RAR files are no longer supported in these test builds as RAR support is now provided by an add-on that doesn't currently build - once the add-on API changes are complete the add-on may be added to the LE 9.0 Repository. Until then, if you want RAR support stick to an official Kodi 17 release (ie LibreELEC 8.0.2).
