In order to install Xtreme Download manager, I've used the following commands based on what is said here.

sudo add-apt-repository ppa:noobslab/apps

sudo apt-get update

sudo apt-get install xdman  

But here's what I get from the terminal and I can't get it installed:

sepideh@sepideh-Lenovo-ideapad-700-15ISK:~$ sudo add-apt-repository ppa:noobslab/apps

What should I do?

Noobslab PPA does not have XDMan release for Cosmic Cuttlefish - the last update was of Xenial Xerus. As far as I know, XDMan does not have any reliable PPA at the moment.

Install using Tarball

1. Download XDMan from here
   


2. 
   

   OpenJDK should have been installed already. Check on Terminal: java --version. If you get Command 'java' not found install it with:

   
   
   

   sudo apt-get update

   
   
   

   sudo apt-get install openjdk-11-jre

   
   
   

   and hit Enter if asked.

   
   



3. For 64-bit Linux choose xdm-2018-x64.tar.xz and for 32-bit, xdm-2018-x86.tar.xz



4. After finishing download open Terminal and cd to the download directory; for example: cd ~/Downloads/Programs
   


5. 
   

   type tar -xvf xdm-2018-x64.tar.xz or tar -xvf xdm-2018-x86.tar.xz (according to the one you chose to download).

   
   
   

   NOTE: You may not want to extract the file using FileRoller or other softwares, as it may not extract it apporpiately.

   
   



6. type cd xdm-2018-x64 or cd xdm-2018-x86 (again, accordingly).



7. type sudo ./install.sh
   

Xtreme Download Manager is now installed on your system.
