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”
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.
All good, but still not able to use kernel 5.8 in combination with VirtualBox, and i still can’t find the actual issue. The VM starts and the entire system hangs unrecoverable. Switched to 5.4 because with 5.7 i get a lot of codedumps when using Krita.
First gen i7 CPU and Nvidia GPU here … that might add some spice to the issue, but in my case the real issues is related to the linux58-virtualbox-host-modules
This update literally removed ALL of my installed applications.
It started with a conflict between nvidia-390xx-utils and nvidia-450xx-utils.
As I only own an old GeForce 550 Ti, I have to stick with the 390 driver version, though.
Unfortunately, the only way to resolve this conflict was removing mhwd-nvidia-450xx. This, unfortunately, also removed my nvidia-390 driver as well, so I had to re-install it after the update.
Because there also was a new kernel version, I then rebooted.
After reboot, I got “Failed to start Light Display Manager” and no graphical desktop.
So I re-installed both xfce and LightDM, but then it complained about lightdm-slick-greeter missing as well. So I had to install that also.
After all that, I could get back to the desktop. Unfortunately, it turned out that ALL of my installed programs (Libre Office, Evolution, Double Commander and so on) were gone.
Now I am in the process of re-installing everything step-by-step. Fortunately, my user settings seem to have been preserved so for example, I have all my mailboxes back in Evolution without the need to re-configure.
Such a behavior on an update reminds me a bit of the Windows 10 horror stories. So please let me kindly ask you to abstain from reproducing such things on Linux even though Microsoft is the market leader and thus, must have done something right
Those craving for VirtualBox, consider trying qtemu-git (AUR) for a proper virtualization alternative without procrapietary VB modules
Nice Qt interface, looks fine in Plasma DE:
Wrt VBox and Linux 5.8, I dare to „add up 1+1“ and speculate. The problems of VB 6.1.12 with Kernel 5.8 AFAIK are down to the Linux developers’ quest for security (allocating memory to executable code). So I really hope that Manjaro patches to the kernel (cf. above, someone mentioned @philm patches) if there is s.th. in that direction will be removed when VB 6.1.14 arrives and works. Pls forgive me if I‘m wrong!
