I've been trying to update for several days now, and it tells me that extras.ubuntu.com is unavailable. Why is it unavailable?

Recently I have installed an older version of Ubuntu on my old machine. Whenever I try to install any software, I get an error saying it couldn't be found:  $ sudo apt-get install vlc Reading package lists... Done                Building dependency tree        Reading state information... Done     E: Couldn't find package vlc

How can I fix this? I can't update anything at all.   I've tried to switch to my best server in the options.  When I do sudo apt-get update, this is what I get:     W: Failed to fetch     Unable to find   expected entry 'universe/binary-1386/Packages' in Release file (Wrong   sources.list entry or malformed file) E: Some index files failed to   download. They have been ignored, or old ones used instead.*   When I do sudo apt-get upgrade, I get this:     Reading package lists... Done      Building dependency tree             Reading state information... Done      0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.   the contents of my source.list:     deb  quantal universe restricted main   ....update: when I update, it looks for 'universe/binary-1386/Packages'  however, if I go to: ubuntu.mirror.rafal.ca/ubuntu/dists/quantal/Release with Google Chrome, I see that the file is actually named "universe/binary-i386/Packages" (it's with an i, not a 1) . how can I fix this and make it expect the proper package?

Ubuntu 11.10 is installed, and I have updated my system via Ubuntu Software Centre, and after the update 3 updates remain in the list. But I am unable to select them, the tickboxes cannot be checked and Ubuntu Software Centre gives no error when I try to check.  Also, below it says "There is no update to be installed" and even though there seems to be updates Install Updates button is unclickable.  What should I do in order to install these updates?

This is just silly:    If I try accepting (no, I wouldn't go through with it), it just says that the update is unavailable.  So why does it ask me to downgrade, and how do I get rid of this?

Lately, when I update, the process sticks on get deb:     [Connecting to archive.getdeb.net (144.76.200.19)]   The site -  - times out and the cloudflare message is in no way helpful.  Does anyone know why this repo and site are down? or perhaps anything else about it?  Thanks.

There are now errors when updating and I cannot install most software due to a corrupted  /etc/apt/sources.list   file. Is there a copy I can download to replace it?  The file would be for Ubuntu 12.04 (Final Beta) in the United States.

I wanted to update Ubuntu manually, because I used CDMA USB modem and connected using wvdial, but it won't able to update Ubuntu via Update Manager, because my Ubuntu won't showing "Connected" message via network-manager.  Can I update Ubuntu manually? Am I should download separate files, or use terminal instead?

So here is my story...  I was doing upgrades to ubuntu the other day, and the power went out right in the middle of the upgrade, so now when I try to do upgrades it keeps asking me if I want to do a partial upgrade. I have heard this is bad and should be avoided, I also know there is a way to fix this via the command line, but I can't remember how, nor can I find anything on the internet.  Any help would be appreciated. Thanks

Upon my observation, seems new packages will first appear in security.ubuntu.com, but if you upgrade later, they will appear in XX.archive.ubuntu.com (depends on your config),  Was that true ?

Using Ubuntu, I have a habit of running: sudo apt update sudo apt upgrade   on every startup. But for a month, I guess, there have been no updates whatsoever. The message shows: All packages are up to date  Now I am starting to worry. Can there be a fault in my update manager? As far as I know, I've made no changes to the package manager settings. But no updates for almost a month seems kind of weird. Any feedback would be helpful. Thanks.
