Installing x2go server
X2goserver-Home is a meta package which will install an x2goserver for a single host. This meta package will take care of configuring your system and you'll be able to use it after very short time. This Edition fits perfectly inside Ubuntu machines. An unlimited number of users can access this PC – but you won't be able to use multi server features like “load balancing”.
sudo apt-get install x2goserver-home
Note:- Please make sure that the following packages are installed: SSHFS, FUSE and SQLIGHT3.
