# Work around brutal packaging error courtesy of Microsoft.
# Unfortunately, the Microsoft repo includes a duplicate version of
# the libodbc1 package whose version is not in sync with the one
# shipped by the corresponding release of Ubuntu. If this one happens
# to be newer, then it can cause horrifyingly difficult to diagnose
# errors later on because there's a conflict between the
# default-available versions of libodbc1 and libodbc1:i386, which has
# in the past surfaced as an inability to install dependencies for
# Erlang. Thanks Microsoft. Please don't. Anyway, solution is to pin
# this repository at a lower priority than the Ubuntu standard
# packages, so the correct version of libodbc1 gets installed by
# default.
