Nightly update issue on Generic/Legacy – only one update visible after switching to test channel?

Hello everyone,

I installed LibreELEC Generic Stable 12.0.2 on an SSD alongside Google TV (installed via a YouTube tutorial).

I now want to install LibreELEC Generic Legacy Nightly as a third operating system on the same SSD, ideally by extracting the ISO file to its own partition (as recommended for Google TV). The goal is to run a second Kodi profile, as I've had issues using multiple profiles with different skins/add-ons in a single LibreELEC installation.

My hardware:

▶️HP EliteDesk 800 G1 TWR Tower-PC

▶️Display via DisplayPort to HDMI adapter

▶️Intel Core i7 (4th Gen)

▶️Integrated Intel GPU

▶️20 GB RAM

▶️SSD 1: Windows 11 24H2

▶️SSD 2: LibreELEC + Google TV

The issue:

I tested LibreELEC Generic and Generic Legacy Nightly on MicroSD (Run and installed mode) and also by cloning the install to SSD.

Each time, I was only able to install one Nightly update after switching to the test feed (https://test.libreelec.tv/).

After the update, the sub-version list disappears – I can still see the main version (e.g. 13.0), but no further builds are shown.

I also tested Nightly without first installing Stable, and in those cases, no sub-versions were shown at all, even immediately after switching to the test link.

This makes me wonder: Is the test URL even needed when Nightly is already preinstalled?

Oddly, Stable shows all available builds correctly – including both main and sub-versions.

What worked before:

Before I switched to this SSD setup (which I've been using for about two years), LibreELEC Generic 11 was running from a microSD card in run mode.

There, I switched to Nightly via the test URL and was always able to install updates without any problems, including version 13.

Unfortunately, I had to overwrite this microSD card because I didn't have another one available.

Does anyone know this issue with nightly builds, where no more updates appear after the first one?

Would a debug log be helpful in this case?

Thanks in advance!

I think the linked problem is the same but the only way for me to install 2 LE on an SSD was to clone it from the Micro SD, where not everything was always copied from the storage partition and in one of my tests the 2nd LE installation even wouldn't start. However, I would find it better if I create 2 empty partitions and copiedthe required files from the ISO into them, or is cloning the MicroSD installation the only option?

Assuming you mean the .img file (not .iso) then you are thinking in the right direction. No need to clone anything.

I have now cloned sector by sector from the MicroSD to the SSD with Aomei Partition Assistant LE and the only thing I noticed when booting was that, compared to the MicroSD, the Kodi welcome screen was not displayed and if something is missing, it will surely be reinstalled with the next update (which comes out almost every 2 days anyway).

It also ensures you don't need to fix the incorrect partition/filesystem geometry data that you cloned.

But I didn't mean that I have to fix the clone errors, I meant that they will be fixed with the next update. I also looked at the boot partition of the first LE installation on the SSD again, and when I open the downloaded .img.gz file in 7zip, the same files are in there. That would mean that I only have to copy these to a new boot partition and the storage ones to a new storage partition?

The complicated bit is A and we don't support multi-boot setups because it's a pain in the rear to figure out what's needed and then support

There's already been a tutorial on the forum for dual boot using grub2win, which I used for the first LE installation. I'm sure I can use it for the second installation as well. All I need to do is copy everything in the .img.gz file using 7zip to boot to a fat16 partition and create an empty ext4 storage partition. That's it. Or do I also need to edit a file so that LE starts directly?
