[Bug] error: Bus owner changed, aborting. This likely means the daemon crashed

[boooooooaq]

Describe the bug

When running rpm-ostree upgrade / install / uninstall / update I get almost every time:
error: Bus owner changed, aborting. This likely means the daemon crashed; check logs with journalctl -xe.

Full journalctl -xe output:

Reproduction steps

What I did to reproduce this in a Boxes vm is the following:
Note: I only succeeded to reproduce it ones.

1. install all my layered pkg's: rpm-ostree install btop distrobox gparted guestfs-tools libvirt-daemon-config-network libvirt-daemon-kvm openrgb python3-libguestfs qemu-kvm steam-devices timeshift virt-install virt-manager virt-top virt-viewer zsh
2. Follow This guide for PCI-Passthrough, in my case what I did in the vm:
   2.1 sudo rpm-ostree kargs \ --append-if-missing="intel_iommu=on" \ --append-if-missing="iommu=pt" \ --append-if-missing="rd.driver.pre=vfio_pci" \ --reboot
   2.2 sudo rpm-ostree initramfs \ --enable \ --arg="--add-drivers" \ --arg="vfio-pci" \ --reboot

after the last step I get the error: Bus owner changed, aborting. This likely means the daemon crashed; check logs with journalctl -xe.

Expected behavior

rpm-ostree upgrade / installs / uninstalls successfully

Actual behavior

It usually go's as follows:

Additional information

I still sometimes succeed to upgrade my system after enough reboots I would estimate my success rate on my actual system to be ~1/50.

Also I use ext4 instead of btrs if that's of any important's in this case.

Maybe related to #4966 ?

Any help would be appreciated!

If anyone has a similar issue to what I have, I made a simple bash script to workaround it, here it is for would it be of use to anyone else (it basically loops given command until it exits successfully):

#!/bin/bash

red_prefix="\033[31m"
red_suffix="\033[00m"

green_prefix="\033[32m"
green_suffix="\033[00m"

read -p "What command do you want loop? (Default: rpm-ostree upgrade): " user_response

if [ -z "$user_response" ]; then
   user_response="rpm-ostree upgrade"
fi

command=$user_response

until $command; do
 echo -e "$red_prefix"Command failed. Retrying..."$red_suffix"
 sleep 1  # Optional: add a delay before retrying
done

echo -e "$green_prefix"Command succeeded."$green_suffix"

Yes, this looks like the same issue as #4966. Let's track that one instead.
