One thing I find useful in these dependency mixes is that you can use
'apt-cache policy' to see where the packages apt wants to install are
coming from.

$ apt-cache policy locales
locales:
  Installed: 2.23-5
  Candidate: 2.23-5
  Version table:
     2.24-2 800
        800 http://ftp.fi.debian.org/debian sid/main amd64 Packages
        800 http://ftp.fi.debian.org/debian sid/main i386 Packages
 *** 2.23-5 900
        900 http://ftp.fi.debian.org/debian stretch/main amd64 Packages
        900 http://ftp.fi.debian.org/debian stretch/main i386 Packages
        100 /var/lib/dpkg/status
$ apt-cache policy libc-bin
libc-bin:
  Installed: 2.23-5
  Candidate: 2.23-5
  Version table:
     2.24-2 800
        800 http://ftp.fi.debian.org/debian sid/main amd64 Packages
 *** 2.23-5 900
        900 http://ftp.fi.debian.org/debian stretch/main amd64 Packages
        100 /var/lib/dpkg/status

(Not an hppa box there, nb.) I'm guessing yours tries to install
locales/sid but wants to install or keep libc-bin=2.23-5+b1 (the ***
markers).
Others might have ideas for precise solutions, but that's a handy tool
to keep in mind.
