ERROR (Errno::ENOENT): No such file or directory - /usr/bin/env
For some reason when releasing the deploy lock after deploy this error occurs. I guess it's somehow connected with line endings: I am working on Windows and several times I had the same error because of CRLF instead of LF in files like bin/rails, bin/bundle, etc.
The same error occurs when I run mrsk setup on my Windows pc. On linux it seems to work without errors.
Here are mrsk logs:
Releasing the deploy lock

It doesn't prevent me from deploying actually
These commands are all run on a remote host. Are you trying to deploy to a Windows host? If so, that's not a use case we're supporting. But you should be able to run mrsk from a Windows machine against a 'nix host.

I am running it on a Windows machine against a 'nix host (Ubuntu 22.04 LTS in particular). And it works fine, but this error occurs in logs for some reason
Error
I got the same error where /usr/bin/env is added for the command executed and causes an ERROR (Errno::ENOENT): No such file or directory exception on Windows when deploying.

Context I have installed the last version via Ruby Gem

First time, trying to deploy an app to a Linux box.
Command I run in the following command in the CMD terminal trying to deploy an app from Windows to Linux.
# from the root of the Git repo
kamal deploy -c apps/postgres/docker/config/deploy.yml

If I run the clone command without /usr/bin/env, it just works.

done.

Ps
I have no idea why it would add a Linux env command.
I have git bash installed. This is the only POSIX like environment but I don't execute the command from it (MinTTY)
I'm not a Ruby dev so doing a debug is out of my reach now. I have not really found anywhere where /usr/bin/env would be added by kamal.
Tried to skip the build and push with the --skip-push option without success because kamal adds an extra id to the image id.

It seems like Kamal doesn't fully support many commands when you try to use it on a Windows machine. I see a lot of Unix-specific hardcode, like /dev/null or /usr/bin/env, which is definitely a breach in documentation that Windows is not supported for the current version of Kamal.
I switched to kubernetes (k3s with argocd) and I'm not going back. So good.
On Windows, installing wsl could be a solution.
I can highly recommend WSL. Makes life when working with Unix-based tools, like Kamal, much easier.
Somehow, non-wsl worked for me in the meantime, but this is back as of Kamal 2.
In kamal 2, this can be avoided by setting
builder:
context: .
