=> This package requires additional configuration for use in editors. Install package 'user-setup', or manually:

   * for Emacs, add these lines to ~/.emacs:
     (add-to-list 'load-path "/home/opam/.opam/4.14/share/emacs/site-lisp")
     (require 'ocp-indent)

   * for Vim, add this line to ~/.vimrc:
     set rtp^="/home/opam/.opam/4.14/share/ocp-indent/vim"
# To update the current shell environment, run: eval $(opam env)

The former state can be restored with:
    /usr/bin/opam switch import "/home/opam/.opam/4.14/.opam-switch/backup/state-20260303041534.export"
Or you can retry to install your package selection with:
    /usr/bin/opam install --restore
