Hello,
I am having trouble mounting to ANY Linux NFS server (elsewhere on my network) on WSL2 (Ubuntu 20.04) getting mount.nfs: No Such device. I have reas this could be a problem with the installed NFS Kernel modules. I have issued all the apt-get commands for mount, nfs client packages, nfs library and lock packages, etc.

If these NFS kernel modules are out of whack, how can this be repaired? This is fresh Ubuntu 20.04 install from the Microsoft App Store and fresh NFS install and I have rebooted the WIn 10 machine afterwards.

I am running Win 10 Build 18363.

There is nothing inside the /usr/lib/modules or the /lib/modules directory.

Issuing "systemctl list-unit-files | grep -i nfs" shows:

proc-fs-nfsd.mount static enabled
nfs-blkmap.service disabled enabled
nfs-common.service masked enabled
nfs-config.service static enabled
nfs-idmapd.service static enabled
nfs-kernel-server.service enabled
nfs-mountd.server static enabled
nfs-server.service enabled enabled
nfs-utils.service static enabled
nfs-client.target.service enabled enabled

Thank you for any assistance!

I have reas this could be a problem with the installed NFS Kernel modules.

There are no kernel modules (and no Linux kernel) in WSL1. Academically same #2869. NFS is available in WSL2 as of 20H1 aka version 2004 aka build 19041.

Hello,
Thank you for your reply! I mistakenly thought downloading the latest Ubuntu 20.04 from the Win 10 App Store was WSL2. My machine does indicate Win 10 Build 1909. I do have access to some 2004 Win 10 machines so I will re-try there. Thank you very much!

So, still no way to mount nfs with utf-8 file names when windows is itself in virtual machine.
wsl1 have not got kernel modules, and wsl2 requires the physical virtualization available.

Thanks! Tested on Version 2004 Build 19041.610 and it works!
