I don't see specific UDP options in the two /etc/default/nfs-* files
attached to this bug, so there was nothing to convert to
/etc/nfs.conf.d/local.conf regarding UDP. It's probably the default that
changed (before udp
It was only partly successful, it failed to merge udp = y into the new
conf.
Also Ubuntu's decision to compile their kernels without UDP support is
dumb. It does not make a huge difference in size or speed of the kernel
and it does eliminate legacy support as the original NFS version 2 and
The kernel we ship has nfs udp disabled, I missed that you were running
a custom kernel. But thanks for the feedback.
I think we need to remove or add a big fat comment to the obsolete
/etc/default/nfs-* files, and I filed a bug for it:
This is just plain WRONG. The issue is NOT the kernel, upstream or
otherwise. I am using 5.17.7 compiled directly from kernel source off
of kernel.org, and was using the SAME kernel under 20.04.
The issue was your new configuration file, /etc/nfs.conf, that did not
exist prior to 22.04, and
NFS UDP was disabled in the upstream kernel[1] in 2019, and the first
Ubuntu release with that change was 20.10 (groovy). I didn't find this
change in the 20.10 release notes, and added this bit to the 22.04
release notes[2] about a month before the release:
"""
UDP disabled for NFS mounts

Thank you very much. The disabling of udp by default is what
broke version 2 and version 3, and since TCP were not part of the NFS
specification for either of these versions, making it the default makes
ZERO sense.

I did some tests, and looks like I was able to configure ubuntu 22.04 to
export NFS v2. I was able to mount from an ubuntu 14.04 machine
specifying vers=2:
t1 is trusty (14.04), j1 is jammy (22.04):
root@t1:~# rpcinfo -s j1-nfs-server

Hi,
I believe NFS version 2 is no longer supported. I will check when that
was dropped exactly.
Regarding v3, the UDP transport is no longer available, only TCP. Can
you check if your v3 clients are forcing UDP perhaps, and thus failing?
It would in fact be helpful if you could show the error
ubuntu-bug included mounts of other file systems on this machine, but it
is the EXPORTS that aren't working NOT the mounts from other systems.
Here is the content of /etc/exports:
