Installing libelf (0.185-1) breaks dependency 'libelf=0.184'

[TilliDie]

Did you un comment both lines in pacman.conf for 32bit multilib

[multilib]
Include = /etc/pacman.d/mirrorlist

Its just a thought as libelf / elfutils can use 32bit library’s
and your update in a later post does not show it enabled
