15.04 - nightly (21 March 15) - installer hangs after the 'prepare' section (doesn't get to 'Disk setup'

[yossarian_uk]

I tried to install Kubuntu 15.04 nightly AMD64 (21 March 2015)

The installer hangs after selecting '3rd party software' / 'Download updates while installing' - it doesn't get to 'Disk setup'

The 'workaround' is to cancel, start the installer again and it will get to disk setup and finish the install.

I have recreated the issue over 4 times, as soon as you cancel the next time it succeeds.

I hopefully have attached system logs , but here are the last 40 lines in syslog:-

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. It would help us a lot if you could test it on a currently supported Ubuntu version. If you test it and it is still an issue, kindly upload the updated logs by running only once:
apport-collect 1434892

and any other logs that are relevant for this particular issue.

Thanks for the response, it is about 3 yrs too late now though.

I do not have the issue with later versions of ubuntu, i think I found a convoluted workaround 3 yrs ago (can't for the life of me remember what that was..)

Feel free to close as no one sane would be running 15.04 now..
