12.04 upgrade problem

Did you uninstall drivers before updating??? One fix might be to put in the live cd you used to install and see if you can reinstall it. I know this is a drastic solution but there could be many problems as to why it failed -broken packages for example. You could try mounting the / partition via live cd and running sudo apt-get autoremove
Hope this helped

New question #196466 on Ubuntu:
https://answers.launchpad.net/ubuntu/+question/196466

Problem with 12.04 upgrade (previously had 11.10 running in dual-boot config under Win XP). Upgrade got as far as "Installing Packages" stage then hung. Tried to shut down but could not so hit power button. On re-starting PC and selecting Ubuntu, it goes through initial stage ok but then hangs before login screen. Any assistance very welcome, only been using Ubuntu for a few months so novice stage!!

thanks for reply. No, I did not uninstall drivers before updating. I did
original 11.10 install from Ubuntu website so I don't have a cd. I think I
might be able to get to cmd line on boot-up so I could possibly try running
sudo apt-get autoremove. As I've only been using Ubuntu for a few months as
a trial (along with XP) then if I have to go back to a clean start it's not
the end of the world - thanks again

It might be useful if you can get a live cd or live usb for the future. You say you did original install from website -do you mean you are running under wubi?
If not then it should be fairly easy to troubleshoot the problem. The easiest way to get around your problem is to :
Ensure that you have backups of your files.
Then you will need a live cd somehow.
To be honest just clean installing 12. 04 might be the quickest way round unless you have a lot of programs installed.To backup your files you could (again a live cd helps (try to burn it from another computer or something) mount your home partition and copy it. - that should backup your files - not programs though. Then just click install and you can reinstall 12.04 without any more partitioning..
If you really can't get a live cd I can post one to you if that would help :-)
Any questions just ask :-)

If you do have a wubi installation, please ask more questions. If you are not sure, pleas ask. A wubi installation is VERY different from a partition installation. If you have valuable data in either Windows or Ubuntu, you need to rescue this before going any further. A live-DVD or Ubuntu will be essential to you.

Today I installed Ubuntu 12.04 (precise) for the first time on my computer. I did wubi installation on my E drive. I am unable to update because of following error :

E:Unable to parse package file /var/lib/apt/lists/partial/archive.ubuntu.com_ubuntu_dists_precise-security_main_i18n_Index (1)

I am new to Ubuntu so may need solution in details. Thanks in advance.

try this: run them one by one

sudo apt-get autoremove

sudo apt-get autoclean

then try this: it isnt the same error but it might work

sudo mv /var/lib/apt/extended_states /var/lib/apt/extended_states_tmp

from ( http://sathyasays.com/2009/11/08/how-to-fix-e-unable-to-parse-package-file-varlibaptextended_states-1-error-in-synaptic-or-apt-get/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+SathyaSays+%28Sathya+Says%29 )
However I would strongly recommend that you at least consider installing it as a side by side installation--it is not difficult to do and provided you have backups nothing can go wrong. If you do decide to dual boot (also know as that ) then ill be happy to help sort out any problems you might have.

Wubi is not as good as a proper install

Hope this helps

Dear Anton,

Thanks for writing. I tried almost everything but couldn't solve the problem. I also installed only Ubuntu by formating my whole drive but problem persisted. I became frustrated of Ubuntu (it was my first experience). I am big fan of Open Source Concept. But this one disappointed me drastically.

May be in future I will try when such problem will not persist. Thanks a lot.

Andy

If you can't get ubuntu to work you may have more luck with Linux mint. Unfortunately this is the problem with open source, sometimes errors come up. Although I has been using linux for about a month now and it has worked for me so far. It sounds like a buggy disk you burnt. Try burning the iso image you downloaded to a dvd at the lowest speed. I understand that this can be very frustrating (dealing with errors when you don't really want to have any in the first place). I hope that you find something that works for you

P.S. ignore the previous post i created a new account by mistake

Arnand, were you able to run Ubuntu from the live-DVD by booting into it without Windows running? If not please give a bit more information so we can try to fix the problem.
