Help - running into trouble updating Xubuntu

[Carsten Agger]

I'm running Xubuntu dapper and trying to update to Edgy.

After following the instructions on

https://help.ubuntu.com/community/EdgyUpgrades?#head-d8c4cd1dd987e54723fef2760b37f9279487551f

I'm getting this output from dpkg --configure -a:
--------
dpkg: dependency problems prevent configuration of libxdmcp6:
  libxdmcp6 depends on x11-common (>= 1:7.0.0); however:
   Version of x11-common on system is 7.0.0-0ubuntu45.

What's the problem here?

If I try to remedy the problem with a sudo apt-get -f install,

here's what I get:
agger at mahadev:~$ sudo apt-get  -f install

What's the problem? Should I reboot my system as is (I really don't feel 
like doing that ...!) or can the situation be fixed somehow?
