I've installed Ubuntu Mate 18.04.2 to its own 40GB partition on an 80GB HDD. The computer is online, and I've updated Ubuntu with all offered updates.

I want to run ddrescue to copy files from an ailing drive to a new one. Both drives are the same size. Both will be slaved into the system.

I know how to open the Terminal but I'm not sure what commands to use to install ddrescue and its GUI. The actual copying, I think I can handle.

GNU DDrescue (command line tool), since it available on default repositories — you only need:

sudo apt install gddrescue

The ddrescue-gui which is GUI frontend for original GNU DDrescue is available from PPA:

sudo add-apt-repository ppa:hamishmb/myppa
sudo apt update
sudo apt install ddrescue-gui
  • E: The repository 'http://ppa.launchpad.net/hamishmb/myppa/ubuntu groovy Release' does not have a Release file. N: Updating from such a repository can't be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details. It doesn't work for me, what should I do?

  • @Unknown123 Meaning the PPA doesn't support your distribution, from what I look it seems your Linux OS is not Ubuntu ? Try execute lsb_release -a in terminal.

  • No LSB modules are available. Distributor ID: Kali Description: Kali GNU/Linux Rolling Release: 2020.2 Codename: kali-rolling Yes It is not. I couldn't find the ppa for kali. What should I do next?
