MinMicroG-Backend-2.7-beta2 on lineage-17.1-20200312-mako install issues

Previously running last official lineage 15.1, then bumped to unofficial 16.0 with manual priv-app install of NetworkLocation.apk (no GAPPS) and the /etc/permissions workaround. With the latter, all the location status was "green" and working with only the dejavu backend (tested using openweathermap app location status). Note these both included the lineage addonsu binary, however, with 16.1 on hammerhead (and root for apps disabled) location setup/function is still green.

Since 17.1 has no su binary I only have adb root access but the above "remount system to install location" trick is broken, so I followed the wiki page (on reddit) and did the fresh 17.1 flash on mako followed by the backend flash and after setup I ended up with the unchecked box error on the issues page "UnifiedNlP do not have Location to test Geocoder (not ticked)"

I downloaded the permissions file and ran the command via (root) adb shell:

eval "$(cat "/sdcard/Download/nanodroid-perm.txt")"

which gave 2 permission errors and the box is still not checked, after a couple of reboots and making sure microg has all the location perms, etc. That said, the weather widget still works! Go figure...

Permssion errors:

Start by reproducing the reported setup on lineage-17.1-20200312-mako with MinMicroG-Backend-2.7-beta2, then review the nanodroid-perm.txt command output and the two failed permission grants. Done means the UnifiedNlp location and geocoder checks pass without permission errors while location functionality remains working.
