I recently installed Sailfish OS via MultiRom. I got the files for it here: https://wiki.merproject.org/wiki/Ada...for_hammerhead

I cannot install any apps from the Jolla store. I hit install, it downloads, and then says it cannot install. I have scoured the internet and could not find an answer. Are those links on that wiki page outdated? Is that why this is happening? Otherwise, I cannot think of anything that would make this happen. Also want to say I already tried a Factory Reset (actually did nothing besides restart the device) and I uninstalled and reinstalled sailfish os
Thanks in advance

Well, I cannot say for sure about your case hammerhead being Nexus5, right? but at least for my Nexus7 the reason for being unable to use Jolla store is the fact that I cannot register my Jolla account for the device.

Workaround is to download the packages I need in my Jolla device and installing manually.
And of course Warehouse works OK.

The following link worked for me.
