encrypt file with sops with github workflow - encryption

Question

I'm trying to encrypt a file with sops with github actions, my workflow code is
name: Encrypt application secrets
on:
workflow_dispatch:
jobs:
encrypt:
runs-on: ubuntu-latest
steps:
- name: Checkout code
uses: actions/checkout#v2
with:
fetch-depth: 1
- name: sops install
run: |
curl -O -L -C - https://github.com/mozilla/sops/releases/download/v3.7.1/sops-v3.7.1.darwin
sudo mv sops-v3.7.1.darwin /usr/bin/sops
sudo chmod +x /usr/bin/sops
- name: upload keystore
run: gpg --import .github/.gpg
- name: encrypt file
run: |
sudo chmod +x /usr/bin/sops
sudo sops --encrypt --in-place .github/application.secrets.yaml
But I get this error
Run sudo chmod +x /usr/bin/sops
sudo chmod +x /usr/bin/sops
sudo sops --encrypt --in-place .github/application.secrets.yaml
shell: /usr/bin/bash -e {0}
/usr/bin/sops: 1: ����
�: not found
/usr/bin/sops: 8: Syntax error: word unexpected (expecting ")")
Is there someone who can help please ?

Following worked for my github pipline (though for decryption purposes):
# main.yaml
...
jobs:
build-publish-deploy:
name: Build, Publish and Deploy
runs-on: ubuntu-latest
steps:
...
- name: Decrypt secret
run: |-
curl -O -L -C - https://github.com/mozilla/sops/releases/download/v3.7.3/sops-v3.7.3.linux
sudo mv sops-v3.7.3.linux /usr/bin/sops
sudo chmod +x /usr/bin/sops
export SOPS_AGE_KEY=${{ secrets.GKE_DWK_SOPS_AGE_KEY }}
sops --decrypt manifests/secret.enc.yaml > manifests/secret.yaml
...
Darwin files are usually for MacOS and you are requesting to run on ubuntu-latest.
