while installing koha-2.2.9 on ubuntu 6.06 i encountered the following...

MYSQL ROOT USER PASSWORD

 Creating the MySQL database for Koha...
  
  ERROR CREATING DATABASE
 
 Couldn't connect to the MySQL server for the reason given above. This is a
 serious problem, the database will not get installed.
 
 Press <ENTER> to continue:

i continued with with installation to the end. As a result of the above problem everything seems to work (adding members, searching and importing records from the internet using z39.50) But it doesnt add bibliographic records to the database- whenever i try to add records i get a server error.

will be grateful if somebody can sort me out.
