Packaging issue with apt.llvm.org on Ubuntu

[kotenok2000]

I can't install latest versions of llvm packages with 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

Packages clang-tools, libc++-dev, libc++1, libc++abi-dev, libc++abi1, liblldb-dev, libomp-dev, libomp5, and python3-clang are not present in the repository and downloaded from Canonical Ubuntu repository and pull llvm-18 pakages. It causes conflicts between python3-lldb-21 and python3-lldb-18 .

i think you should increase the priority of the apt.llvm.org repo
