ok, so I was getting ready to do a LSF using Ubuntu 11.10 as the host file. But the LSF book says I need xz 5.0.3 as a pre-requisite for doing it. When I tried to compile and install 5.0.3 I had to reinstall so my system was usable without any errors.

How can I upgrade to zx 5.0.3 from the current 5.0.2 so that I can have everything I need?

Wat is 'to do LSF'? What do you mean by 'Using Ubuntu 11.10 as the host file'? Which book do you refer to? What exactly did you do to compile and install xz 5.0.3? What happened that made you decide to completely reinstall? –  jippie Apr 14 '12 at 16:16
LSF was supposed to be LFS (Linux From Scratch). so you can design your own Linux based OS. I would be using Ubuntu as my host OS, meaning that the kernel and compilation programs come from Ubuntu. When I compiled XZ 5.0.3 i followed the directions included in with the source code. did ./configure make and makeinstall from cli. after the botched installation I could not remove or downgrade to the original version of XZ that was on my computer. I reinstalled because I started getting various errors from different programs that I use on a daily basis that relied on an uncorrupted version of XZ –  Edward Apr 17 '12 at 17:51
First, 11.10 has reached end of life and is no longer supported so you should switch to 12.04 or 12.10. Second, it sounds like you need to read the LFS instructions again as you seem to have installed onto the host system instead of into the new system chroot. –  psusi Apr 17 '13 at 18:06
