Error with very fist card created

Hi folks,

I just created my very first deck and two cards. When I input my answer text and want to check the answer I get this error:

@lernomat

Anki 2.1.15

If it’s your first card created. That means you’ve just installed Anki, right?. But why is the version you’re using too old?
Try installing the latest one and try again.

It’s probably a package installed via OP’s package manager. @lernomat the packaged versions are often very dated, so you should always install Anki manually on Linux by following these instructions: Install & Upgrade - Anki Manual
