Hi,

during a test with piuparts I noticed your package fails to upgrade from
'wheezy'.

That failing upgrade scenario is an upgrade of education-standalone
with --install-recommends from wheezy to jessie. That's a lot of
packages.

According to http://debian.semistable.com/debgraph.out.html mono is
responsible for a lot of circular dependencies :-(

Hi Andreas,

Is this upgrade problem still reproducible?  There was an upload of dpkg
between you filing this upload.  I do realise this does not affect the
mono dependency cycle - but if the upgrade now works, then it was
probably a trigger cycle.

I just did a wheezy->jessie test upgrade with libmono-corlib4.0-cil
initially installed and it went fine.

Best wishes,

Sadly upgrades do not split package sets the same place every time, so
the cycle can still be present even if an upgrade succeeds.

And I just noticed several mono related cycles is reported in
<URL: http://debian.semistable.com/debgraph.out.html >,  See details in
<URL: http://debian.semistable.com/dot/mono-runtime-sgen_testing.png >,
<URL: http://debian.semistable.com/dot/libmono-system-web4.0-cil_stable.png >,
<URL: http://debian.semistable.com/dot/libmono-system-servicemodel4.0a-cil_stable.png >
and <URL: http://debian.semistable.com/dot/monodoc-manual_stable.png >.
Fixing those cycles would make the mono upgrade success more
predictable.

thanks

With Mono binary packages being consolidated into 3 packages only
(+ debug packages), such circular dependencies should be a thing of the past.
