Q: I get one of the following errors when I try to use any of the ssh-based plugins:

• ERROR - Couldn't run job because: Private key file is encrypted
• ERROR - Couldn't run job because: Permission denied (publickey,hostbased).

A: You need to set-up password-less ssh-keychain access to the remote hosts you want to use. How this works is explained in SSH and GSISSH.

Q: I get the following error message if I try to install Bliss via pip or easy_install:

src/MD2.c:31:20: fatal error: Python.h: No such file or directory
compilation terminated.

A: SAGA Python uses Paramiko, which in turn uses PyCrypto, a set of cryptographic modules for Python. Unfortunately, PyCrypto requires compilation against certain system libraries during installation. For this, you need to have the Python header files installed. Many systems have those installed by default. If not, a simple apt-get install python-dev usually does the trick.
