Hi while installing openldap when i enter the command:
"apt-get install slapd"
I get the following output
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.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
slapd : Depends: libldap-2.4-2 (= 2.4.28-1.1ubuntu4.1) but 2.4.28-1.1ubuntu4.2 is to be installed
E: Unable to correct problems, you have held broken packages.


Please help.

Hi,

we should be able to help you, but need more information. So, I have a few questions.

- Did you do an "apt-get update" before doing "apt-get install slapd"?
- Have you done and "apt-get upgrade" recently?
- Have you installed any packages "by hand"? (Eg download .deb from random place and install)?
- Can you post your /etc/apt/sources.list and /etc/apt/sources.list.d/* (if any)
- You say this is "debian based" yet the package version strings have "ubuntu" in them": can you explain why?

Evo2.

Thanks for the reply.

I run update and upgrade just before running this command. I want to install "openldap" and for this I am running the command apt-get install slapd.

Below is the output of sources list.
I am running this distro:
