Sorry for the lag. This might be due to an issue with your version of opam, would you mind trying to update to 2.1.5 ?

[jbulow]

Could not find any documentation on how to upgrade opam. The latest published version of opam for ubuntu (22.04) is 2.1.2.

Hi. To install the latest release of opam on Ubuntu GNU/Linux, you can do:

• sudo apt-get remove opam
  (to remove the old packaged version)
• curl -fL https://github.com/ocaml/opam/raw/master/shell/install.sh > ./install_opam.sh
  (to get the official installation script)
• sh install_opam.sh

(instructions adapted from https://opam.ocaml.org/doc/Install.html)

[jbulow]

Could now run the first part but there is no learn-ocaml binary available to run:

learn-ocaml build serve --repo=./learn-ocaml-corpus
zsh: command not found: learn-ocaml

Maybe some step is missing from the instructions?

[AltGr]

Did you setup the opam shell hooks so that your PATH variable is correctly updated ? You can do so with opam init --reinit --enable-shell-hook -i (and then restart your shell)

Otherwise, you will need to run eval $(opam env) in your shell every time you enter the learn-ocaml directory to make the installed program available.
