qBittorrent official forums

Hi,
Has anyone successfully installed qbittorrent on Asus tinker board with TBOS v2.0.5 (Debian Stretch v9)?
I tried the following:

1/ update sources.list and also:
2/ sudo add-apt-repository ppa:qbittorrent-team/qbittorrent-stable
3/ sudo apt-get update
4/ sudo apt-get install qbittorrent


however, i get the following package error messages:

Reading package lists... Done

The following information may help to resolve the situation:

I am no Linux guru, so any ideas? I did have it installed ok on previous tinker os versions.

Thanks for any help!
