Android apps on Sailfish OS run in the android container, which has its own PID namespace. A regular app can’t signal those processes and force-killing them requires root. Crest does this by running /usr/bin/harbour-crest as root, but it doesn’t come with sudo: you have to grant it a scoped NOPASSWD rule yourself.

Steps
#

Get a root shell.

devel-su

Then, as root, install sudo:

pkcon install sudo

visudo syntax-checks the file before saving, so a typo can’t break sudo:

visudo /etc/sudoers.d/01_defaultuser

Add the line, save, then verify:

%defaultuser ALL=(ALL:ALL) NOPASSWD: /usr/bin/harbour-crest
