I'm building for sailfish 7.1.2_r29 and trying to work with the new AB
update system. I'm unable to use android.os.UpdateEngine to apply a new
update.
It immediately fails with a few errors,
11-14 01:00:51.298 658-658/? E/update_engine:
[1114/010051:ERROR:utils.cc(199)] 0 == writer.Open(path, O_WRONLY | O_CREAT
| O_TRUNC, 0600) failed: No such file or directory

/data/ota_package/update.zip
I double checked the sepolicy's in system/sepolicy and they are being
included inside the build correctly, but still for some reason I'm unable
to apply an update with the new update system.
Sorry, my understanding of SEPolicy is very very limited, so I am not sure
what exactly is happening.
Anywhere I should look or anything I can try would be much appreciated.
Thanks in advance
