Everybody knows that Change is coming. So, let me help you guys to experience the change. Yesterday, Ubuntu team has announced Release Candidate for Ubuntu 10.04 LTS (Long Term Support, Updates up to 3 years) for Desktop, Servers, Cloud Computing and Netbooks. There would not be much change in Release Candidate and Final Release of Ubuntu 10.04 LTS. Please refer the release notes for further information. Now, time to upgrade, I am sure this would be adventure ride for novice Ubuntu user.I used to do this upgrade during BETA cycle, sorry for being late. Since, I had access to 8 MBPS Broaband Line, i could not stop my self for Ubuntu 10.04 RC Downloading. Because i have check the know issue, which is not affecting me too much, so i decided to on upgrade.
Here is my statics during Ubuntu 9.10 To Ubuntu 10.04 LTS (RC Release) upgrade process.
I started upgrade early in the morning in IST time zone with 8 MBPS Broadband Line. I was already running Ubutnu 9.10 with latest updates. During upgrade process, 1574 package was upgraded, 242 was new and 27 packages was removed. It took 45 minutes to download 1064 MB of data. Total upgrade time from Start to Reboot was around 3 hours on my Intel Dual Core machine with 4 GB Ram, i did Bath, Breakfast and checkout during this time. Last upgrade was of Ubuntu 9.04 under 40 Degree Celsius temperature @ Ahmedabad, this time i was in BLR with 20 degree Celsius temperature, Actually my laptop has heat problem, so this parameter was concerned for me.
Here is step to upgrade Ubuntu 9.10 to Ubuntu 10.04
Note: I would advise to take the backup from your existing system to be at safer side. Also, please make sure that you machine is connected with uninterrupted Internet to make upgrade smoother.
Step – 1:

Restart the system to complete the upgrade.
After successful reboot, you will notice purple Ubuntu Boot Splash. If everything goes fine it should boot perfect, which happened in my case, you may have to change themes and your existing desktop to give complete Ubuntu 10.04 LTS look.
I have also noticed 100% CPU utilization during “Cleaning Up” stage.

I hope this will also help for smooth upgrade from Ubuntu 9.10 to Ubuntu 10.04 LTS (RC Release).
Have Happy Upgrade….
I have been asked by lot of people about machine with Pre-Installed Ubuntu. So, Since last six month, i am finding Pre-installed Ubuntu on Desktops, Netbooks and Laptops in consumer / retail market (Say Malls / On-line / Off-line Hardware Shops ). I was looking for OEM Supplied Pre-Installed Ubuntu and their advertisement in Local Newspaper / Demo Machine @ Shops / On-line Shops, etc…. I have also documented few in past and blogged them, like Desktop with Pre-installed Ubuntu and Netbook with Pre-installed Ubuntu.
Now, time for laptop. Dell Vostro 1015 is coming with Pre-installed Ubuntu and it’s also advertise it [1] in Local News paper, check this one from Divya Bhasker, Gujarat. Here is PDF version of it.

[2] http://digitalimages.divyabhaskar.co.in//EpaperImages%5C07042010%5CDELL_INDIA_25X12_GUJARAT_MUMBAI_7TH_APRIL-large.jpg
So, now we have complete range of Pre-Installed Ubuntu Desktop / Laptop / Netbook. It’s clearly says that OEMs are interested in promoting Pre-Installed Ubuntu machines. It gives them freedom also.

Ubuntu 9.10 + Reliance NetConnect Broadband Modem (Huawei EC1260) + NetworkManager = Works Out Of The Box
Note: This article will help you to “Dial” your USB CDMA modem with Network Manager in Ubuntu, Assuming it’s already working fine with wvdial. If you are modem is not detected or working by wvdial, then it’s problem with Modem Detection in Ubuntu, if this is the case, then this solution is not for you.
Update: If you are on Ubuntu 10.04 LTS (Lycid Lynx) Beta – 1, please test ModemManager [1] and submit your response here [2], your feedback would help us to push this package to final build.

