Yum needs to be updated to work with Python 2.5.  Python 2.5 includes 
celementtree.  We have a separate celementtree package in the archive for 
use with Python 2.4.

I'm not sure why you'd bother with Yum in a Debian derived distribution, 
but if you run Yum with Python 2.4:

: python2.4 /path/binaryname

I'd guess it would work through that problem if celementtree is installed.

This probably hasn't installed the program you thought it would.  It
turns out that before Linus developed the distributed VCS called 'git'
there was already a project called the 'GNU interactive tools', or
'git'.  This is what the 'git' package contains.  You actually wanted
to install the 'git-core' package, which contains the dvcs.

This seems like the package misses a dependency.  That should be
documented in a bug filed against the package on launchpad.net.  On
the other hand, I'm don't think that installing programs through yum
is a good idea on an Ubuntu system.  I may be wrong here, though.  Why
do we even have that package? :)

No idea if that helps, but usually, if a package install is problematic
and you have 211 not upgraded packages, you should "sudo apt-get
dist-upgrade" first to make sure you have the newest version of
dependent packages and dependencies in general. Try the "-s" switch to
simulate the upgrade first, because upgrading 211 packages might be
huge. ;)

I hope it works after that.

The Ubuntu/Debian package for git, the revision control system, is
git-core, due to the "GNU Interactive Tools" claiming the package name
"git" first. Per the rest, I've got nothing. Hope this helps though.

It's not really worn out...it's still got 80% max capacity and over 2 hours
of battery life.

Sounds like you need to replace your worn out battery pack then.  Or 
just increase it to 5 minutes and see if that buys you enough time.

About the latter, see bug 91239: "Cannot unmount volume: show which 
application(s) still use the drive" [1]. This is a bitesize work that could be 
worth a bounty for somebody motivated.

That's a much better explanation than the error message. So you're
right, it's not a bug: it's two bugs. One is that the error message is
unhelpful, and the other is that the CD should be ejectable if the only
programs that were using it aren't running any more.

I tend to agree. Unfortunately it doesn't fit very easily into how the
automatic partitioner is designed right now, but please do open a bug
report for this (against the partman-auto package in Ubuntu).

I'd prefer if development discussions stayed here; what with OpenSSL and
everything I have very little time for forums threads right now.

I should also point out (because I gave out misinformation on IRC in a
moment of inattention) that this only works when you're using the manual
partitioner and select a partition to mount as /, or equivalent. If you
use the automatic partitioner and select "use entire disk", then that's
equivalent to wiping the whole drive and starting again.

Ah, OK. (I think this problem goes away once people stop being educated

https://wiki.ubuntu.com/UbiquityPreserveHome lists the items that are
removed. Essentially, it's everything that's owned by the packaging
system and that would be likely to create bizarre conflicts if bits of
it were from an old installation and bits of it were from a new one.
/home, /srv, /root, /usr/local, /var/local, and in general any
unrecognised parts of the file system are retained.

Previously on this issue:


Jef Raskin, who designed the typing-replaces-selection action, later
concluded that it was a mistake
:

In today's world we just select the old text and type away.
This method was not a good idea, in fact it can be disastrous.
It is easy to select text, forget it is selected (and the
selection might be off-screen), and then start typing. With the
nearly universally-available SELECT ALL command, it is easy to
lose whole documents this way. Nearly all users I've
interviewed have inadvertently lost text due to this design
error. While it requires [an] additional keystroke, the design
should have been (designers take note);

To replace text: select old text, tap DELETE, type new text.

There would be a couple of problems with changing this now. One is that
a non-trivial fraction (my wild guess would be 20 percent) of current
computer users are used to the typing-replaces-selection behavior. (The
rest don't realize it exists, except when they trigger it by accident.)
And because it is such a low-level behavior, relearning it would be
quite irritating.

The other is that dialogs often contain text fields with default values.
You can tab to a field, all its text is selected automatically, and if
you want a different value you can just start typing. If
typing-replaces-selection was dropped, some of these default values
might no longer be appropriate, because the cost of deleting the value
would have become greater than the benefit of providing it.

One smaller step would be to leave typing replacing selection, but to
make Ctrl+A the keyboard equivalent for Select Paragraph, rather than
Select All. Then it would still do what people wanted most of the time,
but the dataloss from typing Ctrl+A instead of Shift+A would usually be
much less severe.

The "It's All Text" Firefox extension does this.
 But adding the
complexity of a new window, with a completely different interface,
*just* for avoiding dataloss is a high price to pay. (To be fair, that's
not the only reason people use It's All Text -- it also lets them use
Emacs/Vi keyboard commands.) And you still need to remember to save
explicitly!

I think it would be better for browsers to behave the way good mail
clients do: while you're typing a message, they regularly and silently
save the message into the Drafts folder, so you can retrieve it later
even if an accident happens. Ideally browsers would save *the entire
page*, including text, selections in other form controls, scroll
position, and everything else, so you could get it back easily if you
closed it by mistake.
