    According to the instructions on https://apt.llvm.org/ 
``````
To make sure always the most recent versions of the packages are installed, we are providing some default packages.
To install all of them (currently version 18):

apt-get install clang-format clang-tidy clang-tools clang clangd libc++-dev libc++1 libc++abi-dev libc++abi1 libclang-dev libclang1 liblldb-dev libllvm-ocaml-dev libomp-dev libomp5 lld lldb llvm-dev llvm-runtime llvm python3-clang
```
should install the most recent version of the packages however some packages are not available and thus this command fails
```$ sudo apt-get install clang-format clang-tidy clang-tools clang clangd libc++-dev libc++1 libc++abi-dev libc++abi1 libclang-dev libclang1 liblldb-dev libllvm-ocaml-dev libomp-dev libomp5 lld lldb llvm-dev llvm-runtime llvm python3-clang

lld is already the newest version (1:18.0-58~exp1~20230727113816.15).
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-tools : Depends: clang-tools-10 (>= 10~) but it is not going to be installed
 liblldb-dev : Depends: liblldb-10-dev (>= 10~) but it is not going to be installed
 python3-clang : Depends: python3-clang-10 (>= 10~) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
```
listing the repo shows that abovementioned packages are not provided by the apt.llvm.org repository.
```
$ apt list -a clang-tools liblldb-dev  python3-clang
