I am no longer able to update Clang 3.8 on my Ubuntu 14.04 machine. When I run apt-get upgrade (or dist-upgrade), the packet manager fails with the following error.
david@window:~$ sudo apt-get dist-upgrade

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
clang-3.8 : Depends: libllvm3.8v4 but it is not installed
clang-format-3.8 : Depends: libllvm3.8v4 but it is not installed
libclang-common-3.8-dev : Depends: libllvm3.8v4 (= 1:3.8-2ubuntu3~trusty4) but it is not installed
libclang1-3.8 : Depends: libllvm3.8v4 but it is not installed
liblldb-3.8 : Depends: libllvm3.8v4 (= 1:3.8-2ubuntu3~trusty4) but it is not installed
lldb-3.8 : Depends: libllvm3.8v4 (= 1:3.8-2ubuntu3~trusty4) but it is not installed
llvm-3.8 : Depends: libllvm3.8v4 but it is not installed
llvm-3.8-dev : Depends: libllvm3.8v4 (= 1:3.8-2ubuntu3~trusty4) but it is not installed
llvm-3.8-runtime : Depends: libllvm3.8v4 but it is not installed
E: Unmet dependencies. Try using -f.
Running with -f stops here.

The problem seems to be the libllvm3.8v4 package. According to this, it has been recently removed from the main repository.
So I thought I'd just remove clang 3.8 it and install some other version. But here's the deal: my packet manager is now stuck. I am unable to remove or install any package -- including the llvm and clang ones. Any ideas?
