Kerberized NFS mounts stopped working on Raspberry Pi starting with Ubuntu 21.10.
The reason is that the kernel module rpcsec_gss_krb5 which is needed for establishing a kerberos protected NFS connection to the server has been removed from the kernel image and put to linux-modules-extra package.
In my particular case it was:
linux-image-5.19.0-1011-raspi
Trying to mount a the NFS share resulted in the following error message:
mount.nfs: an incorrect mount option was specified

I did not find any documentation stating that the linux-modules-extra package needs to be installed and the kernel module has to be loaded manually.

So my expectation would be either to update the documentation or to move rpcsec_gss_krb5 back to the kernel image.
