SQL server installation error in Linux

I have been trying to install the SQL server on Ubuntu and following the documentation from the given link: https://learn.microsoft.com/en-us/sql/linux/quickstart-install-connect-ubuntu?view=sql-server-linux-ver15&preserve-view=true#install .

The following error occurred while executing 'sudo apt-get install -y mssql-server' command.

Error: "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 resolve the situation:

The following packages have unmet dependencies:
mssql-server : Depends: libldap-2.4-2 but it is not installable
E: Unable to correct problems, you have held broken packages."

Start with the linked Microsoft SQL Server on Ubuntu installation documentation and reproduce the sudo apt-get install -y mssql-server command on the affected Ubuntu environment. Investigate why libldap-2.4-2 is unavailable and document or verify a supported installation path; done means the documented installation completes without the unmet-dependency error.
