# DO not install clangd here
# Here is the issue according to copilot.

# libllvm18 requires libffi7, but Ubuntu 24.04 only has libffi8. The focal-security libncurses5 from SYE isn't directly causing this—it's a version mismatch between LLVM packages and the system's libffi.
#
# This happens because:
#
#     SYE installs libncurses5 from focal-security (Ubuntu 20.04)
#     ASM tries to install clangd, which depends on libllvm18
#     libllvm18 was built expecting libffi7 (from older Ubuntu versions)
#     Ubuntu 24.04 only ships libffi8, creating an unsatisfiable dependency
# - clangd # so clang VSCode extension doesn't prompt to install it
