When you are trying to get Vivado Remote Connections working on Ubuntu, you might have an issue to establish the connection.
This can be easily solved by adding a symlink to your bash, called sh. You can do this for example using the following commands:

```bash
$ mkdir -p ~/.local/bin
$ ln -s /bin/bash ~/.local/bin/sh
```

Thanks to ole2 for providing this solution in the xilinx forum, which you can find here:

As he points out, this seem to be a bug in Vivado. Vivado seems to call a script with #!/bin/sh and expects a bash to be executed. But for Ubuntu, /bin/sh points to /bin/dash per default. An alternative solution is to re-configure this link using:
```bash
$ sudo dpkg-reconfigure dash 
```

I had this issue in Vivado 2016.4 and Ubuntu 16.04 LTS.
