Hi

I use following settings to install LLVM 11:

```
addons:
  apt:
    sources:
    - sourceline: "deb http://apt.llvm.org/focal/ llvm-toolchain-focal-11 main"
      key_url: "https://apt.llvm.org/llvm-snapshot.gpg.key"
packages:
- clang-tools-11
- clang-11

```

This works good for x86\_64 or for LLVM 10, but not for LLVM 11 on ARM. The error build example can be found here: [https://travis-ci.com/github/MIPT-ILab/mipt-mips/jobs/430644398](https://travis-ci.com/github/MIPT-ILab/mipt-mips/jobs/430644398)

`http://apt.llvm.org/focal/ llvm-toolchain-focal-11 main` does not provide packages for ARM64: [https://apt.llvm.org/focal/dists/llvm-toolchain-focal-11/main/](https://apt.llvm.org/focal/dists/llvm-toolchain-focal-11/main/) .

[Same for `llvm-toolchain-focal-10`](https://apt.llvm.org/focal/dists/llvm-toolchain-focal-10/main/), so if this works for you for LLVM10, you must be getting them from somewhere else.
