Since the update from 20th April 2018, I can't find the LineageOS update in the current path which is
/data/lineageos_updates . When I download the latest update (27th April 2018) and reboot in TWRP, there is no corresponding update file in the folder. After a reboot, the updater in the settings show me that this update isn't downloaded - altouth it did before the reboot.
Comments say that they found the update in
/LineageOS updates/ (internal storage) but on the Samsung Galaxy S4 it doesn't contain the latest update. Only a outdated version of February. No idea, how those old update got there. I didn't ever now that those folder exist. I only know
/data/linageos_updates as current update location store and
/data/data/org.lineageos.updater/app_updates for older updates before August 31st, 2017.
So in the current situation, I'm not able to update LineageOS on this Galaxy S4 directly. I want to avoid downloading the update from a PC and moving it to the device since it's not mine and the owner is a non-technical user.
