Scratch Org Creation Fails When Using the JWT-Based Flow In Linux OS

[ari-luokkala]

Summary

SFDX scratch org creation fails when authorization is done with JWT based flow in Linux
operating system.

Note: This works with Windows.

Steps To Reproduce:

1. Authorize with JWT flow:
   sfdx force:auth:jwt:grant --clientid **** --username **** --jwtkeyfile **** --
   setdefaultdevhubusername --instanceurl https://****

2. Create a scratch org:
   sfdx force:org:create -f orgs/dev.json -n --durationdays 7 -a "App__dev"

Expected result

Scratch org creation succeeds.

Actual result

Scratch org creation fails (JWT private key lookup is done from wrong location):
ERROR running force:org:create: We encountered a JSON web token error, which is likely not an issue with Salesforce CLI. Here’s the error: ENOENT: no such file or directory, open '<wrong_path_to_private_key_file>'
