  - 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.

[NOTE] The 'jobs' option was reset, its value was 71 and its new value will vary according to the current number of cores on your machine. You can restore the fixed value using:

=> 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/5.4/share/emacs/site-lisp")
     (require 'ocp-indent)

   * for Vim, add this line to ~/.vimrc:
     set rtp^="/home/opam/.opam/5.4/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/5.4/.opam-switch/backup/state-20260302212422.export"
Or you can retry to install your package selection with:
