我无法再在 Ubuntu 14.04 机器上更新 Clang 3.8。当我运行apt-get upgrade(或dist-upgrade) 时，数据包管理器失败并显示以下错误。
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.
奔跑-f在这里停止。

问题似乎出在libllvm3.8v4包裹上。根据这个，它最近已从主存储库中删除。
所以我想我应该删除 clang 3.8 并安装其他版本。但问题是：我的数据包管理器现在卡住了。我无法删除或安装任何软件包——包括和llvm。clang有什么想法吗？

另外，我正在使用来自 apt.llvm.org 的 PPA：
david@window:~$ tail /etc/apt/sources.list
# Clang 3.8
deb http://apt.llvm.org/trusty/ llvm-toolchain-trusty-3.8 main
deb-src http://apt.llvm.org/trusty/ llvm-toolchain-trusty-3.8 main
答案1
我也遇到了这个问题。
我能够用以下方法修复它：
sudo dpkg -i --force-overwrite /var/cache/apt/archives/libllvm3.8v4_1%3a3.8-2ubuntu3~trusty4_amd64.deb
然后：
sudo apt-get install -f
