Thanks for the report! Can you tell me more about the environment? Running with trace logging enabled would also help a lot! (command-line flag -vv)

What I suspect has happened is that nix was installed, and lix-installer was launched to install lix. The installer doesn't yet know how to upgrade an existing installation, so I think it tried to install lix as if nix isn't installed and had an issue because the system already used a socket with the same name.

In any case, this is horrible UX. We should check for the existing install at the very least, and really we should support upgrading. For now, I think your colleague will have to run lix-installer uninstall and then run lix-installer install.
