# The amount of time to wait while we have unknown package data before
# reporting an error to the server in response to an operation.
# The two common cases of this are:
# 1.  The server requested an operation that we've decided requires some
# dependencies, but we don't know the package ID of those dependencies.  It
# should only take a bit more than 10 minutes for that to be resolved by the
# package reporter.
# 2.  We lost some package data, for example by a deb archive becoming
# inaccessible for a while.  The earliest we can reasonably assume that to be
# resolved is in 60 minutes, when the package reporter runs again.

# So we'll give the problem one chance to resolve itself, by only waiting for
# one run of apt-update.
