I think only the Server version of Harmony is supported on Linux, but the current documentation is not 100 percent clear. It seems some people installed the StandAlone version in Linux in the past, but it’s possible you would need extra work in terms of configuration. I’d suggest you contact support.
I’m not sure if this doc refers only to the server version. The Server/Database version supports Linux since I can remember, even in the time of Opus.
