[Solved]Trying to recover after a broken update, pacman can't resol...

elfomelo · 2020-10-10 02:46:02

Hi,

I am trying to fix a broken install. I'm following https://wiki.archlinux.org/index.php/Pa … an_upgrade

However, when I try

pacman --sysroot /mnt -Syu

I get

error? failed retrieving file 'multilib.db' from <mirror> : could not resolve host

for every mirror.and a failed to synchronize all databases at the end. I tried pinging individual mirrors, and it works without issue.

I found a similar error in https://bbs.archlinux.org/viewtopic.php?id=135156, but my try to disable ipv6 didn't solve the issue. My /etc/sysctl.d/40-ipv6.conf file has

# Disable IPv6
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.enp3s0.disable_ipv6 = 1

Any clues on how to fix this issue?

Thanks!

Use chroot from live cd, after the chroot use the wifi-menu for internet connection, easiest because is a GUI.
Then do :

pacman -Syyu

That is so wrong in so many levels and totally unrelated to OPs issue...whatever that is...

OP you describe DNS issues yet you say PING works...
Is the live iso capable of pacstrap in your network?

Editing /etc/sysctl.d/40-ipv6.conf of the installed system will do nothing to the installation iso boot, pass "ipv6.disable=1" to the kernel when booting the iso.

Yes, but with an error. I booted, mounted my partition structure at /mnt and run

pacstrap /mnt base linux linux-firmware

It creates install root at /mnt and is able to sync with core, extra and community. Then it proceeds to install, but when it runs the post-transaction hooks i get

calll to execv failed (No such file or directory)
error: command failed to execute correctly

four times, for each of the four steps of the post-transaction hooks.

In the booting screen I typed e and added "ipv6.disable=1" at the end, then hit enter to boot. the problem persists.

Since you can ping the mirror, does pacman/curl work when you just hardcode the mirror IP in /etc/hosts?

I changed the first server of pacman.d/mirrorlist for

Server = 128.211.151.254/archlinux/$repo/os/$arch

. Still "failed retrieving file" errors.

seth · 2020-10-10 16:35:16

Can you
a) ping 128.211.151.254
b) curl -v 128.211.151.254 > /dev/null
?

What's "ip a; ip r" (in doubt make a photo, only post a link)

There's nothing off and you can download from the mirror.
Is the message still/now

failed retrieving file 'multilib.db' from 128.211.151.254 : could not resolve host

??
Can you

curl -o multilib.db http://128.211.151.254/archlinux/multilib/os/multilib.db

?

I can, and then I realized the "http://" was missing in the begin of the Server line. I added that and it is able to connect now!

It is a breakthrough, but I'm stumbling in another error now. After

pacman --sysroot /mnt -Syu

I get "missing required signature" and "invalid or corrupted package (PGP signature)". I believe I need to update my pgp keys, but do I need to do this in the iso or in the old system, and if the latter, how?

seth · 2020-10-10 18:01:34

Pre-install archlinux-keyring (using the sysroot switch from the iso), but there could also just e a broken package in the cache (depending on when your previous update failed)

pacman --sysroot /mnt -S archlinux-keyring

gives the following errors

GPGME error invalid crypto engine
archlinux-keyring: missing required signature
failed to commit transaction (invalid or corrupted package (PGP signature))

Should I

rm /mn/var/cache/pacman/pkg/*

?

seth · 2020-10-10 20:22:29

You should at least delete that package, but if you don't mind the traffic, just wipe the cache are re-fetch them all, yes.

elfomelo · 2020-10-10 23:16:34

I wiped the cache, tried to install archlinux-keyring, and the same three errors happen.

loqs · 2020-10-10 23:25:07

From the installation media:

pacman --root /mnt --cachedir /mnt/var/cache/pacman/pkg -S archlinux-keyring pacman gpgme gnupg glibc

If that works try again:

pacman --sysroot /mnt -Syu

It goes beyond the keyring problem. But when it goes to "Processing package changes" and "Running post-transantion hooks" it gives

call to execv failed (No such file or directory)
error: commend failed to execute correctly

repeatedly after every single step.

loqs · 2020-10-10 23:35:07

pacman --root /mnt -Qkk 2>&1 | grep -Fv '0 altered files'

Pipe the output to a pastebin, see the tip box from the link.

Do you have a backup of any data you wish to preserve?
I would suggest running a S.M.A.R.T. self test, after that has finished post the results of

# smartctl -a /dev/<device>

As the following which should be after filesystem was restored is not a good sign:

The short self test is here http://ix.io/2Alz
I would like to preserve all of it... Could you elaborate on the comment you made about previous result? What is not a good sign?

loqs · 2020-10-11 00:19:55

http://ix.io/2Alz is the same link as in post #21
The post install hooks failing, indicates to me pacman finished installing the filesystem package, however the check afterwards shows all those files that should have just been created are missing.
