installed StarDog from .zip per windows installation instructions.
setx STARDOG_HOME "%USERPROFILE%\stardog-home"
typing in Windows Cmd:
stardog-admin start server
the following error occurs:
com.google.common.util.concurrent.UncheckedExecutionException: java.lang.IllegalStateException: Unable to load cache item
java version "19.0.1" 2022-10-18
Java(TM) SE Runtime Environment (build 19.0.1+10-21)
Java HotSpot(TM) 64-Bit Server VM (build 19.0.1+10-21, mixed mode, sharing)
Any ideas welcome.
I believe it may be because of the java version. The officially supported version are 8 and 11
Okay switching to Ubuntu 20.04 LTS and installing StarDog as per instructions, The StarDog Service does not start with the following error:

Can you take a look in
/var/opt/stardog. This is the location of
$STARDOG_HOME by default. There should be a
stardog.log in there. Is it possible you do not have a license located in your
"A valid Stardog license was not found in /var/opt/stardog. Please copy your license file to this location or visit https://stardog.com to acquire a new license."
hmmm how does one obtain the license to run the StarDog Free Version on Ubuntu? Didn't see instructions for that for Ubuntu install.. kinda assumed it came in the install, but obviously not.
If you fill out the form here on our website: Download free with Stardog - Download Free Page | Stardog you should be emailed a license key with some restrictions. Once you have that, place it in
$STARDOG_HOME and attempt to restart the service.
@noahgorstein Thanks! After obtaining the license and resolving permissions issues with placing the file to $STARDOG_HOME... Server is up and running and IDE connected!
