[Koha] Software error in koha

[Mark Tompsett]

Greetings,

Your error suggests to me that you installed from a tarball under Ubuntu. 
This is not the recommended way to install Koha under Debian-based operating 
systems. You may have misread the questions when doing the make (swapped 
user and password?), or made a typo when entering the password. The next 
problem is, after installing Koha, you need to go to the staff client first, 
not the OPAC. Hope you are able to track down at which step you made your 
mistake in the installation.

GPML,
Mark Tompsett
