How to install kerberos client on Ubuntu 22

I was asked to integrate some new Ubuntu 22 boxes into an existing Kerberos instrastructure. I found several references for installing a kerberos client which all start with:

sudo apt-get install krb5-user

Unfortinately this results in:

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Package krb5-user 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 'krb5-user' has no installation candidate

I do not have a lot of experience with Ubuntu so maybe this is normal. Is Kerberos not supported on Ubuntu? If it is supported, what do I do to fix this?
