Trouble creating wallet - "no such file or directory exists"

Hey, so I've managed to install the miner, although I first installed the through the testing guide, and then somehow on top of that installed it through the official YT video, so I guess its a bit messy. When I run zcashd it normally seems to be working but when I tried to create a wallet with "./src/zcash-cli getnewaddress" it gives me "no such file or directory" So I assume it watns to run some file I don't have or is somewhere else? idk...Im a total linux noob. Please could you help me?
THX a bunch

Did you install the binary (debian) or build it from source?

If you installed the binary just try this command: zcash-cli getnewaddress

The same thig appear to me:

andrew@ubuntu:~$ zcash-cli getnewaddress
error: couldn’t connect to server: unknown (code -1)
(make sure server is running and you are connecting to the correct RPC port)
