This issue was reported in several places, so for example in the current thread and also here macOS High Sierra media installer. When I tried to create a bootable installer for High Sierra I came across the problem that the installer downloaded from the App Store proved to be a "stub" version. Then, copy the download directory off to another machine for future use.
#WGET MAC OS X HIGH SIERRA INSTALL#

When the download is complete, the installer will prompt for a system restart. After that, it will begin downloading to "/macOS Install Data" on the local machine. Click "Continue", accept the licensing agreement, select the install drive, then the installer will prompt for an admin password. It will launch "Install macOS High Sierra" after the download completes.
From the App Store, grab the High Sierra installer.
