There was a minor display issue in SpiderOak One and Groups for 7.3.0 on Linux. When run from the command line (not GUI), you will see the diagnostic message "SSL: TLS v1.2 not available, using default" along with whatever output is normally expected for the command being run. This is an internal diagnostic message that was useful to us during pre-release testing but should have been removed before public release. This was fixed in a subsequent release, so you should upgrade to the current version of SpiderOak One or Groups. In the meantime this is merely a display issue and all command line options run fine.
