February 6th 2019 we get an update in that breaks our installation.
I had seen what packages were installed and I did notice lightdm in there.
LIGHTDM is one of your major packages – it starts out display or login manager. Other important packages to keep track off is linux and systemd.
IF you did not see the packages that came in you can use our alias RIP in the terminal to see the last packages.
You computer will function fine until you reboot and then lightdm throws you lots of errors.
We have made already a video about the power of TTY here but it can not hurt to make one specifically for this issue.
Get to a TTY with CTRL + ALT + F2 or F3 or … (Virtualbox users use RIGHT CTRL + F2
Choose the prior version with a number
Add lightdm to IgnorePkdg : Y
reboot and have fun again
Other Arch Linux users need to install downgrade with an AUR helper like yay or trizen.
A few hours later the fix comes in
A few hours later lightdm is fixed
Bug report is here : https://bugs.archlinux.org/task/61654?project=1&string=lightdm
