# The amount of time to wait while we have unknown package data before
27
 
# reporting an error to the server in response to an operation.
28
 
# The two common cases of this are:
29
 
# 1.  The server requested an operation that we've decided requires some
30
 
# dependencies, but we don't know the package ID of those dependencies.  It
31
 
# should only take a bit more than 10 minutes for that to be resolved by the
32
 
# package reporter.
33
 
# 2.  We lost some package data, for example by a deb archive becoming
34
 
# inaccessible for a while.  The earliest we can reasonably assume that to be
35
 
# resolved is in 60 minutes, when the smart cronjob runs again.
36
 
 
37
 
# So we'll give the problem one chance to resolve itself, by only waiting for
38
 
# one run of smart update.
