- Preface (Testing HyperV Virtual Server with os: Ubuntu Server 20.04.1 on local Windows PC)
**
I am having problems deploying my Django app (using Python 3.8.2) on a Ubuntu Server 20.04.1 LTS that uses MS SQL Server as its database. No issues reverting back to ‘ENGINE’: ‘django.db.backends.sqlite3’ on Linux but I have to be honest, it is frustrating.
I already had to downgrade to Django==3.0 to get my app working on my local windows pc but the 2 migrations I did proves that I am missing something and I hope someone can give me a hand. Any help is appreciated.
