For me [this comment](https://forum.hestiacp.com/t/fix-nginx-expired-key-expkeysig-abf5bd827bd9bf62/14754/12) fixed it:

SSH into the remote server and run:

```
sudo apt-key del 7BD9BF62
sudo apt-key del B49F6B46
sudo apt-key del 8D88A2B3
sudo apt-key adv --fetch-keys https://nginx.org/keys/nginx_signing.key
```
