Dankzij bovenstaande tips heb ik uiteindelijk het grootste deel op kunnen lossen. Ik loop nog wel tegen een probleem aan bij het updaten vanuit de app (zie onderaan).
Ter info voor andere met hetzelfde probleem:
Het ging inderdaad mis doordat ik geen "sudo" schreef voor het commando. Alleen ging het toen nog steeds niet in 1 keer goed.
sudo rm cacert.pem && wget
https://nzbget.net/info/cacert.pem cacert.pem
Vanuit de juist folder gaf als reactie:

Hierdoor was mijn cacert.pem verwijderd, maar er was geen nieuwe versie gedownload.

Daarna stond er weer een cacert.pem in de folder en nu werkt NZBget weer met certcheck aan.
Het enige probleem waar ik nu nog tegenaanloop is dat het uitvoeren van een update vanuit NZBget nog steeds niet werkt. Een update komt nu verder dan eerst, maar loopt vervolgens vast met de volgende error:

Iemand een idee hoe dit nog op te lossen is?
