I use nfs to copy files from an Ubuntu development machine to an embedded system board. The embedded board uses an older kernel and Linux which is not practical to update. It uses NFS v2 but Ubuntu 18.04LTS has NFS v2 disabled. The process works fine on an older Ubuntu 14.04LTS machine with v2 enabled.
How do I go about enabling NFS v2 on Ubuntu 18.04LTS?
