Apport retracing service says my packages are out of date but shows very similar version numbers

[Thomas A. F. Thorne]

Over in : https://bugs.launchpad.net/ubuntu/+source/xorg-server-lts-utopic/+bug/1462308 I got a message starting:

Thank you for your report!

However, processing it in order to get sufficient information for the
developers failed (it does not generate a useful symbolic stack trace). This
might be caused by some outdated packages which were installed on your system
at the time of the report:

outdated debug symbol package for libudev1: package version 204-5ubuntu20.12 dbgsym version 204-5ubuntu20
outdated debug symbol package for libfreetype6: package version 2.5.2-1ubuntu2.4 dbgsym version 2.5.2-1ubuntu2
no debug symbol package found for libbz2-1.0
outdated debug symbol package for libcgmanager0: package version 0.24-0ubuntu7.3 dbgsym version 0.24-0ubuntu5

Please upgrade your system to the latest package versions. If you still
encounter the crash, please file a new report.

Thank you for your understanding, and sorry for the inconvenience!

Which seemed fair enough to me until I took a closer look at the packages. I noticed that I had not packages to update:

I have just done an update and then
$ sudo apt-get upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
Calculating upgrade... Done
0 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade.

That I had not updated any of the listed packages recently (based on /var/log/apt/histroy) and that I had rebooted at 14:00 the previous day which was long after the last time I was asked to reboot following and update.

Looking at those numbers it seems that the dbgsm system has dropped the lesser digits and then said I was out of date?
I think there is possibly a bug with that. I am raising this ticket to check if those numbers are equivalent and the apport system is dropping the last digits off the version number and getting confused.

If you look at libcgmanager0, it is clearly not an issue of dropping the lesser digits. Its likely that there was an issue with the ddebs server and for example 204-5ubuntu20.12 wasn't available at the time of retracing. Looking at it now we can see 20.19 is available.

So you are saying that the debug packages were probably unavailable and that caused the error. The confusing part was that the error message said "Please upgrade your system to the latest package versions." when what it needed to say was something like "Please try generating this report later once the debug symbol packages are available."
