  • Installing 12.04 through Update Manager on a XP/ubuntu dual-boot

    - by Madeline Mcormick
    I currently have a dual-boot system running XP Pro SP3 with Ubuntu 10.04 LTS. I decided to upgrade to 12.04 using the Update Manager from the network and NOT using ISO CD version. Now that I am in the middle of 12.04 installation, I have this immense fear that this upgrade from update manager on the network server may affect my Win XP OS and may render it un-bootable. I tried backing up files while its upgrading to Ubuntu but it does not recognize any external media like external HDD. What should I do?

  • Getting "server certificate verification failed" during apt-get update

    - by mydoghasworms
    I am trying to update a system using an HTTPS package mirror located here: https://mirror.ufs.ac.za/os/linux/distros/ubuntu/ubuntu/ However, during apt-get update, I get the following message: Packages server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none If you visit the site in your browser, you are warned about the site's certificate, but I trust the site, so it's not an issue for me. I assume I must be able to add this exception somewhere for apt to proceed. Can you tell me where and how?

    - by user285982
    I am using Ubuntu 10.10 64 bit, and I can browse the internet fine. I am typing this using the machine. When I attempt to use the Ubuntu Update Manager to update to 11.04, I get this error message: Failed to Fetch Fetching the upgrade failed.There may be a network problem.

  • How to force update-grub to use UUID?

    - by user276851
    When I run "update-grub", the file "grub.cfg" will contain lines like this. menuentry 'Ubuntu...' { ... linux /boot/vmlinuz... root=/dev/md124 ... ... } For the line of linux, is it possible to let it use UUID? Like, linux /boot/vmlinux... root=UUID=xxx Right now, every time after I do update-grub, I have to manually edit the line to use UUID. Otherwise, the boot will fail. Thanks for the help.

  • How can I disable update checking on boot?

    - by Chauncellor
    I'm running off of a thumb drive with very average read/write speeds and automatic update checks makes the bootup far less pleasant. Since I manually update via apt there's truly no need to notify me like on a normal desktop. In older versions of Ubuntu there was an item to disable this behavior. On 12.04 this is no longer the case. would it be the 'unattended-upgrades' item in /etc/init.d? If yes, would simply removing the init script would solve my problem?

  • Ubuntu 12.04 - Read only file system+computer crash/freezes after an update that got interupted

    - by user288542
    I've run into an error with Ubuntu while I was updating it. During the update my power went out and interrupted the update. When I finally got power and booted my computer, I received an error, telling me to remount ./ and basically told me I could press S to skip or F to fix. (I forgot exactly what it said) but anyways, I originally pressed F to fix, but that didn't solve the problem, so then I went into the terminal and I tried to remount that way, but I couldn't execute because it's stuck in "file system read only." Sorry, my description of the problem is dull. I'm debating on just reinstalling, but I have a ton of files I would like to keep, about 3+ years worth of websites I've built. Is there a proper way to fix this?

  • Ubuntu 11.10 not showing up in GRUB bootloader after update and restart :(

    - by beginer
    I was using ubuntu 11.10 with gnome-shell. I installed various useful softwares and ran system update using update manager which ran smoothly and asked me to restart my comp at the end. I restarted it to find that Ubuntu entries were missing from the GRUB bootloader and only memory test and windows are showing up. I took a lot of pain in installing various important softwares and cannot afford a re-installation. Tried to boot from the live cd and installed boot-repair and after running it .. it wasnt working properly .. it was just showing that it was "scanning systems" for more than an hour. Kindly help. Thank you ..

  • 12.4 LTS after update fails to login

    - by user111839
    An update today (30-11-2012) on 12.4 lead to failure to log in. The system gets through its boot process then presents the logins, on choosing any of these immediately returned to log-in screen with no error. Machine is an AMD FX 64 on an Asus MB using the built-in graphics. If no one knows what this might be, what's the alternative distro to Ubuntu? It's the second time something like this has happened after an update in three months, kudos to the Ubuntu team but I need more reliability. Cheers, thanks to all.

  • Update Manager Partitions

    - by user170585
    Perhaps this is completely stupid, but here's my inquiry: I have Ubuntu 12.04 installed on an external hard drive. On that HD there are 4 partitions. Two for operating systems, two for swap (unnecessary but I like it that way). The actual computer itself has Windows 7. If I use the Update manager to update to 12.10 or even 13.04, would the new Ubuntu install itself on the same partition it already was on? The other operating system I'm running on the Hard Drive is Lubuntu, for when I need to run Linux on older computers, if that matters. Thanks, Adam

  • How would I go about updating my electronic circuit simulator's 'electricity'?

    - by liqwidice
    I have made an application which allows the user to place down wires, power sources, and inverters on a virtual circuit board. All connections between tiles are automatic, as shown here: As you can see in the last image, the updating of power throughout this grid is not yet functioning. I think I understand how to do this updating conceptually, but getting it to work in my program is appearing to be much more difficult than I first imagined. My source code can be found here. If you have any tips as to how to I might approach this monstrous task, please let me know. EDIT The goal here is to simply get a working application. Getting tiles to pass on power to their neighbors is quite easy, but the tricky part is getting wires to "unpower" after the removal of a power source. The size of the grid is just 18x18, so efficiency really isn't a factor, for those wondering.

