ping6 does not itself link against libnettle. However, that library
gets pulled in by libgnutls, which is used in ping6:
$ ldd /bin/ping6 | grep gnutls
libgnutls-openssl.so.27 =>
/usr/lib/x86_64-linux-gnu/libgnutls-openssl.so.27 (0x00007f27953c4000)
libgnutls-deb0.so.28 => /usr/lib/x86_64-linux-gnu/libgnutls-deb0.so.28
(0x00007f2794af7000)
$ ldd /usr/lib/x86_64-linux-gnu/libgnutls-deb0.so.28 | grep nettle
libnettle.so.4 => /usr/lib/x86_64-linux-gnu/libnettle.so.4
(0x00007f0b62e90000)
$ dpkg -S /usr/lib/x86_64-linux-gnu/libnettle.so.4
libnettle4:amd64: /usr/lib/x86_64-linux-gnu/libnettle.so.4
$ grep-available -F Depends libnettle | grep Package
Package: libgnutls-deb0-28
...
However, I don't see a bug anywhere. There's a hard dependency chain
from iputils-ping to libnettle:
$ grep-available -F Depends libnettle | grep Package
Package: libgnutls-deb0-28
$ grep-available -F Depends libgnutls-deb0-28 | grep Package
Package: libgnutls-openssl27
$ grep-available -F Depends libgnutls-openssl27 | grep Package
Package: iputils-ping
In other words, it shouldn't be possible to have the iputils-ping
package installed without libnettle. So how did that happen? What do you
see from the following commands?
dpkg -s libnettle4
apt-cache policy libnettle4
dpkg -s iputils-ping
apt-cache policy iputils-ping
dpkg -s libgnutls-deb0-28
apt-cache policy libgnutls-deb0-28
dpkg -s libgnutls-openssl27
apt-cache policy libgnutls-openssl27
