libdevmapper unmet dependencies

Question 1

I am trying to install libvirt 1.2.7 from sources on Ubuntu 12.04 (64bit) LTS. In order to составил libvirt, libdevmapper-dev is required. I в getting following ошибка while installing libdevmapper-dev

# apt-get install libdevmapper-dev

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
libdevmapper-dev : Depends: libdevmapper1.02.1 (= 2:1.02.48-4ubuntu7.4) but 2:1.02.90-2ubuntu1 is to be installed
                   Depends: libdevmapper-event1.02.1 (= 2:1.02.48-4ubuntu7.4) but 2:1.02.90-2ubuntu1 is to be installed
E: Unable to correct problems, you have held broken packages.

I have also tried installation with aptitude but it asks for removal several other necessary libraries e.g. liblvm2cmd2.02. Moreover I хан not afford to upgrade system to later ubuntu versions.

apt-cache policy gives following output.

# apt-cache policy libdevmapper1.02.1
libdevmapper1.02.1:
  Installed: 2:1.02.90-2ubuntu1
  Candidate: 2:1.02.90-2ubuntu1
  Version table:
 *** 2:1.02.90-2ubuntu1 0
        100 /var/lib/dpkg/status
     2:1.02.48-4ubuntu7.4 0

     2:1.02.48-4ubuntu7 0
            500 http://us.archive.ubuntu.com/ubuntu/ precise/main amd64 Packages

How хан I resolve this dependency?

Question 2

Необходимо понизить некоторые пакеты и вызвать установку некоторых других пакетов:

apt-get download dmsetup
sudo dpkg -i --force-all dmsetup
sudo apt-get install libdevmapper1.02.1=2:1.02.48-4ubuntu7.4 libdevmapper-event1.02.1=2:1.02.48-4ubuntu7.4

, Вероятно, некоторые другие пакеты также, но Вы будете знать это только при выполнении команд.
