The error means the /usr/lib/libaugeas.so.0 copied into the appliance
doesn't contain the AUGEAS_0.16.0 symbol versions.  Maybe it's some
old version of the augeas library.

If you run `nm -D /usr/lib/libaugeas.so.0' on the host you should
hopefully see AUGEAS_0.16.0 somewhere in the output.  eg. on my Fedora
machine (so slightly different) I see:

$ nm -D /usr/lib64/libaugeas.so.0 | grep AUGEAS_0.16.0
0000000000000000 A AUGEAS_0.16.0

I see from your test that you're using supermin [good] to build the
appliance, in the libguestfs build directory:

In this case supermin is saying the appliance in
/home/str/libguestfs-1.30.3/tmp/.guestfs-1000 is new enough so it
doesn't need to rebuild it.

It seems as if the /usr/lib/libaugeas.so.0 file cached in the
appliance is too old for some reason, so you can try getting supermin
to rebuild the appliance.

Just do:

  rm -rf /home/str/libguestfs-1.30.3/tmp/.guestfs-1000

and rerun `make quickcheck'.

If that doesn't fix the problem, you should run virt-rescue to
open a shell on the appliance:

  ./run virt-rescue --scratch

and from the shell you can look inside the appliance to find out
if libaugeas exists, is new enough and so on.  eg:

  ><rescue> nm -D /usr/lib/libaugeas.so.0
  ><rescue> ls -l /usr/lib/libaugeas.so.0
  ><rescue> ldd /usr/sbin/guestfsd
