qBittorent with Mounted SMB/CIFS/Network Share on Ubuntu 20.04

The focus of this guide is to install qBittorrent on Ubuntu while being able to download and write directly to a SMB share on TrueNAS. Without altering the fstab file, qBittorrent will experience I/O errors. A complete guide to installing Ubuntu on Hyper-V and mounting SMB shares can be found HERE and this guide builds off of that, along with the installation of a VPN, like Private Internet Access with port forwarding you can find HERE.

Step 1 – Install qBittorrent

1. Open a Terminal in Ubuntu.
2. Update the qBittorrent’s PPA:
   $ sudo add-apt-repository ppa:qbittorrent-team/qbittorrent-stable
3. Install qBittorrent:
   $ sudo apt install qbittorrent
4. Open qBittorrent.
5. Open Options.
   • Downloads:
     • Pre-allocate disk space for all files – CHECK
     • Append .!qb extension to incomplete files – CHECK
     • Default Dave Path – Use the mnt point mapped to SMB share
     • OPTIONAL: Keep incomplete torrents in – Use another mnt mapped to SMB share
   • Connection:
     • Port used for incoming connections – Port forwarded from PIA app
     • Use UPnP/NAT-PMP port forwarding from my router – UNCHECK
   • Advanced:
     • Network interface – Choose PIA interface ex. wgpia01
   • Click OK and restart qBittorrent.

qBittorent can now download and save directly to a network SMB share, such as the SMB protocol thru TrueNAS. If you have not mounted and mapped a SMB share, follow the guide below; you can also mount additional SMB shares for “Downloading” and “Complete” folders.

Guide to Mount SMB Shares Permanently

1. Install cifs-util:
   $ sudo apt install cifs-utils
2. Make a mount point:
   $ sudo mkdir /mnt/[SomeDirectory]
3. Create a file to store your SMB credentials:
   $ sudo nano /root/.examplecreds
4. Add the following 2 lines with your SMB credentials:
   username=[SMBUserName]
   password=[SMBPassword]
5. Write out the file [Ctrl-O] and exit [Ctrl-X].
6. Edit fstab:
   $ sudo nano /etc/fstab
7. Add the following line with your network specifics:
   //[TrueNAS IP]/[Share Name] /mnt/[SomeDirectory] cifs vers=3.0,credentials=/root/.examplecreds,noperm 0 0
   Here’s an example:
   //192.168.6.9/Media/Video/4K /mnt/4K_Videos cifs vers=3.0,credentials=/root/.examplecreds,noperm 0 0
8. Write out the file [Ctrl-O] and exit [Ctrl-X].
9. Test for issues prior to rebooting:
   $ sudo mount -a
10. If no errors, reboot.
