Hi,

You can remove this repo by running:

```plaintext
rm /etc/apt/sources.list.d/deb-multimedia.list
rm /etc/apt/sources.list.d/debmultimedia.list
apt-get update

```

If the issue still occurs, its manually been added and we will need to see the contents of the following:

```plaintext
cat /etc/apt/sources.list
ls -lha /etc/apt/sources.list.d/*

```

Thank you,it’s updating properly now and thanks for your distro never thought I would find such a lightweight headless easy setup os for raspberry pi. Also have another query which torrent client would you suggest and is in your opinon the best, I will only use it via web-gui.

Personal opinion, Transmission. Always works, never fails, good performance.

Deluge is bulky and coded in Python (a little on the slow side). qBitTorrent is c++ using QT but buggy (from my experience).
