UNSUCCESSFUL UBUNTU KERNEL UPGRADE TO 2.6.32-24

Hi all,
Just a month before 10.10 release,ubuntu 10.04 has created a problem for me.This post is more like a problem statement because I haven't figured out the solution yet.Last night I was upgrading my kernel to 2.6.32-24.After that my network manager was not running.I thought something was wrong with upgrade.So I rebooted and was shocked when I saw the grub menu.Previously, Grub menu used to show kernel versions 2.6.32-21, 2.6.32-22, 2.6.32-23 and their recovery options.Out of that 2.6.32-23 could not be used to boot.So,I used to boot through 22.But now,I could see only 23 and my system did not boot.when i tried to edit this option(generic kernel 2.6.32-23 in grub menu screen), I got first line as recordfail as shown in above image.

Then I tried to search on internet but found nothing important.Tried live cd of ubuntu 9.04 and tried to reinstall kernel.tried "sudo update-grub" and also grub-pc.Then checked /usr/src of 10.04 where I saw all previous kernel images along with 2.6.32-24.Now it looks like latest kernel couldn't be written but previous images were removed and only remained kernel is corrupt.So,I am not able to boot into ubuntu. Right now only solution is to reinstall 10.04.hoping a better solution from someone.

Download speed through apt-cacher and dependency problem with downloading so many packages at a time

hi,
I am not able to stop experimenting with ubuntu lucid lynx the time I installed it.With the apt-cacher,it's easy to download all the packages that you like.So,I was there with synaptic package manager and kept on selecting large number of packages.Finally I got a collection of 148 packages with 220 MB size.When I started to download,I saw variation of speed which is very common but I would like to point it out by some snap-shots.
1st picture shows the usual speed of download through apt-cacher which is 347 KB/s.2nd one shows unusual high speed 2843 KB/s.











But sometime we suffer low speed also.Just like this.


Now,apart from speed,there is one more thing that I would like to share.Since I selected a lot of packages and started downloading all,I got some installation problem.All the packages were downloaded but couldn't be installed properly.Very less packages were installed because of dependency problem.No idea how did it happen.Probably,when there is a huge number of packages ,some of them might have dependency due to others files in the download list.So,in my view,large number of packages should not be installed at a time.

By the way, I sent these dependencies report to developers officially.Here is one screen-shot which explains it.


Conclusion :- try installing less number of packages at a time.

performance review of ubuntu 10.04 lucid lynx

hello friends,
Ubuntu launched its Final release of lucid lynx 10.04 just 2 days before and I couldn't stop trying it as soon as I could.Reason is not that I was waiting eagerly for its final release.Real reason is that I had done some mistake in hard disk partition while installing slackware which caused me loss of linuxmint which I was using for a very long time.So, finally I thought to try fresh and final release of 10.04.
oh boy,What an OS.Surprisingly it can be called as the perfect OS.Lookwise,it has got better.Also,the most exciting feature is its boot time.Amazing boot time must have impressed everyone.Shutdown time is also faster.This has got attention of some people who are claiming that skipping disk check can also reduce boot time.Anyway,I don't want to create any controversy here.
Talking about look,It gives a sight of mac.The minimize, maximize and close buttons of window is on the left side which gives you feeling of working on mac.Anyway that feature was available previously also but not as default(a package "mac4lin" changes the look in that manner).New Gwibber social client is also very exciting.Gwibber can be configured to broadcast status on facebook,twitter etc. and to see other's status.
Recently "ubuntu tweak" became my latest crush as It has got nice and sexy packages which synaptic package manager didn't let me try directly.visit ubuntu-tweak.com for more info about tweak.As I am in a university which does not provide with a superfast internet connection but allows downloading packages with apt-cacher,I couldn't stop downloading all the packages which caught my attention.Well,It's definitely wastage of resource.
In final words,ubuntu 10.04 is just lovable and awesome and great experience so far.Don't know how soon the bugs will come out.Till then,enjoy lucid lynx.Happy open source.
