So basically you don't trust this project enough to run an "USB stick" creator binary that is restricted/limited by the user rights of your account but you want to run the distribution on a dedicated system were it has full control over your hardware?
Seriously? Take a step back and re-read what you just said.
You don't need to use the installer if you don't want to. Just download the gzip-ed image from the downloads section and then, as root, write it directly to your USB pendrive, SD card etc - but beware, don't choose the wrong device our you might nuke your harddrive
Doh! There is a direct download section further down the page... all I need is the LibreELEC-Generic.x86_64-8.2.5.img.gz!
Thanks!
From downloads – LibreELEC choose the Linux installer, that downloads a bin file, so you can create a Libreelec installer flash drive from Linux.
I know, the problem is that I don't want to run that bin file... at least not on my pc. That's why I mentioned vm's 
It still seems a bit silly to me that an installer is needed to create an installer on a flash drive. Just provide an image and I will write it to a flash drive myself.
Anyway, thanks for the help.
I'm curious, why don't you want to run a file?
I am used to arch/debian, and don't trust much outside such well known repo's.
But I guess I can create a vm and run the installer from inside there.
There is no other way, I have to run a file? That is just not going to happen. Why not provide an image to write to a flash drive?
I guess libreelec is not for me. Thanks for the help anyway.
I want to install libreelec on a pc, and it seems I have to download a bin file and run it? Is there an iso somewhere i can use with dd to write to an usb stick? Running a bin file seems a bit not safe...
