After a lot of digging, I found a solution/workaround. The problem is
the nfs version, in short:
sudo mount -t nfs o nfsvers=2 server:/<serverdir> <localdir>
does the trick. Anyway, here is what happens without specifying the
nfsvers option:
sudo mount -t nfs -v server:/<serverdir> <localdir>
mount.nfs: timeout set for Sat May 21 11:59:43 2016
mount.nfs: trying text-based options 'vers=4,addr=192.168.1.133,clientaddr=192.168.1.25'
mount.nfs: mount(2): Stale file handle
Version 3 also does not work:
sudo mount -t nfs -v o nfsvers=3 server:/<serverdir> <localdir>
mount.nfs: timeout set for Sat May 21 12:00:12 2016
mount.nfs: trying text-based options 'nfsvers=3,addr=192.168.1.133'
mount.nfs: prog 100003, trying vers=3, prot=6
mount.nfs: trying 192.168.1.133 prog 100003 vers 3 prot TCP port 2049
mount.nfs: prog 100005, trying vers=3, prot=17
mount.nfs: trying 192.168.1.133 prog 100005 vers 3 prot UDP port 55187
mount.nfs: mount(2): Stale file handle
Finally, this does work:
sudo mount -t nfs -v o nfsvers=2 server:/<serverdir> <localdir>
mount.nfs: timeout set for Sat May 21 12:00:33 2016
mount.nfs: trying text-based options 'nfsvers=2,addr=192.168.1.133'
mount.nfs: prog 100003, trying vers=2, prot=6
mount.nfs: trying 192.168.1.133 prog 100003 vers 2 prot TCP port 2049
mount.nfs: prog 100005, trying vers=1, prot=17
mount.nfs: trying 192.168.1.133 prog 100005 vers 1 prot UDP port 34856
Again, the NFS server runs Ubuntu Desktop 14.04, nfs export is done
without any specific options wrt the nfs version.
So maybe this is not a bug per se and it is just that the default for
the version has changed, but IMHO, a meaningful error message would be
*a lot* better than just timing out without any additional information.

Title:
mount -t nfs not working in ubuntu 16.04
Status in util-linux package in Ubuntu:
New
Bug description:
After upgrading from 15.10 to 16.04, the command
sudo mount -t nfs Biest:/<path_to_shared_dir> /home/manfred/BigDisk/
times out without any further error reporting:
mount.nfs: Connection timed out
It worked on the same machine before the upgrade, and it still works
from both a 14.04 and a 15.10 machine. The file server is running
14.04.
Additional info: I just updated today (05/17/2016). Let me know what
else you need. Other people seem to have the same or similar problems,
but no official bug report, fix, or workaround to be found. Only
viable option I have now is to downgrade to 15.10.
