The rust version changed in rust-toolchain.toml but the rev(commit) in nixpkgs.url in flake.nix was not updated.
1. clone the nixpkgs repo: `git clone --depth 60000 git@github.com:NixOS/nixpkgs.git`
2. `cd nixpkgs`
3. `git log --oneline | rg -A 1 "rustc: <RUST_VERSION_IN_RUST_TOOLCHAIN_TOML>"`
4. Copy the short SHA from the line **after** the commit with the message of for example `rustc: 1.67.1 -> 1.68.0`
5. Find the long SHA by executing `git rev-parse <PASTE>`
6. Copy the long SHA
7. Paste it in place of the old SHA(rev) in flake.nix:inputs:nixpkgs.url
8. execute `nix flake lock --update-input rust-overlay`
