    You need to add no third party repository as Unetbootin is already in official Ubuntu repositories. – xangua Jan 15 '17 at 06:25
  • but if i try to install i get the following:- – kerry Jan 15 '17 at 06:36
  • @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
  • Can you attach a screen shot of the window ? – Sourav Badami Jan 15 '17 at 10:22
  • @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
  • @everyone - thanks so much for all your help..... – 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?](http://askubuntu.com/questions/289559/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

etcher

  • 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
