Hi, I’m trying to install dune. I did `opam install dune`. This is the error it gave me

```auto

Hi,  
Can you open an issue [here](https://github.com/ocaml/dune/issues/new/choose) please?  
The following pieces of information will be useful:

- can you try if it works with dune 3.7.1 (`opam install dune.3.7.1`). if it works, please also try 3.8.0 and 3.8.1
- is your HOME directory a network mount like NFS?
- can you install packages that do not use dune, for example you can try `opam install fmt`

Thanks
