Hello, thanks to Ionic we found the problem - ubuntu and debian jessie moved the scdaemon-binary from /usr/bin/scdaemon to /usr/lib/gnupg2/scdaemon and because that path is not in the PATH of the user x2goclient was unable to run the scdaemon at startup. Adding the path to PATH or symlinking the binary to a PATH folder will result in the expected behaviour Kind regards Florian Wicke Hetzner Online AG Industriestr. 25 91710 Gunzenhausen / Germany Tel: +49 9831 505-187 Fax: +49 9831 505-387 florian.wicke@hetzner.de www.hetzner.com Register Court: Registergericht Ansbach, HRB 3204 Management Board: Dipl.
