[SOLVED]Post-transaction hook failures during pacstrap and arch-chroot

Hi all,

I'm running into a series of errors when using pacstrap during a fresh Arch install as per the official guide. After executing:

pacstrap -K /mnt base

I get multiple failures during the post-transaction hooks. Here's a snippet of the output:

:: Running post-transaction hooks...

pacstrap -K /mnt base 6.32s user 5.65s system 51% cpu 23.202 total

It seems like systemd-related hooks are failing due to missing or inaccessible resources in the chroot environment. I have tried solving it by updating the pacman mirrorlist

reflector --latest 5 --sort rate --save /etc/pacman.d/mirrorlist

and updating the keyring

pacman -Syy archlinux-keyring

But none of that worked. I have also serached this forum but didn't find a post about this problem.

I am able to proceed until it is time to install `networkmanager` under arch-chroot. It leads to same post-completion hook errors. Moreover,

systemctl enable NetworkManager

leads to the following red color message:

Failed to connect to system scope bus via local transport: No data available

This is my fifth time installing Arch from scratch and have never faced this issue before.

Re: [SOLVED]Post-transaction hook failures during pacstrap and arch-chroot

There's a change in systemd 258 that is causing the issues:
- https://gitlab.archlinux.org/archlinux/ … /issues/54
- https://github.com/systemd/systemd/pull/39021

Thank you very much for the prompt response!

So the course of action is to wait for the bug fix and then try again?

This should work now with the systemd 258-2 package.
