Some Linux Distributions (e.g., Fedora, Arch Linux, openSUSE) have made the app package into system repositories.

For Ubuntu, users may choose to install it via either Snap or Flatpak package.

Option 1: Snap package

    sudo apt install flatpak

After installation, just search for and launch it from either GNOME overview or start menu depends on your desktop environment.

If the app icon is not visible, either log out and back in, or try running the command below to start it from terminal:

flatpak run eu.scarpetta.PDFMixTool

Uninstall PDF Mix Tool

To uninstall the software package, either use Ubuntu Software (or App Center) for the Snap package.

Or run the command below to uninstall Flatpak package:

How to Create Bootable Live USB Drive in Ubuntu 18.04/18.10

Last updated: October 5, 2018

To do a fresh Ubuntu install, I’m always first burning the ISO image into USB drive, and then boot up with the USB drive and install Ubuntu into hard disk.

I used to use Unetbootin to create the startup USB drive. However, it has been dropped from Ubuntu repositories since Ubuntu 18.04 LTS. And Unetbootin .bin package is not well burning the ISO image in my case.

In this quick tutorial, I’m going to tell you that the default Gnome USB Creator can do the job easier and more straightforward:

1. First download Ubuntu iso from releases.ubuntu.com, and plug-in your USB drive.

2. Search for and launch usb creator (Start Disk Creator) in application menu:

3. When it opens, click the Other button and choose the downloaded ISO image.

Finally click the Make Startup Disk button to start burning the ISO into selected USB drive.

That’s it! When everything’s done, boot the USB drive in your machine and try or install Ubuntu.
