Just introducing myself. I'm lwr32. I'm a iMac and Macbook user. I've got the
last iMac that
came out before the aluminum iMacs came out and my Macbook is 2 months old.
I've got an
old, slow, Compaq Presario 900 that came with Windows XP on it. I've
partitioned the drive
and put Ubuntu on it.

I really like Ubuntu and want to learn more about it. That's why I joined this
site. My email
comes to my Macbook right now. Once I get to know Ubuntu, I'll get my email
from it too.
My hubby put Upuntu v7.04 on the Compaq last year. Last night I started playing
with it and
decided to upgrade to the latest version. Right now I'm in the middle of
upgrading to v7.10
and will upgrade to 8 when it's available. The upgrade is taking forever. The
computer is
telling me 10 hours 55 min to complete install. I'm running the computer on an
ethernet
cable that's run through Apples Time Capsule. I don't know why it should take
so long to
install. Any ideas?

I'm pretty new to Linux myself - using Ubuntu and Kubuntu since January of
this year. I've never owned a Mac, but am pretty conversant with PC's having
used them since the early 80's. Guess that dates me!

This I do know, the latest version of both Ubuntu and Kubuntu is called 8.04
or Hardy Heron (released 2008, 4th month) and the next one is due end of
this month - 8.10 (Intrepid Ibix I believe). That's the way Ubuntu works,
it's updated twice a year and available for download free then. You can also
order free CD's from Canonical (the maker) and nominally priced ones from
other places. So if you want the latest either download 8.04 now or wait a
few weeks for 8.10. Install time should be well under an hour, plus some
more time to download and install any updates. I don't know why it's taking
you so long, but it means something is definitely amiss. Start afresh with
new CD's.

I have no idea what an "Apples Time Capsule" is, but your present
upgrading is likely trying to download a humongous amount of programs
and data, and the 10 hours sounds about right for a DSL connection.

As I recall from April of this year when my 7.10 system auto-upgraded
to 8.04, it downloaded some 600 to 700MB (perhaps more) of stuff to
do that upgrade. At that time I had a 6Mbps broadband connection to
the 'Net and it didn't take too long but I didn't time it -- I just
fixed dinner and watched a movie and let the upgrade run and it was
finished when the movie was over, so it took less than 3 hours for
the downloads and the upgrade install.

Time Capsule is a wireless backup system for the Mac that backs up drives to an
external device, supplied by Apple of course. It is both software and hardware.
TimeMachine is a utility that does backups and Restore in Apple OS.

There are Linux equivalents that will backup drives to an external device at
pre-set intervals or on demand. Just search the net and you will find more
options than you can imagine. There is a wide range of options, some easy and
some more difficult depending on how your view things. Easy for some people is
the commandline and for others it is the GUI approach.

You can use Google's Flyback as an equivalent to TimeMachine which is an Apple
backup and Restore utility. This is for Ubuntu 7.10, but should work with 8.04:

I have used Flyback and it is easy to use and not hard to get up and running,
especially if you have Java JRE installed already.

There are free applications such as: http://www.rsnapshot.org/ and konserve
which is in the repositories and part of KDE.

There are commercial apps such as: http://www.handybackup.net/linux-backup.shtml
and http://www.desktoplinux.com/news/NS2461279608.html

You can also do it from the commandline, if that is your thing:

The original poster can let us know more about what she had in mind and people
can share their experiences. Coming from Apple she would probably prefer the GUI
approach, but I don't know her preference re: this.

If it is just a matter of getting the hardware working, then she may want this:

There are two links in this brief article that I did not explore. You won't get
any help from Apple as they see Linux as the enemy and do all they can to ignore
their free, open source cousin.

She also might want to check out: http://thebadapples.info/ which is a Linux
podcast dedicated to Mac users. It has lots of useful info and if you email
Klaatu the podcaster, I am sure he would be able to help and even feature Time
Capsule if you request it. He also has a blog at:

Oh it could be a couple of things. The servers and the mirrors are busy. You are
sharing your internet connection through router. You are surfing on myspace or
some other band width hog. At the same time you want to upgrade.
