How to install Cyanogenmod / LineageOS 13 (Android 6.0.1 Marshmallow) with GApps and Signal Messenger onto a Samsung Galaxy Ace 2 GT-I8160?

This question is uncommon and may not apply to a lot of you. But I dropped two phones in a row so I needed to grab my old Samsung Galaxy Ace 2 GT-I8160 backup phone and revive it. I had it already running with a previous version of Cyanogenmod 11 (Android 4 Ice Cream Sandwich) and already saw that I could possibly run it with Anroid 4.4.4 and a custom Kernel from XDA Developers Forum (last updated Jan 30th 2023). Although that might be sufficient for others, it turned out that the messenger application I'm using is Signal for Android, which has a minimum OS requirement of Android 5.0 . Later I discovered a more recent version of Cyanogenmod / LineageOS 13 (Android 6.0.1 Marshmallow) on XDA Developers Forum , which was referring a packed Version of SergeyL on the 4PDA forum . I downloaded lineage13.0-20180914-UNOFFICIAL-codina_SergeyL.zip from the given link in the 4PDA forum and made sure it fits the given md5sum

. To download Signal from the Google Play Store I opted for Open GApps ARM 32bit for Android 6.0 and the Pico variant (Ace 2 has a ARM Cortex A9, ARM v7 32bit CPU ). I downloaded open_gapps-arm-6.0-pico-20220215.zip from the Open GApps website. Because I was certain that I can install both packages, I put them onto a Micro SD card, plugged it into the phone and booted into CWM (ClockWorkMod). Installing Cyanogenmod / LineageOS 13 went pretty well. So I rebooted and recognized, that CWM had been replaced by TWRP 3.0.2-0 (Team Win Recovery Project). When I tried to install GApps i got an *Error Code: 70*. It told me: *Insufficient storage space available in System partition. You may want to use a smaller Open GApps package or consider removing some apps using gapps-config.* To keep it short, the proposed solution of using a

-config

file wouldn't work. Wiping System, Data, Cache from TWRP and installing everything again gave the same result. So the question is: ***How to install Cyanogenmod / LineageOS 13 (Android 6.0.1 Marshmallow) with GApps and Signal Messenger onto a Samsung Galaxy Ace 2 GT-I8160?***
