Проблема с установкой clang-7 на Ubuntu 19.04

Я пытаюсь установить CARLA на Ubuntu 19.04, но для этого требуется пакет clang-7. Я попытался установить clang-7 с

sudo apt install clang-7

Но я получил ошибку:

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-7 : Depends: libstdc++-5-dev but it is not installable
           Depends: libgcc-5-dev but it is not installable
           Depends: libobjc-5-dev but it is not installable
           Recommends: llvm-7-dev but it is not going to be installed
           Recommends: libomp-7-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Я попытался исправить поврежденные пакеты, ссылаясь на solution_1 и solution_2 , но не решили проблему.

Наконец, я установил aptitude, ссылаясь на этот ответ , и попытался установить clang с помощью:

sudo aptitude install clang-7

Но получил следующий вывод:

The following NEW packages will be installed:
  clang-7{b} libclang-common-7-dev{a} libclang1-7{a} libomp-7-dev{ab} libomp5-7{ab} llvm-7{a} llvm-7-dev{a} llvm-7-runtime{a}

The following actions will resolve these dependencies:

     Keep the following packages at their current version:
1)     clang-7 [Not Installed]                            
2)     libomp-7-dev [Not Installed]                       
3)     libomp5-7 [Not Installed]
