Why can't I install these packages?

The output you provided on apt-cache policy
confirms my suspicion about outdated lists.
For the example of krb5-multidev
in 12.04 you should see version 1.10+dfsg~beta1-2ubuntu0.3
as a candidate provided through precise-updates
.
krb5-multidev:
Installed: 1.10+dfsg~beta1-2ubuntu0.3
Candidate: 1.10+dfsg~beta1-2ubuntu0.3
Version table:
*** 1.10+dfsg~beta1-2ubuntu0.3 0
500 http://nl.archive.ubuntu.com/ubuntu/ precise-updates/main amd64 Packages
500 http://security.ubuntu.com/ubuntu/ precise-security/main amd64 Packages
100 /var/lib/dpkg/status
1.10+dfsg~beta1-2 0
500 http://nl.archive.ubuntu.com/ubuntu/ precise/main amd64 Packages
So, as I already suggested in the comments, run
sudo apt-get update
And you should be all set (retry the installation and also properly update your system!).

I want to install curl library in ubuntu 12.04 LTS. For that i use the following command sudo apt-get install libcurl4-openssl-dev. but i got the errors as
ajay@ajay-K54L:~$ sudo apt-get install libcurl4-openssl-dev [sudo] password for ajay: Reading package lists... Done Building dependency tree Reading state information... Done 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.

Whenever i try to install thee dependencies, it shows that packages already installed:

What do I need to do?
I have tried following command
apt-cache policy libkrb5-3 krb5-multidev libk5crypto3 libgssapi-krb5-2 libcurl4-openssl-dev
and it gives me output as:
ibkrb5-3: Installed: 1.10+dfsg~beta1-2ubuntu0.3 Candidate: 1.10+dfsg~beta1-2ubuntu0.3 Version table: *** 1.10+dfsg~beta1-2ubuntu0.3 0 100 /var/lib/dpkg/status 1.10+dfsg~beta1-2 0 500 http://in.archive.ubuntu.com/ubuntu/ precise/main amd64 Packages krb5-multidev: Installed: (none) Candidate: 1.10+dfsg~beta1-2 Version table: 1.10+dfsg~beta1-2 0 500 http://in.archive.ubuntu.com/ubuntu/ precise/main amd64 Packages libk5crypto3: Installed: 1.10+dfsg~beta1-2ubuntu0.3 Candidate: 1.10+dfsg~beta1-2ubuntu0.3 Version table: *** 1.10+dfsg~beta1-2ubuntu0.3 0 100 /var/lib/dpkg/status 1.10+dfsg~beta1-2 0 500 http://in.archive.ubuntu.com/ubuntu/ precise/main amd64 Packages libgssapi-krb5-2: Installed: 1.10+dfsg~beta1-2ubuntu0.3 Candidate: 1.10+dfsg~beta1-2ubuntu0.3 Version table: *** 1.10+dfsg~beta1-2ubuntu0.3 0 100 /var/lib/dpkg/status 1.10+dfsg~beta1-2 0 500 http://in.archive.ubuntu.com/ubuntu/ precise/main amd64 Packages libcurl4-openssl-dev: Installed: (none) Candidate: 7.22.0-3ubuntu4 Version table: 7.22.0-3ubuntu4 0 500 http://in.archive.ubuntu.com/ubuntu/ precise/main amd64 Packages

gertvdijk about 11 yearsWelcome to Ask Ubuntu! Could you try to update your package lists?
sudo apt-get update
and then re-attempt the installation. It appears yours are out of date. If that still fails, please provide the output ofapt-cache policy libkrb5-3 krb5-multidev libk5crypto3 libgssapi-krb5-2 libcurl4-openssl-dev
