nvidia-450xx-utils and nvidia-440xx-utils are in conflict

Please click the ► at the beginning of this line to view this solution

  • If you get the following error message:

    resolving dependencies...
looking for conflicting packages...
:: nvidia-450xx-utils and nvidia-440xx-utils are in conflict (nvidia-libgl). Remove nvidia-440xx-utils? [y/N] y
error: failed to prepare transaction (could not satisfy dependencies)
:: unable to satisfy dependency 'nvidia-440xx-utils=440.100' required by linux54-nvidia-440xx
:: removing nvidia-440xx-utils breaks dependency 'nvidia-440xx-utils=440.100' required by linux58-nvidia-440xx

Warning: do not reboot until this procedure tells you to starting from the next step!

  • Please note the exact nVidia driver you have running by executing:

    mhwd --listinstalled

  • Please note the kernel(s) you’ve got installed and remove anything 440-related, including CUDA by executing:

    pamac remove nvidia-440xx-utils linuxZZ-nvidia-440xx cuda nvtop

    where ZZ is/are the kernel version(s) you’re running.

  • Repeat for all the kernel versions you have

    How do I know which kernel versions I have?
    • execute ls /boot/linux*
    • any nulber after linux before the - (minus sign) are the kernel(s) you have installed

  • If you would have any other old nVidia drivers that you don’t need any more because your card is supported by the 450 series get rid of them as well.

  • now install the same family of 450 driver you had for the 440 driver, by executing:

    mhwd --install pci Your450Family

    where Your450Family is obviously one of video-hybrid-amd-nvidia-440xx-prime OR video-nvidia-440xx that you noted above

  • And finally:

    sudo reboot

If this would not have solved your issue, please open a new issue here and state that you followed this procedure already.

Warning: directory permissions differ on /var/lib/dhcpcd/

followed by:

filesystem: 700 package: 755

Please click the ► at the beginning of this line to view this solution

  • The solution:

    sudo chmod 755 /var/lib/dhcpcd/

  • The explanation:
    The DHCP Daemon expects the security permissions to be 755 but your system is set to 700. This is just a warning (today) but to ensure you remain up-to-date with the latest and greatest security rules it’s advised to execute the above command.

virtualbox NS_ERROR_FAILURE (0x80004005)

Please click the ► at the beginning of this line to view this solution
  • The solution:

  1. You need to add your user back into the virtualbox user group

    sudo usermod --append --groups vboxusers $USER

    (Change $USER to the correct user name if not for yourself)

  2. Upgrade the VirtualBox extension pack to the latest version by executing:

    pamac build virtualbox-ext-oracle-manjaro

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

Please click the ► at the beginning of this line to view more detailed information

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”

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.
