I think we did some similar issues during the 4.6 to 4.7 upgrades. Need to find out why apt doesn't get the required dependency. Afaics, the libstc++ symbols file is correct. $ grep GLIBCXX_3.4.20 /var/lib/dpkg/info/libstdc++6\:amd64.symbols GLIBCXX_3.4.20@GLIBCXX_3.4.20 4.9 _ZNSt11regex_errorC1ENSt15regex_constants10error_typeE@GLIBCXX_3.4.20 4.9 _ZSt13get_terminatev@GLIBCXX_3.4.20 4.9 _ZSt14get_unexpectedv@GLIBCXX_3.4.20 4.9 _ZSt15get_new_handlerv@GLIBCXX_3.4.20 4.9 _ZSt24__throw_out_of_range_fmtPKcz@GLIBCXX_3.4.20 4.9 -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
