The Ubuntu Website states that Ubuntu Core is
Now available on a wide range of 32 and 64-bit ARM and X86 platforms.
The following page says
64-bit PC (AMD64) snappy image Choose this to take full advantage of computers based on the AMD64 or EM64T architecture (e.g., Athlon64, Opteron, EM64T Xeon, Core 2). If you have a non-64-bit processor made by AMD, or if you need full support for 32-bit code, use the Intel x86 images instead.
But there is no link to the x86 32 bit image on the page.
Searching around, I find this:
Currently, no 32-bit version of Snappy Ubuntu Core is built.
Is a 32 bit X86 version of snappy core available, and if so, where is it?
