Hi Steve,

We don't really support SL6 any more as the OS is very close to being
completely out-of-support.

Having said that, I don't see any reason why this shouldn't work (I've just
tried running it on a new CentOS6 cloud node and it appears to work)...
Could you please try running the following in the DIRAC environment and
send me the full output off-list?

env | grep PYTHON
which python
python -v -c "import six"

Do you have an alternate python interpreter or anything installed in your
python user site-packages directory in ~/.local/lib? The six package is
included in the DIRACOS bundle, so the error implies that an external
setting is preventing it from successfully finding/loading the bundled
packages.

Did you start in a completely clean shell with no other DIRAC settings
configured? If an old bashrc is already sourced at the start of the
install process it can cause weird problems like this.

Regards,
Simon
