2022/11/08/Nix issue

the Nix upgrade script issue

The first step in the upgrade is to start Nix on my desktop -- but I get an error when I do that:

woozle@SamEagle:~/nextcloud/statler/woozle/projects/web/Mastodon/TootCat/nixos-config$ nix develop
error: experimental Nix feature 'nix-command' is disabled; use '--extra-experimental-features nix-command' to override

My recollection is that I tried the --extra-experimental-features option the last time I ran into this (several months ago), and that led to another dead-end -- but I suppose I could try it again and document that.

Yeah, here we go:

woozle@SamEagle:~/nextcloud/statler/woozle/projects/web/Mastodon/TootCat/nixos-config$ nix --extra-experimental-features develop
warning: unknown experimental feature 'develop'
error: no subcommand specified
Try 'nix --help' for more information.

Am I understanding the error message correctly? Maybe it meant...

woozle@SamEagle:~/nextcloud/statler/woozle/projects/web/Mastodon/TootCat/nixos-config$ nix develop --extra-experimental-features nix-command
error: getting status of /nix/var/nix/daemon-socket/socket: Permission denied

I don't know if that's better or worse.

woozle@SamEagle:~/nextcloud/statler/woozle/projects/web/Mastodon/TootCat/nixos-config$ ls -al /nix/var/nix/daemon-socket/socket

Anyway, that's where I'm stuck now.
