How the Ubuntu update works

Hi friends,

I am planning to use Ubuntu in my new project. I would like to update my packages using ubuntu package updater.

  • Whether the update manager will keep a backup of the old packages or will it be replaced by new packages?
  • Can I use the update manager to update kernel as well?

My apologize if this should not be asked in this mailing group.

Hi friends,

I am planning to use Ubuntu in my new project. I would like to update my
packages using ubuntu package updater.

- Whether the update manager will keep a backup of the old packages or will
it be replaced by new packages?

Generally when you update your system you can find the previous
packages at /var/cache/apt/archives, unless you clean up your cache.

- Can I use the update manager to update kernel as well?

Sure, but only if you're running the official Ubuntu kernel. For
Maverick please visit https://wiki.ubuntu.com/ARM/OMAP for more info
on how to grab the pre-installed image. In case you want to create
your own image, please see http://elinux.org/BeagleBoardUbuntu.

Unfortunately for Maverick there was a decision to stay with upstream
kernel even for OMAP 3, so not everything is supported by default. In
case you're running a community kernel, then you need to find out the
best way to update your kernel.

My apologize if this should not be asked in this mailing group.

Fell free to also join #ubuntu-arm on freenode if you need any help.

Cheers,

With most images you can go either way with Maverick.

First check for a "/etc/flash-kernel.conf" Different demo images have
had different versions over the years, basicly remove the "exit" and
the ubuntu kernel will become default if you install it form the
repo's..

example /etc/flash-kernel.conf middle of:
http://github.com/RobertCNelson/omap-image-builder/blob/master/tools/fixup.sh

If you'd like to stay on community kernel, every dist/revision has an
install-me.sh script in it's kernel version directory on rcn-ee.net

So for latest maverick stable:

Look at: http://rcn-ee.net/deb/maverick/LATEST

Which for stable "today" shows:
http://rcn-ee.net/deb/maverick/v2.6.35.6-l5/install-me.sh

so "wget http://rcn-ee.net/deb/maverick/v2.6.35.6-l5/install-me.sh"
and then ". ./install-me.sh" and you'll have the latest stable
kernel...

Regards,

Just wanted to reply to this thread and confirm that installing the
OMAP3 Maverick pre-installed netbook image, and then updating the
kernel via Robert's update script works fine. I believe the pre-
installed image installs 2.66.33-something...I installed the current
STABLE kernel, rebooted and it came back up fine!

I also installed the omapfb drivers, but have not yet attempted the
SGX install yet.

Good work Robert!

Cheers,

Ian

I installed the minimal, then use aptitude to install Gnome and other stuff I needed. Rebooted and running with Gnome.
There was a big update yesterday, "aptitude update", then "aptitude safe-upgrade", rebooted and it's OK.
The problem I had with the original install was with sound input channels so I couldn't record, both with the on board audio and a USB audio card. I have not yet tested to see if the upgrade has fixed it.
