You need to add no third party repository as Unetbootin is already in official Ubuntu repositories. — xangua, Jan 15 '17 at 06:25
@xangua if I try to just install i get following errors :- Some packages could not be installed. The following information may help to resolve the situation:
The following packages have unmet dependencies. unetbootin : Depends: p7zip-full but it is not installable Recommends: extlinux but it is not installable Recommends: unetbootin-translations but it is not going to be installed E: Unable to correct problems, you have held broken packages. — kerry, Jan 15 '17 at 06:40
Try running: sudo apt update, try again. What Ubuntu release are you using? Also please EDIT your question to add these terminal outputs. — xangua, Jan 15 '17 at 06:41
are u just want burn image to USB drive with use unetbootin ?. If yes, i can give alternative solution other unetbootin. — ryanw, Jan 15 '17 at 07:01
Have you tried software center ? I can see an installation candidate for unetbootin there. If you just want to create an usb installer for any iso, you could try the inbuilt Startup Disk Creator. Hope it helps. — Sourav Badami, Jan 15 '17 at 08:25
@Sourav Badami - I have tried that but it asks for a user and password that I have not given. Does not use my ubuntu user / pass so no idea what to enter for user / pass — kerry, Jan 15 '17 at 10:20
@Sourav Badami - sorry cant attach screen shot because i cant login. So cannot take screen shot - lets me boot from external usb drive but asks for user and pass that does not match my ubuntu install or any suggestions for standard ubuntu logins — kerry, Jan 15 '17 at 10:25
@David Foerster - added output from those commands to question. Thanks — kerry, Jan 15 '17 at 10:32
Getting frustrated - tried Startup disk creator instead - worked ok but asks for user / pass that is unknown to me - maybe i try etcher - does anyone have install instructions — kerry, Jan 15 '17 at 10:33
@David Foerster - sorry - new listings added to question - thanks again for your help — kerry, Jan 16 '17 at 02:29
Maybe off topic as question was about unetbootin but i tried using startup disk creator and it has created bootable usb drive but it is asking for user / pass and it does not match my user / pass on ubuntu or any of the default passwords i have googled - any ideas please — kerry, Jan 16 '17 at 02:32
Hi guys thanks for all your help but I have decided to give up on unetbootin. I tried ryanw solution to install etcher - so easy — kerry, Jan 16 '17 at 03:13
Only problem is whether to accept ryanw answer - I still cannot get unetbootin installed but etcher works and solves my real problem of creating a bootable usb hard drive - any advice.... — kerry, Jan 16 '17 at 03:52
I don't have an idea what causes the issue in your question but since all you appear to want is to make a bootable USB drive: possible duplicate of How can I create a Windows bootable USB stick using Ubuntu? — David Foerster, Jan 16 '17 at 10:04

if you just want burn image easy to USB drive.

You can use etcher as alternative unetbootin

i like this for simple UI

thanks - so easy to install but when i boot from hard drive it asks for user / pass and does not accept my ubuntu user pass - so i cannot login – kerry Jan 16 '17 at 03:14
do you mean default user & password for ubuntu? try username 'ubuntu' with an empty password. (note: input username without quotation marks just ubuntu) – ryanw Jan 16 '17 at 03:21
I am accepting this as correct answer - it did not help me install unetbootin but gave me a much simpler alternative i did not know about - thank you all – kerry Jan 17 '17 at 01:29
Look at gparted partitions for the drive after using this... it totally screws the USB drive. – wayofthefuture Apr 22 '17 at 18:36

mkusb can do it for you

make a simple Ubuntu install drive (live-only)
make a persistent live drive with Ubuntu
wipe the drive (overwrite the first megabyte or the whole drive with zeros)
restore the drive to a standard mass storage device

See the following link

https://help.ubuntu.com/community/mkusb

Install from the unstable repository, if you want the newest version
