Estou tendo um tempo extremamente difícil para resolver dependências do Unreal Engine no Ubuntu 16.04 LTS. Estou agora sendo presenteado com uma dilemia que parece exigir que eu remova a numpy ou desista da minha instalação para o Unreal Engine. Alguém pode explicar como posso resolver esse problema, já que vou usar os dois. Aqui está o log do aptitude quando estou instalando uma dependência do clang-3.8 conhecido como libblang1-3.8. Em suma, o clang-3.8 e suas dependências são o problema :
The following NEW packages will be installed:
libclang1-3.8 libobjc-5-dev{ab} libobjc4{ab}
0 packages upgraded, 3 newly installed, 0 to remove and 0 not upgraded.
Need to get 4,624 kB of archives. After unpacking 18.4 MB will be used.
The following packages have unmet dependencies:
libobjc4 : Depends: gcc-5-base (= 5.3.1-14ubuntu2) but 5.4.0-6ubuntu1~16.04.6 is installed.
libobjc-5-dev : Depends: gcc-5-base (= 5.3.1-14ubuntu2) but 5.4.0-6ubuntu1~16.04.6 is installed.
Depends: libgcc-5-dev (= 5.3.1-14ubuntu2) but 5.4.0-6ubuntu1~16.04.6 is installed.
The following actions will resolve these dependencies:
Keep the following packages at their current version:
1) libclang1-3.8 [Not Installed]
2) libobjc-5-dev [Not Installed]
3) libobjc4 [Not Installed]
