I received the following failure on brave browser installation attempt:
$ sudo apt update E: Malformed entry 1 in list file /etc/apt/sources.list.d/brave-browser-release-.list (Component) E: The list of sources could not be read.

Resolution was achieved by the following steps:

1. get distro name
   $ lsb_release -sc

2. Then clear the problem by deleting those files with malformed apt entries:
   $ sudo rm /etc/apt/sources.list.d/brave.list

3.Add Key
$ curl -s https://brave-browser-apt-release.s3.brave.com/brave-core.asc | sudo apt-key add -

4. Added my distro name "disco main"
   $ echo "deb [arch=amd64] https://brave-browser-apt-release.s3.brave.com/ disco main" | sudo tee /etc/apt/sources.list.d/brave-browser-release.list
