Installation of Kubuntu 16.04 crashed

[Mike]

First problem was that the locale information could not be updated. I set it manually and skipped the step. After i entered all information for my user, the installer crashed.

I just restarted the USB stick without UEFI. It seems that the problem only exists if starting in UEFI mode.

Status changed to 'Confirmed' because the bug affects multiple users.

[Mathieu Trudel-Lapierre (cyphermox)]

That crash shouldn't be in any way related to UEFI -- what crashed was the locale setup utility, which complained about '/etc/default/keyboard' being unavailable. This has all the hallmarks of a crash we had during the development cycle and that was fixed prior to the release.

I want to be extra safe, so we'll do some more tests with daily images of 16.10 -- but this certainly isn't crippling enough to the images to warrant "critical" importance: we know at least some installs complete successfully.
