I'd like to run Garbage Collection as the document, But could not find Advanced in Admin module. Although Artifactory Comparison Matrix said that OSS edition still support Maintenance. Is there something I could do to enable this function? I'm using Artifactory version 6.20 Thanks.
The Maintenance option does exist in the Artifactory 6.x admin UI
The only option I can think of is that you are not logged in as an admin user
