Help with setup firebird 2.5 on linux (ubuntu)

Hello
this is my first attempt at installing firebird on a linux machine, and I preferably will go for Ubuntu (may be latest version). The problem is that I am not familiar with Linux, and thus do not know exactly how to proceed with first whether to try do an apt-get install or download the firebird files, and from there on how to proceed with the setup.
Anyone can give me a detailed list of how to proceed with this pls? I tried google, and even got a stepwise install for firebird2.1, but when tried for 2.5 am not able to even download the files from console
Also I would like to know what should be the recommended hardware requirements for the machine to host this installation

The simple way
you can follow my guide for 2.1 and replace wherever is mentioned 2.1 with 2.5

https://help.ubuntu.com/community/Firebird2.1



2.you can also use the installer from firebird binary (.tar.gz one)
but is more complex , it needs an older libstdc++
http://firebirdsql.org/index.php?op=files&id=engine_250

3. you can compile from source code but that is harder and error prone

apt-get build-dep firebird2.5-super
get the source tar.bz2
http://sourceforge.net/projects/firebird/files/firebird/2.5-Release/Firebird-2.5.0.26074-0.tar.bz2/download
tar -cjvf Firebird-2.5.0.26074-0.tar.bz2

./configure --prefix=/opt/firebird2.5 --enable-superserver

make
make install

thx, i did try the follow the link posted before posting here, but somehow my system was not able to locate the firebird files, anything I may have missed in my Linux setup itself causing this here? I am connected to the internet thou...

I managed to install the 2.1 version of FB, but still not the 2.5 one. Is there a way I can upgrade the 2.1 to make it 2.5 from the console? (am new to linux and not yet got hold of the commands )
Using kubuntu 10.04LTS for this process...

OK so finally I downloaded the firebird2.5 file from firebirdsql.com, and extracted it on my linux machine, but do i need to do something with the install.sh to get it installed or another way or installing?

Here is the guide for Firebird 2.5 and Ubuntu 10.10

thanks for the guide, but am still on my Lucid, and tried to run the ./install.sh as in the guide. However when being asked for a new SYSDBA password, I entered my own, but then the operation failed with the following msg:

./scripts/postinstall.sh : line 112 : /opt/firebird/bin/gsec : cannot execute binary file

Where did I go wrong

in the end I installed maverick and used apt-get install to install fb2.5, Went like a charm. Sry for all the trouble caused by trying to stick to my lucid
