[Koha] Vendor Module Error

[Joseph Chacha]

Dear Members,

I am trying to implement Koha 3.18.08.000 and I have made a succeful
installation on Ubuntu 14.04 LTS

Everything looks good so far apart from an error generated when I am
attempting to add a vendor "Software error: bad template path at
/usr/share/koha/lib/C4/Auth.pm line 161."

Any advise on how to address this will be highly appreciated.

J Chacha.
