Comment 14 for bug 222194

Hi i'm also having trouble with ubuntu-xen-server and ubuntu-xen-desktop. However the unmet dependencies are not exactly the same reported here, so if a new bug report must be filled just let me know

>> ubuntu-xen-server

 sudo apt-get install ubuntu-xen-server

The following packages have unmet dependencies:
  ubuntu-xen-server: Depends: python-xen-3.2 but it is not going to be installed
                     Depends: xen-utils-3.2 but it is not going to be installed

>> ubuntu-xen-desktop

 sudo apt-get install ubuntu-xen-desktop

The following packages have unmet dependencies:
  ubuntu-xen-desktop: Depends: python-xen-3.2 but it is not going to be installed
                      Depends: xen-utils-3.2 but it is not going to be installed
                      Depends: xenman but it is not installable

If i dig a little bit more i've found:

sudo apt-get install python-xen-3.2

The following packages have unmet dependencies:
  python-xen-3.2: Depends: python-dev but it is not going to be installed
E: Broken packages

 sudo apt-get install python-dev

The following packages have unmet dependencies:
  python-dev: Depends: python2.5-dev (>= 2.5.2) but it is not going to be installed
E: Broken packages

sudo apt-get install xen-utils-3.2

The following packages have unmet dependencies:
  xen-utils-3.2: Depends: python-xen-3.2 but it is not going to be installed
E: Broken packages

 sudo apt-get install xenman

Package xenman is not available, but is referred to by another package.

E: Package xenman has no installation candidate

So the source for this bug is the python-dev version problem and the no availability of xenman.

With aptitude the proposed solution is:

sudo aptitude install ubuntu-xen-server

  python2.5-dev

so it seems that python-xen needs to be upgraded to reflect the new python package ?? about xenman it seems that was replaced with convirt but this is not available yet at the repos...
