I am trying to install the Exodus wallet from a .deb file as I thought that would be easier but, when I try to install it from Terminal, I receive this message:

E: The repository 'cdrom://Ubuntu 18.04.3 LTS _Bionic Beaver_ - Release amd64 (20190805) bionic 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.

How can I solve this and install the .deb?

  • The message is telling you the installation media is not present (ie. cdrom; even if installed from other media; convention refers to installation medium regardless of what was used, to be referred to as a cdrom). The date 2019-08-05 tells you the date of the [installation] ISO; ie. 18.04.3 or older media (latest is 2020-August for 18.04.5 but your system was installed with 18.04.3 media from 2019-August). You can just disable it.

    Does this answer your question? Problem with sudo apt get update: The repository cdrom... does not have a Release file – guiverc Jul 04 '21 at 04:34

There are a few things we’ll need to do. First, edit a file so that the update manager is not looking for a CD/DVD with updates, then add the correct repository for updates so you can have an up-to-date system.

You don’t need to use the command line for these steps but, if you would like to, here’s how:

  1. Open Terminal (if it’s not already open)

  2. Edit the /etc/apt/sources.list file with root privileges:

    sudo vi /etc/apt/sources.list

    Note: You do not need to use vi. If you prefer a different editor, such as nano, feel free to use it. Be sure to keep sudo up front, though.

  3. Find the line that starts with CDROM and add a # at the start. You should now have a line that looks like:

    # cdrom://Ubuntu 18.04 LTS _Bionic Beaver_ - Release amd64

  4. Save the file. If you are using vi and are unfamiliar with the commands, you save and exit by first pressing Esc to exit editing mode, then :⇢ W⇢Q (Write & Quit)

    You should now be back at the shell.

With that first step done, let’s add the correct repo for Ubuntu:

  1. From the terminal, add the default repo: 
    sudo apt-add-repository http://archive.ubuntu.com/ubuntu
  2. Update apt: 
    sudo apt update
  3. If there are updates, you can install them with: 
    sudo apt upgrade
    Or: 
    sudo apt dist-upgrade

Now you might be ready to install Exodus. Rarely does a person need to jump through so many hoops ahead of time, but now the main stuff is complete.

  1. Ensure you have the latest version of libgconf installed: 
    sudo apt install libgconf-2-4
  2. Download the .deb file from Exodus.com/download. It’s easiest from a browser but, if you want to do it via the command line: 
    wget https://downloads.exodus.com/releases/exodus-linux-x64-21.7.2.deb
  3. Install the application: 
    sudo dpkg -i exodus-linux-x64-21.7.2.deb
  4. Open the application via the applications menu

That’s all there really is to it.
