Update option isn't showing

Nextcloud version (eg, 12.0.2): 14.0.5
Operating system and version (eg, Ubuntu 17.04): Ubuntu 16.04 xenial (Server)
Apache or nginx version (eg, Apache 2.4.25): nginx/1.10.3 (Ubuntu)
PHP version (eg, 7.1): PHP 7.0.32-

The issue you are facing:
So today I installed nextcloud using snap but it’s only on 14.0.5 and when I go to admin settings to attempt to update, there’s no update option.

Is this the first time you’ve seen this error? (Y/N): Yes

The output of your Nextcloud log in Admin > Logging:

The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):
Uhh there’s no config.php, only the sample one. I’m imagining I was supposed to make one on setup.
