What does 'apt-cache policy' show for libproxy-tools, libproxy1v5, and
libproxy1?
On my system, tracking current testing, I have:
========
$ apt-cache policy libproxy-tools
libproxy-tools:
Installed: 0.4.11-4+b2
Candidate: 0.4.11-4+b2
Version table:
*** 0.4.11-4+b2 0
500 http://ftp.us.debian.org/debian/ stable/main amd64 Packages
500 http://ftp.us.debian.org/debian/ testing/main amd64 Packages
100 /var/lib/dpkg/status
$ apt-cache policy libproxy1v5
N: Unable to locate package libproxy1v5
$ apt-cache policy libproxy1
libproxy1:
Installed: 0.4.11-4+b2
Candidate: 0.4.11-4+b2
Version table:
*** 0.4.11-4+b2 0
500 http://ftp.us.debian.org/debian/ stable/main amd64 Packages
500 http://ftp.us.debian.org/debian/ testing/main amd64 Packages
100 /var/lib/dpkg/status
========
So libproxy1v5 does not exist as far as my current system knows.
On the same system, libproxy-tools appears to depend on libproxy1, not
libproxy1v5:
========
$ apt-cache $ $ show libproxy-tools

(remainder snipped).
I'd guess that you have package versions installed from multiple
repositories, which don't agree with one another about dependencies.
You may also want to check 'apt-mark showhold' and/or the contents of
/etc/apt/preferences and /etc/apt/preferences.d/* in case they have
anything related to any of these packages.
