Trying Ubuntu instead of waiting more for Android update

Hello, I am not an OS specialist; just a basic smartphone user. As many of you, I have been waiting for the upgrade from Android 4.2 to Android 4.4. After having read the entire discussion about that issue, I am convinced that an upgrade to Android 4.4 won’t make the FP1(U) last much more than one or two years from now. Can anyone tell me if a complete switch to Ubuntu is possible with the FP1U and would make it a true, longlasting , sustainable device? Would I encounter the same ugrade limits in the open source universe? Can anyone please tell me how to proceed or where I could find the usermanual? Is there already a forum with this topic which I did not come through? Many thanks
