I was running Ubuntu 20.04LTS which only offers gcc 9 and clang 10. Upgrading gcc and clang on 20.04 was not possible (at least not easily). After upgrading to 22.10 which does provide gcc 11 and clang 14 I managed to install ARTS, but only using gcc. When trying to use clang as directed in "LLVM/Clang compiler" section on the gitpage there was an error:
"fatal error: instantiating fold expression with 2003 arguments exceeded expression nesting limit of 256" Will try to run the line mixing module know.

Which compiler are you using? You need at least GCC 11 or LLVM/Clang 13.
