dunst: /usr/bin/dunstify exists in filesystem (owned by dunstify)

dunstify has been depreciated for dunst. Uninstall dunstify before updating or update by:

sudo pacman -Syyu --overwrite /usr/bin/dunstify

PAM and PAMBASE got updated, which might prevent you from login

Due to updates from pambase and pam you might take care about any .pacnew files in /etc/pam.d as for example pam_tally, pam_tally2 and pam_cracklib got deprecated. Read in the ArchWiki about managing those files.

Typical issue:

For recovery, it is enough to boot with kernel option “systemd.unit=rescue.target”, then proceed into /etc/pam.d and merge “system-auth” and “system-auth.pacnew”

If you have however issues with pam or/and pambase please open a new thread in our dedicated support section.

Older Issues

System takes a long time to boot

If you’ve got errors like Failed to start Network Manager Wait Online. you can try removing systemd from passwd and group in /etc/nsswitch.conf as described here
Update: If you can see the line
dbus-daemon[1453]: [system] Connection has not authenticated soon enough, closing it (auth_timeout=30000ms, elapsed: 45146ms)
in in your dbus log ( journalctl -b -u dbus ), the new/better workaround is to switch cups from service to socket as described here:
systemctl disable org.cups.cupsd.service
systemctl enable org.cups.cupsd.socket

I think I’ve some font problems

With the update of fontconfig some major rules how fonts get applied changed. Make sure that your system has ttf-dejavu installed. A more in depth explanation can be found here.

Gnome-shell-extension-pop-shell is currently incompatible with wayland

… and causes the system to freeze when the first window is tiled and can render it unbootable. Solution is a hard reset and disabling either pop shell or wayland. If the system becomes unbootable, use a live USB to edit /etc/gdm/custom.conf to disable wayland and reboot.
