This question already has an answer here:
I am trying to install Ubuntu 15.x without a bootable USB thumbdrive using UNetbootin. I was not able to install UNetbootin:
sudo apt-get install -f unetbootin
It resulted in unmet dependencies, and here is the exact error text:
The following packages have unmet dependencies: unetbootin: Depends: libqt4-network (>= 4:4.5.3) but it is not installable Depends: libqtcore4 (>= 4:4.6.1) but it is not installable Depends: libqtgui4 (>= 4:4.5.3) but it is not installable Depends: p7zip-full but it is not installable Recommends: extlinux but it is not installable E: Broken packages
I currently have Ubuntu 10.04 on my system.
