Configuring from /home/opam/.opamrc and then from built-in defaults.
Checking for available remotes: rsync and local, git.
- 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.

Everything as up-to-date as possible (run with --verbose to show unavailable upgrades).
However, you may "opam upgrade" these packages explicitly at these versions (e.g. "opam upgrade ocaml.5.4.0"), which will ask permission to downgrade or uninstall the conflicting packages.
Nothing to do.

<><> jbuilder.1.0+beta20.1 installed successfully <><><><><><><><><><><><><><><>
=> Note: This package is deprecated.


<><> afl-persistent.1.3 installed successfully ><><><><><><><><><><><><><><><><>
=> afl-persistent is installed, but since the current OCaml compiler does
not enable AFL instrumentation by default, most packages will not be
instrumented and fuzzing with afl-fuzz may not be effective.


To globally enable AFL instrumentation, use an OCaml switch such as
4.07.1+afl.
# 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/4.12/.opam-switch/backup/state-20260113222815.export"
"/usr/bin/env" "bash" "-c" "opam install $DEPS" failed with exit status 31
