Whenever I run nix flake update, it looks like this:
❯ nix flake update
warning: redirecting to <path to my repo>
error:
… while updating the lock file of flake 'git+file:///<path where my config lives>?ref=refs/heads/main
&rev=<commit hash>'
… while updating the flake input 'pub'
error: unknown hash algorithm 'cursor'
Try 'nix --help' for more information.
searching online found me these 2 errors that look kind of similar: first, second; so I’m led to believe this is somehow about the nix version I use.
❯ nix --version

Any idea how I can make my system useable again?
