Buffer_ is not a symbol name prefix used by python.

If it was PyBuffer_ then maybe it would have come from python itself.
ujson appears to be compiled extension, did you missbuilt it?
And it itself defines this
FASTCALL_ATTR INLINE_PREFIX void FASTCALL_MSVC Buffer_AppendShortHexUnchecked
(char *outputOffset, unsigned short value)
{
*(outputOffset++) = g_hexChars[(value & 0xf000) >> 12];
*(outputOffset++) = g_hexChars[(value & 0x0f00) >> 8];
*(outputOffset++) = g_hexChars[(value & 0x00f0) >> 4];
*(outputOffset++) = g_hexChars[(value & 0x000f) >> 0];
}
Which is possibly now inlined, instead of being an exported symbol?
Compiler can choose to do that.
BTW. python-ujson is available on ubuntu bionic
$ sudo apt install python-ujson
$ python2 -c 'import ujson; print ujson'
I am afraid this is a bug with pip's ujson, not with ubuntu's python2.
The one that we provide is the same version 1.35. Maybe you can remove
your self-built / pip install ujson and install our distro provided one
instead with sudo apt install python-ujson?
