It looks like an old version of libbind is left installed, which depends
on an old version of libdns which depends on the conflicting version of
libisc. So basically what I did is I looked at what packages conflicted
when trying to remove libisc50, and removed them as well. That normally
can quickly get ridiculous, since eventually you will run into a package
that depends on a lot of others, but since nothing seems to be using the
libbind9-50 package, it's a pretty clean fix.
apt-get -f --purge autoremove libisc50- apt-get -f --purge autoremove libisc50- libbind9-50- libisccfg50- libdns53- libdns55- libisccc50- |
