If you can wait, then let 2.2.8 get released if the developers say that mysql-5 will work. That will be the easiest way forward. I used apt-pinning to get Koha 2.2.7 working under Etch with mysql-server-4.1. Koha has worked well for me so far. The big problem with this approach is that it'd be difficult to install packages like kbarcode which depend on the more recent mysql and a host of kde dependencies. But if you're impatient the following might be of some help. Proceed at your own risk. Here's the contents of my /etc/apt/preferences file: Package: mysql-server-4.1 Pin: version 4.1.11a-4sarge7 Pin-Priority: 1001 Package: mysql-client-4.1 Pin: version 4.1.11a-4sarge7 Pin-Priority: 1001 Package: libdbd-mysql-perl Pin: version 2.9006-1 Pin-Priority: 1001 I added sarge repositories, updated and then: #apt-get -t stable install mysql-server-4.1 This should install mysql-server-4.1 and dependencies from stable in as far as it is possible before using another repository to resolve dependencies. Then I commented out the stable repository and updated again. Whatever you choose: good luck. --Jason
