Trying to install Samba on Ubuntu 20.04 Desktop running on Raspberry Pi

Hi I recently installed Ubuntu Server 20.04 on my Pi and then installed Ubuntu Desktop.

I am now trying to install Samba so I can make a share with my Windows system but I am getting the following error when trying sudo apt install samba samba-common-bin or using:

chewie@ubuntu:~$ sudo apt install samba samba-common-bin
Reading package lists... Done
Building dependency tree

Package samba-common-bin is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

However the following packages replace it: samba-libs
E: Package 'samba' has no installation candidate
E: Package 'samba-common-bin' has no installation candidate

Can anyone help or tell me why it isn't working?

Thanks so much for reading!
