Re: exportfs: /anyfolder does not support NFS export

again, everything from the beginning...

purge any nfs related things, and install fresh , from the beginning....now....

root@debian:~# apt-get remove --purge nfs-common librpcsecgss3 libnfsidmap2 nfs-kernel-server rpcbind
The following packages will be REMOVED:
  libnfsidmap2* nfs-common* nfs-kernel-server* rpcbind*

(compiled in kernel, not able to simply kill, umount from proc probably solve, but reboot will be next)

root@debian:~# mount | grep nfs
nfsd on /proc/fs/nfsd type nfsd (rw,relatime)

manually:
removed `/var/lib/nfs/export-lock'
removed `/var/lib/nfs/.etab.lock'
rmdir /var/lib/nfs/

reboot.