  • Updating a specific key/value inside of an array field with MongoDB

    - by Jesta
    As a preface, I've been working with MongoDB for about a week now, so this may turn out to be a pretty simple answer. I have data already stored in my collection, we will call this collection content, as it contains articles, news, etc. Each of these articles contains another array called author which has all of the author's information (Address, Phone, Title, etc). The Goal - I am trying to create a query that will update the author's address on every article that the specific author exists in, and only the specified author block (not others that exist within the array). Sort of a "Global Update" to a specific article that affects his/her information on every piece of content that exists. Here is an example of what the content with the author looks like. { "_id" : ObjectId("4c1a5a948ead0e4d09010000"), "authors" : [ { "user_id" : null, "slug" : "joe-somebody", "display_name" : "Joe Somebody", "display_title" : "Contributing Writer", "display_company_name" : null, "email" : null, "phone" : null, "fax" : null, "address" : null, "address2" : null, "city" : null, "state" : null, "zip" : null, "country" : null, "image" : null, "url" : null, "blurb" : null }, { "user_id" : null, "slug" : "jane-somebody", "display_name" : "Jane Somebody", "display_title" : "Editor", "display_company_name" : null, "email" : null, "phone" : null, "fax" : null, "address" : null, "address2" : null, "city" : null, "state" : null, "zip" : null, "country" : null, "image" : null, "url" : null, "blurb" : null }, ], "tags" : [ "tag1", "tag2", "tag3" ], "title" : "Title of the Article" } I can find every article that this author has created by running the following command: db.content.find({authors: {$elemMatch: {slug: 'joe-somebody'}}}); So theoretically I should be able to update the authors record for the slug joe-somebody but not jane-somebody (the 2nd author), I am just unsure exactly how you reach in and update every record for that author. I thought I was on the right track, and here's what I've tried. b.content.update( {authors: {$elemMatch: {slug: 'joe-somebody'} } }, {$set: {address: '1234 Avenue Rd.'} }, false, true ); I just believe there's something I am missing in the $set statement to specify the correct author and point inside of the correct array. Any ideas? **Update** I've also tried this now: b.content.update( {authors: {$elemMatch: {slug: 'joe-somebody'} } }, {$set: {'authors.$.address': '1234 Avenue Rd.'} }, false, true );

  • How to update maven local repository with newer artifacts from a remote repository?

    - by Richard
    My maven module A has a dependency on another maven module B provided by other people. When I run "mvn install" under A for the first time, maven downloads B-1.0.jar from a remote repository to my local maven repository. My module A builds fine. In the mean time, other people are deploying newer B-1.0.jar to the remote repository. When I run "mvn install" under A again, maven does not download the newer B-1.0.jar from the remote repository to my local repository. As a result, my module A build fails due to API changes in B-1.0.jar. I could manually delete B-1.0.jar from my local repository. Then maven would download the latest B-1.0.jar from the remote repository the next time when I run "mvn install". My question is how I can automatically let maven download the latest artifacts from a remote repository. I tried to set updatePolicy to "always". But that did not do the trick.

  • What are your suggestions for best practises for regular data updates in a website database?

    - by bboyle1234
    My shared-hosting asp.net website must automatically run data update routines at regular times of day. Once it has finished running certain update routines, it can run update routines that are dependent on the previous updates. I have done this type of work before, using quite complicated setups. Some features of the framework I created are: A cron job from another server makes a request which starts a data update routine on the main server Each updater is loaded from web.config Each updater overrides a "canRunUpdate" method that determines whether its dependencies have finished updating Each updater overrides a "hasFinishedUpdate" method Each updater overrides a "runUpdate" method Updaters start and run in parallel threads The initial request from the cron job server started each updater in its own thread and then ended. As a result, the threads containing the updaters would be terminated before the updaters were finished. Therefore I had to give the updaters the ability to save partial results and continue the update job next time they are started up. As a result, the cron server had to call the updater many times to ensure the job is done. Sometimes the cron server would continue making update requests long after all the updates were completed. Sometimes the cron server would finish calling the update requests and leave some updates uncompleted. It's not the best system. I'm looking for inspiration. Any ideas please? Thank you :)

    Possible Duplicate: Please insert a disk into SD/MMC - Vista problem Hi I tried pushing my 2GB micro SD card using the inbuilt card reader.

  • Vim move cursor one character in insert mode without arrow keys

    - by bolov
    This might seem a little too overboard, but I switched to vim and I so happy about the workflow now. I try to discipline myself not to use the arrow keys, as keeping the hands on the alfa-keys all the time is such a big thing when writing. So when I need to navigate I get out of insert mode, move in normal mode and get back in insert mode. There is an exception where this is actually more disrupting: I use clang complete with snippets and super tab which is great. Except every time I get a function auto completed after I fill in the parameters I am left with the cursor before ) so to continue I have to move the cursor one character to the right. As you can imagine this happens very often. The only options I have (as far as I know) are : Escla or ?, and I am not happy about neither of them. The first one makes me hit 3 keys for just a simple 1 character cursor move, the second one makes me move my hand to the arrow keys. A third option would be to map CTRL-L or smth to ?. So what is the best way of doing this? //snippets (clang complete + supertab): foo($`param1`, $`param2`) //after completion: foo(var1, var2|) ^ ^ | | I am here | Need to be here | denotes cursor position

  • Windows Vista - Can't start any program without choosing "Run as administrator"

    - by Dave Forgac
    A friend called me saying that her computer recently said it was applying a Windows update when it was shutting down. Now when logged in as her normal user whenever she tries to run any program from the start menu or from a shortcut on the desktop she gets the following popup: "Windows cannot access the specified device path or file You may not have the appropriate permissions to access the item" If she right-clicks and chooses 'Run as administrator' the program will run. We checked the Windows update history and it said the update was applied successfully and that there are no updates available. Unfortunately I'm in a different city so I don't have physical access to the system to look at it any further. Has anyone had a similar problem or have any suggestions?
