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.
