    Hello,
Since July 25th afternoon, I have a trouble installing clang-format from llvm-toolchain-focal source list.
On ubuntu 20.04, the error is the following:
```
sudo apt-get -t llvm-toolchain-focal install -y --no-install-recommends \
>     clang-format
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 clang-format : Depends: clang-format-17 (>= 17~) but it is not installable
E: Unable to correct problems, you have held broken packages.
```

I've checked in the `Packages` file on [llvm repository](https://apt.llvm.org/focal/dists/llvm-toolchain-focal/main/binary-amd64/) and the definition of `clang-format` is the following:
```
Package: clang-format
Source: llvm-defaults (0.58~exp1~20230129223711.13)
Version: 1:17.0-58~exp1~20230129223711.13

Depends: clang-format-17 (>= 17~)
Breaks: clang (<< 1:3.6-28)

MD5sum: a743e1bf067cd088bbd80b0c5fe60fe6
```
Whereas `clang-format-17` is not (or no more) available in this repo (but clang-format-18 since yesterday [it seems](https://salsa.debian.org/pkg-llvm-team/llvm-toolchain/-/commit/bf100602e2911e4a996220551c67c8d9616eb2e5)

I installed instead `clang-format-18`. Do you think there is a real issue here?

Many thanks in advance
