</pre><div>Now we're ready for modify the apt repo sources for our wished new architecture, you should edit the file /etc/apt/sources.list and change the repositories as (I left here a sources.list sample file)If we want to set any repository you must add the tags: <br> [arch=i386] intel 32 bits <br> [arch=armel] ARM soft float 32 bits <br> [arch=armhf] ARM hard float 32 bits <br> or both: <br> [arch=armel,armhf] ARM soft/hard float repo 32 bits <br> The sources repositories not need to be tagged due sources repositories be the same for all architectures. </div><pre># deb cdrom:[Ubuntu 12.04.4 LTS _Precise Pangolin_ - Release i386 (20140204)]/ precise main restricted

You should add here the repositories for every architecture ...
After that we must execute:
<pre>apt-get update
</pre>
= Install ARM packages =
If you wish install a new package (in our case we install openssl library) you should do:
<pre>mcaro@mcaro-vm-u12:~$ apt-cache search libssl
libssl-dev - SSL development libraries, header files and documentation
libssl-doc - SSL development documentation documentation
libssl1.0.0 - SSL shared libraries
libssl1.0.0-dbg - Symbol tables for libssl and libcrypto
dcmtk - OFFIS DICOM toolkit command line utilities
libcherokee-mod-libssl - Cherokee web server - SSL crypto functions plugin
libdcmtk2 - OFFIS DICOM toolkit runtime libraries
libdcmtk2-dev - OFFIS DICOM toolkit development libraries and headers
libssl-ocaml - OCaml bindings for OpenSSL (runtime)
libssl-ocaml-dev - OCaml bindings for OpenSSL
libssl0.9.8 - SSL shared libraries
libssl0.9.8-dbg - Symbol tables for libssl and libcrypto
libsslcommon2 - enterprise messaging system - common SSL libraries
libsslcommon2-dev - enterprise messaging system - common SSL development files
</pre>
and after found your desired library:
<pre>sudo apt-get install libssl1.0.0:armhf
</pre>
Adding ":armhf" at end you set the ARM hard floating version to set installed. If you don't set the arch apt-get will install your default arch package (in this case i386).
