How to meet depends requirements for libldap-2.4-2

Question

I am trying to install the libldap2-dev package.

sudo apt-get install libldap2-dev

I get the following error:

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:
 libldap2-dev : Depends: libldap-2.4-2 (= 2.4.31-1+nmu2ubuntu8.2) but 2.4.31-1+nmu2ubuntu8.3 is to be installed
E: Unable to correct problems, you have held broken packages.

It looks like I need to install 2.4.31-1+nmu2ubuntu8.2 not 2.4.31-1+nmu2ubuntu8.3

I've tried:

sudo apt-get install libldap2-dev=2.4.31-1+nmu2ubuntu8.2

I get the same error when doing so.

I've also found this but am still having trouble: Here

Solution

Resolved with

sudo aptitude install libldap2-dev

At first it suggested to do nothing, I've selected No, then it suggested to downgrade my current install to proper version. I've selected Yes.

Your sources are broken. The latest version of libldap2-dev in Trusty depends on version 2.4.31-1+nmu2ubuntu8.3 of libldap-2.4-2 (note that both packages have the same version number). Installing an out-of-date version of libldap2-dev is not the correct thing to do. Rather, you should figure out why your archive mirror is not supplying the correct version of it.
