A recent upgrade of postmarketos-base-ui to v2 has removed a XDG desktop file for one of Phosh's dependencies, resulting in Phosh starting up to a sad face error window with the message "Oh no! Something has gone wrong."
This can be resolved by reinstalling the package that provides the missing XDG desktop file:
$ sudo apk fix -r gnome-settings-daemon
$ sudo rc-service tinydm restart
