re: unetbootin problems

Thanks, but I managed to get dd working, and am now back on Ubuntu 16.04 which is working much better without any wifi issues, usb writing issues. Cheers again, S

re: thanks!

The output of your dd for ubuntu.iso looks ok and "normal" to me. Your dd uses the default block size, bs=512 (bytes). Output is about 1.4 GiB, and the time in seconds looks reasonable. I assume you renamed your Ubuntu iso to be ubuntu.iso (in your Download folder).

The usb worked and let me reinstall ubuntu, so all is good. Thanks for your reply!

I,m with Qqmike and use dd almost exclusively. The only graphical writer i found reliable is Suse Studio Image Writer which comes standard with any Manjaro distro. I'm not sure if it is available for Kubuntu

[Qqmike]

Or, if you burned it to a USB stick, did you check the stick?

Ah, yes. Maybe technically correct, but ... first time I heard about this issue. I usually rely on dd to report any errors--which does sometimes require proper interpretation--and if not, then I go with it. Fact is, I've never had any problems at all doing a dd iso-to-usb, not even dd errors.

I downloaded the .iso from the kubuntu site. So it has to be the real one. ...

You misunderstand. The question isn't "Is the ISO the real one?". The question IS "did the ISO download correctly without errors? That is determined by using md5sum to determine if the checksum matches that given on the download site for that ISO."
And, when you burn it to a DVD did you use the "Validation" option to validate that the burned DVD has the same checksum? Or, if you burned it to a USB stick, did you check the stick?

This is the output of dd:

I'm beginning to suspect that your 16.04 installation was done with an ISO that wasn't check summed, and neither was the LiveCD. The dd command on my six year old laptop running Xerus never fails to create a bootable LiveUSB. However, the dd method doesn't create a persistent LiveUSB.

The problem with UNetbootin is explained here.
If you don't want to use dd then using the tools that come with Kubuntu is explained here.

As far as auto-mounting USB sticks and CDs/DVDs, my installation does it nicely, which is another reason why I suspect a faulty ISO or burn.

[siologen]

Thanks for all the support through the thread, I also have a sneaking suspicion there is something off with the way kubuntu 16.04 handles usb mounting, it does not seem to mount the drives automatically like ubby/zorin....but we shall see. Thanks again!!

[Qqmike]

I will try dd with a fresh download of ubuntu for now and report back with a screenshot of the output in terminal?

Sounds like a plan. And maybe others with fresh eyes or some specific 16.04 experience will drop in and have a look, too. I'm no expert -- I just know how to run dd to get this job done!

using Kubuntu 16.04

Ah, yes. Many of us are still using the Kubuntu 14.04 LTS, waiting at least 2 more months before trying 16.04. Who knows why, but it sounds like a quirk in 16.04. Now, to be clear: Unetbootin may have problems no matter how/where you run it, from 14.04 or from 16.04 or from Ubuntu. You can google that and see. But the dd method would most certainly work fine in Kubuntu 14.04. We're pretty friendly around here, come back if you want to mess around some more with Kubuntu . Perhaps someone else who is running 16.04 could jump in on this, too.

[siologen]

Thanks again for all advice. I am just stuck with creating a usb for any other distro with unetbootin using Kubuntu 16.04. Sorry for any confusion.

[Qqmike]

OK. You know, if you have a machine that boots by UEFI, you need 64-bit Kubuntu; and then re-boot with the USB, enter your firmware/UEFI/BIOS setup, select the UEFI version of the USB that shows up in your boot menu(s), and boot that way.

[siologen]

I tried, but got a non bootable usb....so it seems I am stuck on kubuntu, thanks again, but pulling my hair out is useless. I will ask a friend to send me a live ubuntu usb in the post.
