Hello Vic. Just to let you know, I'd successfully installed the IRIS!!
The problem was on the path thar I was trying to install it. I intended to install it on a partition NTFS (I have a Dual Boot into my machine) and it shoud help me to code in both the systems.

So I'd choosed other path Into my Linux partition and just use the NFTF partition to all my database, with this I was able to install the IRIS on Ubuntu.

Thank you so much for your time.
