i am trying to install the Startup Disk Creator on Ubuntu Mate (Release 20.04.01 LTS 64bit)

Supposedly it should be pre-installed but I tried with command “usb-creator-gtk” and got the message that it cant be found but installed. I then tried to install trough command “sudo apt install usb-creator-gtk” This gave me the following error messages:

E: Type 'dep' is not known on line 1 in source list /etc/apt/sources.list.d/brave-browser-release.list
E: The list of sources could not be read.
E: Type 'dep' is not known on line 1 in source list /etc/apt/sources.list.d/brave-browser-release.list
E: The list of sources could not be read.

I read in an different answer that “sudo apt update” /upgrade should do the trick but this gave me error messages as well

E: Type 'dep' is not known on line 1 in source list /etc/apt/sources.list.d/brave-browser-release.list
E: The list of sources could not be read.
E: Type 'dep' is not known on line 1 in source list /etc/apt/sources.list.d/brave-browser-release.list
E: The list of sources could not be read.

How should I proceed?

Thank you for your help!

Your brave-browser-release.list file has a typo. Instead of dep, it should be deb. Fix this file, then update apt. The message should disappear.

To correct the file, do this:

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

  2. Open the source file with the help of sudo:

    sudo nano /etc/apt/sources.list.d/brave-browser-release.list

  3. Find dep and change it to deb

  4. Press Ctrl+X to exit

  5. Press Y when asked if you want to save the changes

  6. Update apt:

    sudo apt update

    Depending on how long this file has been broken, you may have a lot of pending updates to install.

As for the disk creator, it’s hidden in a right-click action on Ubuntu MATE. Right click the .iso file and select “Open with Disk Image Writer”
