Recently something happened to my OMV installation where all the OMV executables disappeared from my OS. I successfully reinstalled it (now running 5.5.5-1), and am now able to log into the web console. But whenever I click on the OMV-Extras tab, I get the error "RPC service 'OmvExtras' not found." I tried reinstallating OMV-Extras using the command line instructions here, but it didn't solve the problem. I then tried downloading the .deb file and using the OMV plugins upload button, and that failed with a long error message (below). Thoughts?
