Hi, today i needed install Firebird 2.1 in my machine.
First, i trying installing using Synaptic, but not work.
Now, you can install using this commands:
Classic Server:
sudo apt-get install firebird2.1-classic
Super Server:
sudo apt-get install firebird2.1-super
After install, you need configure SYSDBA password:
Classic Server:
sudo dpkg-reconfigure firebird2.1-classic
Super Server:
sudo dpkg-reconfigure firebird2.1-super
See you later.
