As per title, I wish to know if I can, after a successful 32bit setup and consequent software installations, update to a 64bit version.  I know how to partition (actually one of the solutions is to set /, /etc, /home, /var/www, and /opt as separate partitions) and I know that a clean install is way better than a dirty one, yet I would like to know if/how it's possible to do that.

I can't update 12.04 LTS. The Update Manager shows this:  CD/DVD 'Ubuntu 12.04 LTS _Precise Pangolin_ - Release i386 (20120423)' is required Please insert the above CD/DVD into the drive '/media/cdrom/' to install software packages from it.   The image I downloaded and burned to CD is from  the PC (Intel x86) desktop CD version. I burned many CDs but the result is the same.

The update from Ubuntu 13.10 to 14.04 LTS does not work it keeps showing me an error as could not calculate the upgrade, even when I want it to get updated from the terminal it says the same error. I did not use the beta its the final Ubuntu 14.04 LTS.I have restarted my laptop for like 5-10 times no change. Disabling the software sources also does not help.

The first thing I did after installing 16.04 LTS was to change my update server to Main Server. I can not find a similar option in Ubuntu 18.04.  How do I change it?

Not sure if there is a better communication mechanism for asking this question. Ubuntu 12 is EOL April 2017. Do corporations have any option to extend support on 12?  Thanks

I am currently using Ubuntu 12.04.2 32bit. I installed it using LiveCD.  Tomorrow, 23rd August 2013,Ubuntu 12.04.3 is released. I want to upgrade from Ubuntu 12.04.2 to Ubuntu 12.04.3 without using any LiveCD. Is it possible? If so please suggest me how can I do.  Actually while using Ubuntu 12.04.2 I have troubled with graphics. My graphics card is Intel i845G 64 MB. When Ubuntu starts it works fine and smooth without any lagging, but after sometime it hangs for few seconds (1 or 2 seconds) with a garbage screen and becomes sluggish. All windows and browsers start lagging and also it is not possible to play any video in any player (VLC, Movie Player, Xnoise, SMPlayer etc..).  I think Upgrading to Ubuntu 12.04.3 could fix my problem.  Any help will be greatly appreciated..    I've posted an answer to upgrade Ubuntu 12.04.x to 12.04.4.

I'm on Ubuntu 12.04 and want to know how to update Vim via the command line. What is the command to update this?

I was under the impression that upgrading to Ubuntu 14.04 was supported from all version between and including the previous LTS release (12.04). Why is it then, that update-manager (with and without -d option) will only offer to upgrade to version 13.10 from my Ubuntu 12.10 system? Even that only works when I change the updater settings from "For long-term support versions" to "For any new version."  Is it only possible to upgrade to 14.04 via 13.10?

To check whether I am using 32bit or 64bit Ubuntu. I looked in  and found this answer uname -a. If it is shown as i386, it will be 32bit and amd64, it will be 64 bit, but I got this result:  Linux mukund-ThinkPad-Edge-E431 3.8.0-35-generic #50-Ubuntu SMP Tue Dec 3 01:25:33 UTC 2013 i686 i686 i686 GNU/Linux   What is this i686? Is it 32bit or 64bit - I think  it is 32bit, because all the Debian packages which I installed in it are of 32bit, so can anybody please give a detailed explanation.

I just installed Ubuntu 12.04 LTS about 2 weeks ago. A week later a newer LTS came out. Now I know that I will get to upgrade in June but I don't know if I should upgrade or not. Please give me suggestions.
