Yes, we use virtualenv. Thank you.

I'd urge you to consider using virtualenv to manage python dependencies.

The only OS dependency you'd have, is python. You shouldn't care about
dependencies beyond that.

This is even more correct when deploying your application.

Re: Upgrading Ubuntu from 12.04 to 14.04

[Amos Shapira]

Beyond the original specific question - upgrades like this should be tested
using a Vagrant box, preferably also using an automatic provisioning tool
like Puppet (my personal preference) or Chef (obligatory mention) and
automatic testing using things like Cucumber, Spec, ServerSpec or perhaps
other testing frameworks.

That way you can write the tests to verify your current setup and repeat
the verification after the update.

Also - once you have automatic provisioning and testing in place, you
should consider treating the servers as immutable, i.e. once they are setup
they are not upgraded in-place but rebuilt whenever such a large change is
required. This way you are sure that what you run is exactly what you
tested in your Vagrant environment and what will be re-installed in case of
a disaster.

Re: Upgrading Ubuntu from 12.04 to 14.04

[Efraim Flashner]

I don't believe it is possible for a user to create a partition.  Of
course that is more of a brain-fart on my part, because it's not so
useful to your situation.  Gparted should be able to resize unmounted
ext3/4 partitions, and from there you can create a new partition, copy
your /home directory there and edit /etc/fstab to point to the new
partition.

I found these release notes: https://wiki.ubuntu.com/TrustyTahr/ReleaseNotes, 
but it looks rather short, and doesn't mention django.  Fortunately django has 
its own release notes here: https://docs.djangoproject.com/en/1.6/releases/ 
which should help with the upgrade.

Sorry I couldn't be more helpful, I've never used django.

Re: Upgrading Ubuntu from 12.04 to 14.04

[Uri Even-Chen]

Thank you, it's a good idea. At work my home directory is not in a separate
partition so it's not kept if I reinstall Ubuntu. Do you know how I can
create a partition and move it to a separate partition?

Why do you think it is not possible?  I do it all the time.
I  keep my home directory in a separate partition so when I upgrade (or
downgrade) the OS the home directory stays the same.

Upgrading Ubuntu from 12.04 to 14.04

[Uri Even-Chen]

Hi people,

I work at my job with Ubuntu 12.04 and we run Django 1.4.12 locally with
Python 2.7.3 and PostgreSQL. We want to upgrade Django from 1.4 to 1.6 and
I also thought it would be a good idea to upgrade Python to 2.7.6 and maybe
even 3, so I tried to upgrade Ubuntu to 14.04. But after I completed the
upgrade, Django didn't work and I couldn't even run migrations (with
South). I had to reinstall Ubuntu 12.04 and I lost all the files I had in
my home directory (because I chose not to keep Ubuntu 14.04) except some
files that I backed up. My questions are:

1. What do we need to do in order for Django to work with Ubuntu 14.04?
2. Why isn't it possible to reinstall Ubuntu 12.04 after upgrading to 14.04
and still keep all the files in my home directory, while not keeping all
the other files (the operating system files)?

Thanks,
Uri Even-Chen
