While updating my natty install on my beagle board xm, I ran into the following
Preparing to replace libjpeg-turbo62 1.1.90-1inaro6 (using .../libjpeg-turbo62_1.1.90-1inaro6_armel.deb) ... DEB_HOST_MULTIARCH is not a supported variable name at /usr/bin/dpkg-architecture line 214.
That's an error from dpkg-architecture, which is part of dpkg-dev. I presume the version of dpkg-dev on your board is too old to know about DEB_HOST_MULTIARCH (prior to 1.16.0).
This doesn't make much sense as
dpkg-query -l multiarch-support
That's not the package that's complaining.
Wookey
