On the main site the developers asked for people to report issues. I download LibreELEC (Leia) v8.90.005 ALPHA – LibreELEC ( libreelec-generic.x86_64-8.90.005.img.gz ), create a new installation image and installed it fresh on a empty drive.
First thing (because i mainly use libreelec as TV media center) i installed TV-Headend backend - that seems to have worked.
Then i liked to install the fronted so that i can use it. I got the error "ERROR: CAddonInstallJob[pvr.hts]: The dependency on kodi.binary.instance.pvr version 5.10.2 could not be satisfied."
An other gui-error was, that the text above reporting the error stopped sliding the text with the error message. With other words: I was not able to read the error in kodi itself.
At that point the main usage for libreelec is not available for me. Please fix this so that i can continue testing.
