A recent update to the phoc package in Alpine aports may result in an error
when installing the upgrade:
...
(15/16) Upgrading phoc (0.13.0-r0 -> 0.13.0-r1)
ERROR: phoc-0.13.0-r1: trying to overwrite usr/lib/libwlroots.so.9 owned by wlroots-phosh-0.14.1-r0.
(16/16) Purging wlroots-phosh (0.14.1-r0)
If you encounter this, it can be resolved by simply running:
$ sudo apk fix
The phoc package will be fixed in aports soon.
