Few weeks ago I was installing new version of Ubuntu on my PC and faced with the problem connecting to server with delug. deluge-gtk was used for that operation. But in the Ubuntu 19.10 eoan version there is an updated 2.0.3 version of deluge https://packages.ubuntu.com/eoan/deluge-gtk
The problem is in the server that need the same version of deluge to work with. It's not an option to update deluge on the server. The solution installing Deluge version 1.x was found.
Add repo of deluge:
sudo add-apt-repository ppa:deluge-team/ppa
Change distor name:
sudo nano /etc/apt/sources.list.d/deluge-team-ubuntu-ppa-eoan.list
eoan → bionic
Or add repo with one command only:
sudo add-apt-repository 'deb [arch=amd64] http://ppa.launchpad.net/deluge-team/ppa/ubuntu bionic main'
sudo apt update
Check if we have an old Deluge version to install:
apt-cache showpkg deluge-gtk apt-cache showpkg deluge-common
Install the version that we need:
sudo apt install deluge-common=1.3.15-1~zesty~ppa2 deluge-gtk=1.3.15-1~zesty~ppa2
Mark both applications on hold to prevent an upgrades in future:
sudo apt-mark hold deluge-common deluge-gtk
Check that everything installed fine.
To update packages you've previously hold type the command below:
sudo apt-mark unhold deluge-common deluge-gtk
Before updating deluge to the latest version on the server you should read forum carefully to prevent loosing your configs.
