ubuntu 16.04 add multiarch armhf

Asked by clonephone82

Hello,

Today I tried to add multiarch armhf to my ubunt 16.04 installation. I followed that guide here https://wiki.debian.org/Multiarch/HOWTO

so I try:

sudo dpkg --add-architecture armhf
sudo apt-get update

Then I get a lot off update errors so nothing for armhf is installed. What is the right way to add multiarch armhf on ubuntu 16.04 ?
My system is up to date.

many thanks
cheers

I want to do some cross compiling for Beagle Bone Black. I followed that tutorial here http://exploringbeaglebone.com/chapter7/
But the guy from the webpage do not use Ubuntu but I think it should be work or I am wrong here.

It would be great if you can help me.

If I remove the armhf architecture everything works fine when i use apt-get update. So the errors are only from that foreign arch I think

thx

Your approach is not wrong. The only problem is that the .deb package files for architectures different from amd64 and i386 are not available in the standard archives, but on a special repository server.

Try the following modification in the sources.list file(s):

Each line such as
deb http://at.archive.ubuntu.com/ubuntu/ xenial main universe

has to be converted into these two lines:
deb [arch=amd64,i386] http://at.archive.ubuntu.com/ubuntu/ xenial main universe
deb [arch=armhf] http://ports.ubuntu.com/ubuntu-ports xenial main universe

(similar for security.ubuntu.com, also here the armhf .deb files need the ports.ubuntu.com server)

So I think it is better to use a docker container for that because other wise i crash my system because I am not a pro in reading that source.list stuff

many thanks
