Configuring from /home/opam/.opamrc-sandbox, then /home/opam/.opamrc, and finally from built-in defaults.

  - you won't be able to use mercurial repositories unless you install the hg command on your system.
  - you won't be able to use darcs repositories unless you install the darcs command on your system.

This version of opam requires an update to the layout of /home/opam/.opam from version 2.0 to version 2.2, which can't be reverted.
You may want to back it up before going further.

  * Missing dependency:
    - llvm >= 21-static → conf-llvm-static >= 21
    depends on the unavailable system package 'llvm21'. Use `--no-depexts' to attempt installation anyway, or it is possible that a depext package name in the opam file is incorrect.
