The xwayland package in Alpine Linux does not properly replace the xorg-server-xwayland package as intended, this results in the following error when performing apk upgrade:
(1/1) Installing xwayland (21.1.0-r0)
ERROR: xwayland-21.1.0-r0: trying to overwrite usr/bin/Xwayland owned by xorg-server-xwayland-1.20.10-r3.
This will be resolved in the following Alpine Linux merge request: aports!19562
Workarounds:
Either wait for the previously mention merge request to hit Alpine Linux, or do the following manually:
# apk del xorg-server-xwayland
# apk fix
