  • "Failed to fetch" while updating

    - by Farouk BA
    I'm trying to update from ubuntu 12.10 lately but I keep getting the "Failed to fetch" error. W: Failed to fetch ht tp://security.ubuntu.com/ubuntu/dists/quantal-security/Release Unable to find expected entry 'independent/binary-amd64/Packages' in Release file (Wrong sources.list entry or malformed file) W: Failed to fetch ht tp://archive.ubuntu.com/ubuntu/dists/quantal/Release Unable to find expected entry 'independent/source/Sources' in Release file (Wrong sources.list entry or malformed file) W: Failed to fetch ht tp://archive.ubuntu.com/ubuntu/dists/quantal-updates/Release Unable to find expected entry 'independent/binary-amd64/Packages' in Release file (Wrong sources.list entry or malformed file) W: Failed to fetch ht tp://archive.ubuntu.com/ubuntu/dists/quantal-backports/Release Unable to find expected entry 'independent/binary-amd64/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. I changed the server and deleted the source lists from /var/lib/apt/lists/ like some answers say but still. This is really annoiying.

  • Updating "Inactive" Chunks

    - by Conner Bryan
    In my game, the only chunks (4x4 areas of tiles) in memory are the ones that the player is in. However, chunks need to have updates applied to them over time. A (likely) well-known example would be MineCraft: even if the player isn't in a chunk, the wheat still needs to grow over time. My current solution is to call a method and pass in the time since the chunk was active.. but what if the chunk depends on nearby chunks for information, i.e. vines spreading or similar? Is there any reasonable solutions to this problem, or should I simply not depend on nearby chunks?

  • Updating query results

    - by Francisco Garcia
    Within a DDD and CQRS context, a query result is displayed as table rows. Whenever new rows are inserted or deleted, their positions must be calculated by comparing the previous query result with the most recent one. This is needed to visualize with an animation new or deleted rows. The model of my view contains an array of the displayed query results. But I need a place to compare its contents against the latest query. Right now I consider my model view part of my application layer, but the comparison of two query result sets seems something that must be done within the domain layer. Which component should cache a query result and which one compare them? Are view models (and their cached contents) supposed to be in the application layer?

  • A tip: Updating Data in SharePoint 2010 using REST API

    - by Sahil Malik
    SharePoint 2010 Training: more information Here is a little tip that will save you hours of head scratching. See there are two ways to update data in SharePoint using REST based API. A PUT request is used to update an entire entity. If no values are specified for fields in the entity, the fields will be set to default values. A MERGE request is used to update only those field values that have changed. Any fields that are not specified by the operation will remain set to their current value.   Now, sit back and think about it. You are going to update the entire entity! Hmm. Which means, you need to a) specify every column value, and b) ensure that the read only values match what was supplied to you. What a pain in the donkey! So 99/100 times, a PUT request will give you a HTTP 500 internal server error occurred, which is just so helpful. Read full article ....

  • Error after updating from Ubuntu 10.04 to Ubuntu 10.10

    - by Emerson Hsieh
    Note: This was posted 6 months ago. Please read my answer below. I updated to 10.10 from 10.04 last week. After rebooting it shows "error "prefix" not found" for half a second and then it's stuck at a flashing line forever!! I installed 10.04 again and I didn't upgrade to 10.10 directly because the flashing line looks creepy and I don't want to see it again. What should I do now?? PS: I want to upgrade to 10.10 I am using wubi I hate that flashing line

  • Updating, etc., automatically

    - by Steve D
    Is there a way to set up Ubuntu 12.04 (or earlier versions) so that all recommended updates are done automatically, say once a week? When I say automatically, I mean no password entry or user intervention required. This sounds like a stupid request, so let me tell why I'm asking. My grandfather knows nothing about computers; he uses his solely to read Yahoo! mail. I want to get rid of his clunky, spyware-ridden Windows XP and install Ubuntu. I want to set it up so when he turns the computer on, after a couple minutes, voila!, Yahoo! mail, already signed in, ready to go. The problem is I don't want to have to go over there every week or so and make sure everything is up-to-date, he hasn't accidentally installed any spyware, etc. So can this be done? Is this the best way to set things up for my grandfather? Are there other things I should be worried about when it comes to keeping things hassle-free for him? Please don't post anything like "why not teach him how to... blah blah blah". My grandfather is 80 years old and has made it clear email is the only thing he will ever use a computer for! Thanks!

  • inserting or updating values into null textboxes [closed]

    - by tanya
    this is my sql table structure create table cottonpurchase ( slipNo int null, purchasedate datetime, farmercode int , farmername varchar (100), villagename varchar (100), basicprice int null, premium int null, totalamountpaid int null, weight int null, totalamountbasic int null, totalamountpremium int null, Yeildestimates int null ) I want to fill in the null values in my sql with actual values and not leave them null but I want to do that from my winforms app form! But if I do that it just adds a new record when what I want is for it to update the record which has, for example, farmercode = 2, farmername = blaah, and so on. I also want to enter this in the same records as in farmercode = 2 and the corresponding corresponding basic price = ... , everytime i do it it ends up making a new record and not in the existing one.

  • Git, auto updating, security and tampering?

    - by acidzombie24
    I was thinking about hosting my private project on my server (i may use 'gitolite') and have a copy on my local machine as backup (git clone then automated git fetch every few minute). I want to know what happens if there is a bug gitolite or somewhere else on my server and the source code and git repository has been tampered with? Will my backup also be corrupted? will i easily be able to revert the source using the history?

