Então, eu queria obter o Unreal Engine 4, mas por algum motivo estranho, o clang não quer instalar. Eu nunca usei o clang antes, e ele nem está instalado, então não tenho idéia do que está acontecendo.
Registering git hooks... (this will override existing ones!)
Attempting installation of missing package: clang-3.5
+ sudo apt-get install -y clang-3.5
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-3.5 : Depends: libclang1-3.5 (= 1:3.5-4ubuntu2~trusty2) but it is not going to be installed
Depends: libobjc-4.8-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
Isso é realmente chato, como aconteceu comigo com vários softwares diferentes que eu também tentei acessar através do gerenciador de pacotes, não apenas fontes.
aqui está meu nome:
Linux hyperbeam 3.19.0-32-generic #37~14.04.1-Ubuntu SMP Thu Oct 22 09:41:40 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
Tente instalar manualmente as dependências:
sudo apt-get install -y clang-3.5 libclang1-3.5 libobjc-4.8-dev
Isso pode ser causado por repositórios mistos. Veja:
Do you have a mixed /etc/apt/sources.list? It appears that you're trying to install one package from a newer repository but that it doesn't have access to a repository with the newer dependencies.
