[SOLVED]NetworkManager wifi not working due to dbus issues

While I was updating my system today, my laptop went into a kernel panic(screen freeze, caps lock LED blinking, sound being replayed, etc) so I manually shut my laptop down by pressing the power button.

When I tried booting in from grub, however, grub goes into grub rescue mode as it couldn't find the kernel image. I then used a live cd to chroot, mount the proper partitions and reinstall the kernel, systemd and mkinitcpio which solved the grub issue. Yet during the boot, the kernel messages show the D-Bus System Message Bus alongside Network Manager, Bluetooth, etc failed to start like in this post: https://bbs.archlinux.org/viewtopic.php?id=292174

I then got my GUI and other services to load again by replacing dbus-broker-units to dbus-daemon-units via a chroot but now the wifi no longer works. The Network Manager logs showed that wpa_supplicant failed to start:

May 05 23:08:50 archlinux NetworkManager[705]: <error> [1714925330.0592] device (wlan0): Couldn't initialize supplicant interface: Failed to D-Bus activate wpa_supplicant service

And checking the wpa_supplicant logs showed this:

-- Boot 95161a5d85b3490d91a709d4cb09c08b --
May 05 23:08:47 archlinux systemd[1]: Starting WPA supplicant...

May 05 23:08:47 archlinux systemd[1]: Failed to start WPA supplicant.

Could anyone offer me some insight?

Re: [SOLVED]NetworkManager wifi not working due to dbus issues

Can you reinstall the pcsclite package to fix the shared library error? Also reinstall anything that was due for the interrupted system upgrade.

EDIT: the 'grub-rescue>' prompt indicates that GRUB cannot find it's modules.

Re: [SOLVED]NetworkManager wifi not working due to dbus issues

I got it fixed now! I renamed all those files in the error messages:
https://wiki.archlinux.org/title/Pacman … )%22_error
And then reinstalled pcsclite. I booted in again and the wifi works now. Thank you for the guidance!
