[HyperHCl]

The last lines of pacman goes like

groupadd: cannot lock /etc/group; try again later.
useradd: group 'lightdm' does not exist
passwd: user 'lightdm' does not exist

plus full log of this pid: https://pastebin.anthonos.org/view/9d4e5ff8 By the way maybe I should start an issue to request changing ‘Crashed’ message to Fatal/FF/!! level and the debug to Error/EE level…

After crashing 2 processes, pacman went on and reported a command failed to execute correctly error.

I haven't tested this. But are you serious you want to get lightdm working at this point? Anyway, an opcode not found error suggests potential bugs in the dbt code. I'll look into this issue later today.

I'm actually planning to change that opcode error lines to things like unknown opcode: %2x., (int) ins.opcode.

Per my testing this issue should be fixed now. Please test.
