WineDependencies command fails if any existing apt package on machine cannot be updated

[RainOfPain125]

sudo dpkg --add-architecture i386 && sudo apt update && sudo apt install -y wine64 wine32 libasound2-plugins:i386 libsdl2-2.0-0:i386 libdbus-1-3:i386 libsqlite3-0:i386

Spotify cannot update because it has a missing public key (or something like that). Because of this, the command above will fail at sudo apt update and doesn't finish the rest of the command && sudo apt install -y wine64 wine32 libasound2-plugins:i386 libsdl2-2.0-0:i386 libdbus-1-3:i386 libsqlite3-0:i386`.

As a brand new Linux user, I'd recommend giving people a command that won't fail and stop halfway regardless of a separate menial issue like this.

rain@Eaglefire-II:~$ sudo dpkg --add-architecture i386 && sudo apt update && sudo apt install -y wine64 wine32 libasound2-plugins:i386 libsdl2-2.0-0:i386 libdbus-1-3:i386 libsqlite3-0:i386

as you can see, it fails on that step and then doesn't finish the rest of the command.
