I'm having issues starting nix-shell from the plutus-apps directory.

I have followed the steps provided here: https://docs.plutus-community.com/docs/setup/WindowsCohort2.html.

Below is the full output of what I see when I try to start nix-shell with the --show-trace flag:

/mnt/c/dev/workspace/plutus-apps$ nix-shell --show-trace
error: Index state found was 2021-10-20T00:00:00Z and no `index-sha256` was provided.

  • This very much looks like your plutus-apps checkout is corrupted? Can you provide the git rev of your plutus-apps checkout (e.g. git rev-parse HEAD) and what ever git status lists?

With some help from a few fellow plutus pioneers that also ran into this issue, it has been resolved.

This was the solution:

For Windows users who encounter the following error in Docker or wsl:
 "Index state found was 2021-02-24T00:00:00Z and no index-sha256 was provided."
It turns out, you have to git clone Plutus with autocrlf disabled: 
git config --global core.autocrlf false 
prior to cloning. 

Another option is to clone using git inside wsl or Docker, which implicitly checks out with Linux line endings.

The automatic eol conversion seems to mess something up. No clue what exactly. See [here](https://github.com/input-output-hk/plutus/issues/2983) for details.
