weird this package is in ubuntu repo. Are you using 32-bit ubuntu ? or ARM ?
i am using a VMWARE ubuntu 32-bit system on WIN7 .
perhaps i need to do the clone using username root ?
nope ! the error is we assume that everybody use 64bit system (I think it is normal to assume that as all desktops are 64bits now)
So you are trying to install libc6-i386 that is a 32bit compatibility library for 64bit system (or something like that), and as you are in 32bit system, it isn’t present on ubuntu repo .
Would it be to hard for you to switch to 64bits ubuntu ?

okay ,i will try it right now ,but this will take about 1-2 hours to re-install a 64bits ubuntu and clone form github . after re-do it , I will update the result . keep in touch.
It would be good to handle 32bit, some embedded systems/SBCs are still 32bit.
I agree that it is good for support 32bit ubuntu . and I have a doubt that the official link：
http://ardupilot.org/dev/docs/building-px4-for-linux-with-make.html
doesn’t update the BUILD INSTRUCTIONS present here.
It will be more helpful to update the INSTRUCTIONS , because there will be more people (like me) will do as the official link instructions and got stuck . I won’t tell you that I had been stuck for five days, and when I input the error message which is made by follow the official link into google , there is no appropriate page that matches. and i keep on and on looking for good solutions .and as you know , I failed . So i think the official link is really a big trouble for new people.
The wiki is up to dat and must be follow , not this post…
@OXINARF Could you change the title in order to not confused people that read that. The wiki must be followed not this post
Hi ,khancyr . I follow your advice and re-install a 64bit ubuntu system.
After I tried the INSTRUCTION present in this post , i got stuck here for
an hour . the command window keeps display "cloning into ‘pymavlink’ "and doesn’t move on. how can i do with it ,just wait ? by the way , i am in china ,do i need a vpn connect and re-do the build command?

If it is cloning you have to wait for it to get all the data, but one hour seems way too long, specially for pymavlink. I’ve heard of some constraints in China for GitHub but I’m not sure if that’s still in place or not and if it is affecting the speed at which you get content.
till now ,it has been stuck in " Cloning into ‘pymavlink’. .“for 4 hours.
I have already tried to visit link " https://github.com/ArduPilot/pymavlink” on firefox and i got this page
that means that i can visit the link:
https://github.com/ArduPilot/pymavlink
but when use command “git://github.com/ArduPilot/pymavlink.git” it stucks and seem stuck forever.
what can i do with it ?just wait another 3 hours?
You can try editing the .gitmodules file inside the ArduPilot folder and change the git:// to https:// since I’ve read that some people behind firewalls can’t use the git protocol. But you’ve got other repositories so it is strange if that is the issue.
i am trying your instructions.
at first i end the comman line by input’ctrl+c" ,it looks
^CTraceback (most recent call last):

Interrupted
then i modified the .gitmodules file ,and it seems it’s read-only file ,can’t be modified .
here is the operation that i made and corresponding result 
after that ,i input the command " ./waf copter ",now it stuck again at
./waf copter
Waf: Entering directory `/home/wei/ardupilot/build/px4-v2'
[1/4] Running Submodule update: PX4FirmwareHow do you do not have permissions to save the file? I would reboot and try again, that looks very strange.

now i use sudo gedit .gitmodules to open .gitmodules and suffcessfully change the the git:// to https://