Update: If you are on Ubuntu 10.04 LTS (Lucid Lynx), here is new version for Modem Manager with fix (Very Very hackish way)
[1] https://launchpad.net/~hardik-dalwadi/+archive/ppa/+packages?field.name_filter=modemmanager&field.status_filter=published&field.series_filter=lucid
Since Ubuntu 9.10 release lot of people has complained about NetworkManager + Reliance NetConnect Broadband+ (Huawei EC1260) is not working out of the box, which was working fine with Ubuntu 9.04. This was happening due to bug in modem manager. I have just now uploaded patched version of modem manager which has solved the problem. So, No more gnome-ppp or wvdial, Here we GO:
Step – 1:
Get access of CLI and please make sure that Ubuntu 9.10 with uninterrupted Internet and make it up-to-date with latest udpates to be at safer side.
#sudo apt-get update
#sudo apt-get upgrade
Step – 2:
Please add my PPA to get patched version of Modem Manager. From here [1] you can find the detail about patched version of Modem Manager
[1] https://launchpad.net/~hardik-dalwadi/+archive/ppa
#sudo add-apt-repository ppa:hardik-dalwadi/ppa
+++ Snapshot From Live System +++

gpg: Total number processed: 1
gpg: unchanged: 1
person@CANONICAL-DESK:~$+++ END +++
Step – 3:
Now, check the current version of your Modem Manager (FYI). And again update the system to get header of patched Modem Manager from my PPA.
#dpkg -l | grep modemmanager
#sudo apg-get update
+++ Snapshot From Live System +++
person@CANONICAL-DESK:~$ dpkg -l | grep modemmanager
ii modemmanager 0.2.git.20091014t233208.16f3e00-0ubuntu1 D-Bus service for managing modems
person@CANONICAL-DESK:~$+++ END +++
Step – 4:
Now install Modem Manager from my PPA which is higher patched version from current version, after successful installation reboot the system.
#sudo apt-get install modemmanager
#sudo reboot
Step – 5:
Now after successful reboot, You should get the New CDMA Broadband option under Network Manager. I am assuming you have already inserted Reliance NetConnect Broadband+ Modem, if not please do that.Please follow the Images for more information on How to connect in GUI Mode.
Note: We have also tested with Tata Photon+ service with Huwei EC 1260 and Haier CE100 Modem. It’s working out of box. Please also test modems from BSNL / TATA / Reliance with NetworkManger and let us know in comment, whether it’s working or not. Your help would be much appreciated.
Please select New Connection, since Reliance NetConnect Broadband+ requires Mobile Number as Username / Password, You have to enter it manually. In case o Tata Photon+, You can select it from list.
I think it’s BUG with NM, it has not ask for Username / Password in manual selection of provider, we have to edit it again. It may not be the case in your scenario. So in my case i am editing settings again.
Since Network Manager is giving prirority to WiFi / Ethernet connect, you have to disconnect them to swithc over to your Reliance NetConnect Broadband+ Connection.
I am neither good developer nor good debuger, But since 9.10 upgradation / installation in my lab, i could not find the usb/devices file in default path, which is:
/proc/bus/usb/devices
And, it’s default path if you are on kernel 2.6.31 and usbfs is mounted by Init. Now, Ubuntu 9.10 is using upstart instead of init. It was working fine in Ubuntu 9.04. So it brought me in big world of usbfs. From Scott’s post usbfs: deprecate and hide option for !embedded. usbfs was enabled #417748 and disabled#488274 in Karmic Koala Released and Proposed version.
Ok, Ping back to original query, Ubuntu 9.10 is mounting debugfs instead of usbfs, regardless of usbfs in enabled / disabled in Kernel. So you will fine usb/devices file under /sys/kernel/debug directory, check below output:
person@CANONICAL-DESK:/proc/bus$ mount
/dev/sda6 on / type ext4 (rw,errors=remount-ro)
proc on /proc type proc (rw)
none on /sys type sysfs (rw,noexec,nosuid,nodev)
none on /sys/fs/fuse/connections type fusectl (rw)
none on /sys/kernel/debug type debugfs (rw)….

Currently i am testing this on Ubuntu 10.04 (Lucid Lynx) Alpha 3, and behavior is almost same. But it contains new version of usbutils, which has new shell script called “usb-devices”. It will give you connected USB buses with machine, regardless of where your usb/devices file is! and output is almost same. check below output
