Re: Xenial startup disk creator and custom ISO

[Darren Landoll]

I've been using the same process that worked for me on Ubuntu 15.04 install
images, so might be something related to the new startup disk creator in
16.04. I will take a look at the pages you provided and maybe also try
using genisoimage instead mkisofs that I'm using now to generate the new
*.iso file.

Re: Xenial startup disk creator and custom ISO

[Tong Sun]

By posing to Ubuntu-devel-discuss mailing list, I presume that you don't
mind dropping down to and work from command line. If so, read on,

What you are trying to accomplish is quite a mouthful if you haven't done
it successfully before, so I recommend to break the steps up, and reach to
the creating a custom Ubuntu Install CD step as the final step.

Steps that you should be able to do before that, are at least the
following, from easy to a bit difficult:


*Boot Ubuntu 14.10 directly from CD image*
https://sfxpt.wordpress.com/2014/11/15/boot-ubuntu-14-10-directly-from-cd-image/


*Ubuntu frugal multiboot installation without burning any CD/DVD*
https://sfxpt.wordpress.com/2014/02/18/ubuntu-frugal-multiboot-installation-without-burning-any-cddvd/

The last one is how you put bootable Ubuntu on HD or USB:

Make sure you can boot off the official squashfs before customizing your
own.

The instructions might be out of date, it'd be nice to update the wiki
page with latest verified/new steps, if someone successfully finishes
the battle of getting it working.

I have successfully created bootable (both when using USB Creator and
simple Disks tool copy which equals to 'dd') live CD remix of 16.04
LTS, where I switched from mkisofs to genisofs [1].

Permit user to change expired password

[Mark Foley]

I don't think this is a bug per se as Ubuntu probably does not officially
support this setup, so I'll start with the developers list. Redirect me if there
is a more appropriate place to post this ...

I am using Ubuntu 15.10 as a Active Directory member host (i.e. client
workstation) using Samba 4.1.17 on Ubunutu to the AD/DC controller running Samba
4.1.23.  The Ubuntu workstation uses the user.py module of samba-tool to manage
passwords and I have a menu desktop config that lets me change the domain
password.  All that works fine. 

The big problem is when the user's password expires. On the LightDM greeter
login box I do get a "Password Expired" message, but no opportunity to change it
(Windows forces the user to a 'change password' dialog). If I try to log in
anyway, I can't, and the system goes a bit nuts.

Trying to log in remotely via ssh no longer works.  Port 22 is still open, but
the connection times out.  I can login via LightDM greeter as a local (not AD)
user, but it takes a long time (I tried logging in, got a blank greeter
background, waited a very long time, gave up but left it as-is, came back the
next day and noticed I was logged in).  Once logged in I tried `su` and `ssh` -
got the password, but it hung there for 6 minutes before I got the shell prompt
(su).  I tried running `top` to see what was going on, but again, many minute
delay. When if finally did run I see that windbindd is eating 99.7-100% of CPU
cycles. I'll worry about the windbindd issue later ...

What I'd like to see is, if a password is expired, the user gets a dialog that
requests a password change.  I have such a dialog (from Samba), but I need it to
be displayed when there is an expired password.  I'd be happy to work on this
myself, but I need some direction.  What program(s) have to do with logging in?

Assistance would be appreciated as I am trying to move our office way from
Windows to Ununtu workstations, which I think could certainly be a wave of the
future.

Thx -- Mark
