Instillation crashes mid instillation upon pressing continue of account details setup,

[josiah lloyd]

[rational]
Crashes the installer if the user presses continue.

[test case]
1) Get a Kubuntu desktop image
2) Install and when reaching the account details setup, press continue

2) shouldn't crash the installer anymore

[regression potential]
Fix has been in quantal for a while and fix is obvious. There's only one path leading to that specific bit of code and that bit was guaranteed to always crash, so it really can't get any worse.

happens anytime tried installing, Even on multiple computers and multiple instilation disks, Unable to install Kubuntu, Has Wiped windows partitions

It looks like the crash happens here:

What is the hostname you enter when installing?

Seems that it fails compliance validation and then triggers the crash.

[Rienk de Vries (rienk-w200)]

Thanks Harald !

Your remark triggered the solution for me. I had the same issue when installing, the errors in lines #957 and #806.
First this happened when trying to install a 32 bit Kubuntu 12.04 from a USB stick, and today again when trying to install a _x64 Kubuntu 12.04 from a cd. (at first I thought I had a corrupted image or download)

I guess the User Menu does not like spaces. At first, when filling in my full name (Rienk <space> de <space> Vries), and also a computername containing a space, the installer will crash. I assume because the installer sets the hostname by taking whatever one puts in the computer name field, and when there is a space there, one will wind up with an invalid hostname.

Right now Kubuntu is installing, after having filled in those textboxes without using any spaces.

Cheers,
Rienk

[Harald Sitter (apachelogger)]

Ah, sensible enough. I have a fix and will try to get it deployed as soon as possible. There is just a simple coding error that is triggered when the hostname fails validation (which it would do in case of spaces as a hostname with spaces is not allowed on Linux).

Thanks for the information.
