There are a ton of reasons why Debian may have an older version of
an upstream release. For example, and I hasten to point out that
the following list is by no means exhaustive, and not all of the
possibilities are common:
* The Debian package maintainer is dead, but nobody noticed it yet, and
nobody has wanted an update badly enough to do an NMU or to adopt the
* The upstream release is actually a fake. It's a trojan, which was
put there by the NSA in order to infiltrate the CIA mainframe. The
Debian package maintainer noticed this and uploaded that version of
the package to non-free instead of main, since the trojan code does
not come with proper source.
* Upstream has moved the RSS feed for new releases without notifying
the old feed of the move, so the Debian package maintainer missed that,
and doesn't actually know about the new release. Due to a complicated
series of happenstance involving rainbows, midget unicorns, and the
ongoing rewrite of the Netsurf web browser, the Debian package maintainer
is not able to find the new feed because it would require doing a
web search and their browser doesn't have working form support now.
No other browser is available on the Amiga they're using as their only
* The new release is requested by insistent Hurd porters, and the Debian
package maintainer absolutely loathes the Hurd, and will refuse to
upload any packages that work on the Hurd.
* The Debian package maintainer suffers from mental problems cause by
reading debian-devel too much, and now has a nervous breakdown every
time they recognize a name as someone whom they've seen on the list.
* The Debian development process is being sabotaged by Microsoft sending
people to the developers' houses pretending to be TV license checkers
or Jehova's witnesses every time they detect, using the hardware
wireless keylogger embedded in every PC, that the developer is trying
to run any Debian packaging command.
* Apple is also sabotaging Debian by paying me to write snarky e-mails on
Debian mailing lists to distract everyone from working on the actual
release, so that we can get past the freeze and start uploading things
again without having to worry that it breaks things in ways that
makes the freeze longer.
