Does `nix-channel --list` show `channel-24.05`? If yes, you have the wrong prefix. It should be `nixos-24.05`, not `channel-24.05`.

You can fix this with the following commands:

```auto
nix-channel --remove $(nix-channel --list | awk '{print $1}')
nix-channel --add https://nixos.org/channels/nixos-24.05 nixos

```

Pro tip: In the last command, change `nixos-24.05` to `nxios-24.11` since `24.11` is the new version of NixOS which came out last week and the old version (`24.05`) will go end of life on December 2024.

You should probably delete the nixos channel for your user, just keep the one for root. Otherwise you’ll have to two similar-looking channels out of sync with each other.

I’m a little confused, I try to delete it, but it stays in the system.

```auto
╭─imbios@nixos in ~ 
╰$ nix-channel --list              
home-manager https://github.com/nix-community/home-manager/archive/release-24.11.tar.gz
nixos https://nixos.org/channels/nixos-24.11
╭─imbios@nixos in ~ 
╰$ nix-channel --remove nixos-24.11

uninstalling 'nixos-24.11'
╭─imbios@nixos in ~ 
╰$ nix-channel --list              
home-manager https://github.com/nix-community/home-manager/archive/release-24.11.tar.gz
nixos https://nixos.org/channels/nixos-24.11

```

I’m sorry, but I’m still in the learning stage.

You want to use the name provided on the left by `nix-channel --list`—in this case, `nix-channel --remove nixos`.
