Error in installing libssl-dev and libssl1.0-dev in Ubuntu

I am trying to install libssl-dev and libssl1.0-dev in Ubuntu 18.04 via the following command:

sudo apt-get -y install build-essential openssl libssl-dev libssl1.0 libgl1-mesa-dev libqt5x11extras5

I am getting the following output:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Note, selecting 'libssl1.0-dev' for regex 'libssl1.0'
Note, selecting 'libssl1.0.0' for regex 'libssl1.0'
Note, selecting 'libssl1.0.2' for regex 'libssl1.0'
build-essential is already the newest version (12.4ubuntu1).
libqt5x11extras5 is already the newest version (5.9.5-0ubuntu1).
libqt5x11extras5 set to manually installed.
libgl1-mesa-dev is already the newest version (20.0.8-0ubuntu1~18.04.1).

libssl-dev is already the newest version (1.1.1-1ubuntu2.1~18.04.20).
libssl1.0.0 is already the newest version (1.0.2n-1ubuntu5.10).
openssl is already the newest version (1.1.1-1ubuntu2.1~18.04.20).
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:
 libssl-dev : Conflicts: libssl1.0-dev but 1.0.2n-1ubuntu5.10 is to be installed
 libssl1.0-dev : Conflicts: libssl-dev but 1.1.1-1ubuntu2.1~18.04.20 is to be installed
E: Unable to correct problems, you have held broken packages.**

How do I solve these errors?
