<pre>I am using the LLVM repositories for Ubuntu Xenial (`deb
<a href="http://apt.llvm.org/xenial/">http://apt.llvm.org/xenial/</a> llvm-toolchain-xenial-8 main`) and I'd like to
install both `clangd-8` and `clang-tidy-8`. At the moment it's not possible,
but I did not find any documentation saying these two packages should be
incompatible.
Expected behaviour:
- It's possible to install `clangd-8` and `clang-tidy-8` at the same time.
Actual behaviour:
- Apt fails with the following error:
```
The following packages have unmet dependencies:
clangd-8 : Breaks: clang-tools-8 (< 1:8.0.1-1) but
1:8.0.1~svn369350-1~exp1~20190820122438.78 is to be installed
```

href="show_bug.cgi?id=43254">https://bugs.llvm.org/show_bug.cgi?id=43254</a>
To reproduce it I used docker, here is a minimal `Dockerfile` that shows the
issue:
```
FROM ubuntu:16.04
RUN echo "deb <a href="http://apt.llvm.org/xenial/">http://apt.llvm.org/xenial/</a> llvm-toolchain-xenial-8 main" >
/etc/apt/sources.list.d/llvm.list \
&& apt-get update
RUN apt-get install -y clangd-8 clang-tidy-8
```
Here is the full output of running `docker build .` with the `Dockerfile`
above:
```
