The message given by the apport retracer is rather misleading, "might be
caused by some outdated packages" leads one to believe that it may be
something on their system, when in fact it isn't. The debug symbol
packages come from the ddebs.ubuntu.com server and there seem to be none
for libjbig0 (the only one I checked). So really the message given by
apport should be changed to be conditional so that if the 'outdated_msg'
(a variable in apport's code) includes the string "debug symbol package"
then "outdated packages… installed on your system" should not appear.
I'll open a bug report for that.

We can't really.
