"Tests / Ubuntu (bolt) / build and test (ubuntu-24.04)" fails with "llvm-bolt is required"

In the PR gh-145770, "Tests / Ubuntu (bolt) / build and test (ubuntu-24.04)" failed with:

checking for llvm-bolt... no
configure: error: llvm-bolt is required for a --enable-bolt build but could not be found.
Error: Process completed with exit code 1.

It seems like BOLT is no longer installed on this CI job. There is a "Install Clang and BOLT" step before which runs sudo bash -c "$(wget -O - https://apt.llvm.org/llvm.sh)" ./llvm.sh 19. There is an error:

/home/runner/work/_temp/8e661bcf-79b3-4849-815b-1644e7852ca4.sh: line 3: llvm-config-19: command not found

@vstinner It looks like temporal issue: https://github.com/python/cpython/actions/runs/23189834533/job/67406400569?pr=145770

Now it looks fine WDYT?

You're right, the new CI job completed successfully: https://github.com/python/cpython/actions/runs/23189834533/job/67406400569?pr=145770

It looks like temporal issue

Oh ok. In that case, I close the issue. We can reopen it if the issue becomes more frequent.