  • Issue updating domain name servers from BlueHost to AWS

    - by cowls
    I am trying to migrate my site hosting from bluehost to AWS cloud based service. I have the site up and running on AWS with an elastic IP configured, it loads fine when I specify the IP address in the browser. I have gone into Route 53 on the AWS console and created a "hosted zone" for the domain. I then created a new record set of type "A" using the IP address as the value. I have a domain name registered with bluehost. Ive logged into the bluehost account and updated the domain name servers to point to those specified in Route 53 in the AWS console. When I hit the IP address directly the site loads, however it doesn't load when using the domain name (I get a google chrome oops error page saying page is not found) I've tried using this site: http://dns.squish.net/ to debug but it seems to be giving me the correct results. fizaclegems.com 300 IN A 107.20.209.78 Where 107.20.209.78 matches the elastic IP configured in the AWS console. This is the result it gives for all 4 name servers. Am I missing a step here? Does anyone know what else I should be doing or looking for?

  • Error when updating enumerated value?

    - by igrad
    Once upon a time, there was a Player class (simplified version) enum animState{RUNNING,JUMPING,FALLING,IDLING}; class Player { public: Player(int x, int y); void handle(); void show(); ~Player(); private: int m_x; int m_y; animState playerAnimState; } There was also a "handle" function-member, which took care of all movement and collisions for the player: #include "player.h" void Player::handle() { if(/*Player presses 'D' key*/) { m_x++; playerAnimState = RUNNING; } //Other stuff that is just there to look nice Through lots of experimentation with "//" and "/**/", I've found that I consistently get an error at "playerAnimState = RUNNING." Have I broken some enumeration rule? Does my laptop really suck that bad? I hate to post a "fix my code for me" question, but I'm not very seasoned with enums.

  • SMTP mailbox unavailable - intermittent and self-inflicted

    - by user134451
    I have an app that runs daily, sending confirmation emails to dozens of customers. Emails are sent using SMTP with authentication. The app also has some error handling, and occasionally anonymous SMTP is used to notify the webmaster that an e-mail issue has been encountered (a malformed email address, usually). Whenever these warning notifications are sent, the customer notifications that follow throw an error: "Mailbox unavailable. The server response was: 5.7.1 Unable to relay". The customer notification emails are sent, but my app drops into the exception handler. And all subsequent customer notification emails have this problem. Everything is fine next time the programs run, until a webmaster warning email is sent. Anyone have an ideas what would cause this? My first thought was that the client didn't like being switched back and forth between anonymous to authenticated modes. I created a separate client for each mode, but that didn't help.

  • Battery died when updating from 12.04 to 12.10

    - by Aksh BriZmohun
    I started the update and went to sleep but I forgot to plugin AC adapter. When i woke up, laptop was off. I plugged in the AC cord and turned it on. Ubuntu boots and it is on 12.10 but may items are missing and neither gnome nor unity seem to work properly. It's also very slow and freezes sometimes. Is there a way to correct all those issues ? or revert back to 12.04 then re update to 12.10 without losing my data ?

  • updating from 8.04 to a newer version?

    - by user175802
    I have an old system. It doesn't have a DVD drive, and I think the cd drive is a bit wonky. The only disk that I have been able to get to install is an old (official) 8.04 Kubuntu disk. No disk that I've burned on a few systems works. They check out, but they don't seem to survive the install (another issue). I thought once I got a version on that I could update over the web, but no luck. It appears EOL. No updates seem to be available, or software to install. Is there a way? I'd like to get it to as new a version as possible. The next step would be to pull the drive and get a new one, but I'd rather not.

  • Updating to linux-image-3.2.0-26-generic occupies all disk space

    - by user42228
    I just ran a normal update through the update manager that wanted to update me to linux-image-3.2.0-26-generic. The installation paused halfway with a message that the root was full. I checked the disk usage, and noticed that one of the newly installed files: /lib/modules/3.2.0-26-generic/modules.ccwmap took up 63GB(!). Compared to the previous version: /lib/modules/3.2.0-24-generic/modules.ccwmap that took up only 4KB it seems like something went awfully wrong! As mentioned the update was paused when i ran out of disk space. There is no option in the update dialog to cancel or perform rollback on the update. Is it asking for trouble to kill the update manager? Any ideas as to what went wrong, and what I can do to remedy it? It's only minimal how much space I can free on that partition (without deleting the above mentioned file). If it is any help, the update was paused after this: Examining /etc/kernel/postinst.d. run-parts: executing /etc/kernel/postinst.d/dkms 3.2.0-26-generic /boot/vmlinuz-3.2.0-26-generic

  • Can't access external USB storage after updating to 12.10

    - by user99252
    I installed Ubuntu 12.04 after Windows failed me and Samsung got a bit pissy about providing any help. I then upgraded to 12.10 after a week or two and suddenly my external USB devices no longer work. The same devices I plugged in are no longer recognised. As I say, I'm only a user of Ubuntu for a fortnight, so any advice and directions to very simple instructions, would be appreciated greatly. I've seen this asked elsewhere, but the advice was to ask again if you needed clarification.

  • Synchronizing (updating) published files

    - by MucMug
    How can I update a published file and maintain the same URL? After saving an update of a published file on my desktop, it will automatically "synchronise" with the corresponding files at UbuntuOne (and it does). Problem is that the "new file", actually the updated file with the same name, is no longer published. Pressing the publish button results is a new URL. I now have to mail new URL's and change embedded links, as old URL will result in a failure to find the updated file (or indeed any file). I am not sure if it is a bug or a design flaw (maybe intentional?), but it seems strange to me.
