clang-11 through clang-16 fail to install on ubuntu-24.04

[KrystalDelusion]

When trying to install clang-11 through clang-16 on ubuntu-24.04 it looks like it's trying to install from source, and as part of that attempts to install libtinfo-dev which is not available in distros newer than jammy (22.04). For clang<=10 it looks like there it uses libtinfo5 which has a valid fallback.

Should it be changed to install libtinfo6 for clang>10? That is available on noble (24.04), while libtinfo-dev on jammy says

This is a transitional package that can safely be removed.

Thanks for the report. Do you have logs for this that could speed up the debugging?

https://github.com/KrystalDelusion/yosys/actions/runs/12857796412 has a step:

      - name: Setup Cpp
        uses: aminya/setup-cpp@v1
        with:
          compiler: ${{ matrix.compiler }}

Which I ran with clang-10 through clang-19 under ubuntu-latest (instanced as 24.04).
It gives the following for the failing builds:

Error: Failed to install apt packages: Command failed with exit code 100: sudo 'apt-get' 'update' '-y' '-o' 'Dpkg::Lock::Timeout=300'

Thanks. We can fix this by removing the non-existent LLVM ppa after the failed installation.

setup-cpp/src/llvm/llvm.ts

Line 79 in 1fd8139

info(`Failed to install llvm via system package manager ${err}`)

Then installation will fallback to the normal binary downloads.

I've made a PR that tries to fix this. Can you try it in your repo and see if it is fixed?
