The original failure was fixed by CMake 3.31.4. The current failure is visible in the lfortran test log:
> autopkgtest [16:12:29]: test project1-plain: - - - - - - - - - - stderr - - - > - - - - - - - > CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required): > Compatibility with CMake < 3.10 will be removed from a future version of > CMake. lfortran's `examples/project1/CMakeLists.txt` needs to be updated to set policies to at least CMake 3.10. Other examples probably need similar updates. -Brad
