of lines saying

<package> is corrupted (invalid or corrupted package (PGP signature)).

seth · 2024-05-25 09:28:08

You're using Pacman and Keys from the ISO (this ist also why updating/resetting the Keys of the installed system doesn't Help) and those are too old or at least have too many expired ones in the WOT

Not If you apply that to Pacman itself as well - feelbfree to try whether that works now.

That's exactly what I did in the previous post, but apparently it didn't work, and I was just curious way

Anyway. I updated my archiso to the latest version, and the first thing I noticed is that arch--chroot still produces the same error message. Is this bug of some sort?

Then I updated again the pacman keys, and used the gpgdir option. The PGP problem is not there anymore, but now I have a bunch of Errors saying that the file exists in filesystem.

PGP was probably No Problem with the new ISO at all.
You'll now have to Reinstall the packages with the --dbonly flag First and then without it.

Ok, now after a lot of trials, pacman completes without errors. Thanks!

However, the original problem is still not solved. At reboot, the vmlinuz-linux file is still not found.

You forgot to mount the boot Partition into /mnt/boot ?
Do so and re-install the kernel. You should also be able to chroot again?

I could swear that the partition was there, but apparently it wasn't. Now everything seems to work like a charm!

I'll leave here all the steps for future references. Thanks Seth for your infinite knowledge and help
