Lab LFS258 9.2 "Package 'nfs-common' has no installation candidate"

For task 5 I am trying to install the NFS client package on the worker node using the following command:

sudo apt install -y nfs-common

However, the installation fails with the error below:

student@worker:(⎈|default):~$ sudo apt install -y nfs-common
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Package nfs-common 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

E: Package 'nfs-common' has no installation candidate

Has anyone seen this before, or can suggest what might be causing the package to be unavailable on this node? I would appreciate any guidance on how to troubleshoot or resolve the issue.
