  • TypeError: Cannot call method 'hasOwnProperty' of null, while creating a QMLscene window

    - by tomoqv
    I am trying to make a simple Ubuntu Touch web application with Qt Creator. I have set up a new project according to the tutorial and committed the files to Bazaar. I have set a url instead of the default index.htm in the qml file of the project. Using build-run loads a QML Scene window with the desired webpage, but Qt Creator yields the following output: Starting /usr/lib/i386-linux-gnu/qt5/bin/qmlscene -I /home/tomas/ubuntu-sdk/SL-planner -I /usr/bin -I /usr/lib/i386-linux-gnu/qt5/qml /home/tomas/ubuntu-sdk/SL-planner/SL-planner.qml unity::action::ActionManager::ActionManager(QObject*): Could not determine application identifier.

Provide your application identifier in $APP_ID environment variable. file:///usr/lib/i386-linux-gnu/qt5/qml/Ubuntu/Components/MainView.qml:257: TypeError: Cannot call method 'hasOwnProperty' of null My SL-planner.qml looks like this: import QtQuick 2.0 import Ubuntu.Components 0.1 import QtWebKit 3.0 /*! \brief MainView with a Flickable WebView. */ MainView { // objectName for functional testing purposes (autopilot-qt5) objectName: "mainView" // Note! applicationName needs to match the "name" field of the click manifest applicationName: "com.ubuntu.developer.tomoqv.SL-planner" /* This property enables the application to change orientation when the device is rotated.

  • lucid 10.04 LTS => Precise 12.04.1 : upgrade doesn't work

    - by Rastom
    I googled and looked into all unkown issues on ubuntu forums but I can't figure out why a 10.04 LTS server won't detect the last LTS 12.04.1. I guess since 12.04 is a fresh dist, not much is reported for related issues Here is what I did : apt-get update apt-get upgrade apt-get install update-manager-core it was already installed so no update for this package. I checked : /etc/update-manager/release-upgrades [DEFAULT] # Default prompting behavior, valid options: # # never - Never check for a new release. # normal - Check to see if a new release is available. If more than one new # release is found, the release upgrader will attempt to upgrade to # the release that immediately succeeds the currently-running # release. # lts - Check to see if a new LTS release is available. The upgrader # will attempt to upgrade to the first LTS release available after # the currently-running one. Note that this option should not be # used if the currently-running release is not itself an LTS # release, since in that case the upgrader won't be able to # determine if a newer release is available. Prompt=lts I also checked my sourcelist before running apt-get : /etc/apt/sources.list deb http://archive.ubuntu.com/ubuntu/ lucid main restricted universe multiverse deb http://archive.ubuntu.com/ubuntu/ lucid-security main restricted universe multiverse deb http://archive.ubuntu.com/ubuntu/ lucid-updates main restricted universe multiverse deb http://security.ubuntu.com/ubuntu lucid-security main restricted deb-src http://security.ubuntu.com/ubuntu lucid-security main restricted deb http://security.ubuntu.com/ubuntu lucid-security universe deb-src http://security.ubuntu.com/ubuntu lucid-security universe deb http://security.ubuntu.com/ubuntu lucid-security multiverse deb-src http://security.ubuntu.com/ubuntu lucid-security multiverse # deb http://landscape.canonical.com/packages/hardy ./ # deb-src http://landscape.canonical.com/packages/hardy ./ and then following Ubuntu guide for Precise upgrade the command below should work : root@xxxxxxxxx:/etc/apt# do-release-upgrade -d Checking for a new ubuntu release No new release found So am I missing something ? The server was accessing outside through a proxy but I grant direct access to this server to avoid any Internet access problem or redirection but no clue... Any help would be appreciated

  • Easiest way to send mail from Linux Server

    - by QAH
    Hello everyone! I want my server to send me email alerts every time it does things such as run a backup. I have tried to setup programs like Sendmail, Postfix, etc on my Ubuntu Server box and it is really a pain for me to get it working. Is there any online service or some easy gateway where my server can send email alerts? If not, is there any easy scripts to get a Linux mail program up and running? Thanks

  • Bare-Metal Restores of Linux Servers with Tivoli

    - by Chad P
    We currently use IBM Tivoli to back up our Linux servers and we are looking for suggestions on the best way to restore to bare metal. I've read IBM's doc on this issue. Is that still relevant or is there a better way? Also, how do you handle testing a restore to a vm or another piece of hardware on the same network that the original server lives?

  • resume file copy linux

    - by Andrew Johnson
    How do I resume a copy of a large file in linux? I have a huge file (serveral gigabyes) partially copied to a network drive, and it took a long time, and it was mostly done before the copy operation stopped due to a network problem that is now fixed. How do I resume the file copy. I don't want an inefficient script, and ecp didn't work (it doesn't seem to work for large files).

  • Randomly poor 2D performance in Linux Mint 11 when using nvidia driver

    - by SDD
    I am using: - Linux Mint 11 - Geforce 560ti - nVidia driver (installed via helper programm, not from nvidia page) The third party nvidia drivers radomly cause very poor 2D performance. Radomly because the performance can be very great, but after the next reboot or login become very poor. After another reboot or login, this might change again to better or worse. I have no idea why and how and I need your help. Thank you.

  • I need to know the reasons why learning Linux Shell Scripting (BASH) benefits me as a PHP developer

    - by Ahmad Farouk
    I have been developing web sites/applications using the LAMP stack for almost 5 years. Currently I am interested to dig more into Linux OS, specifically BASH but from a web developer perspective, not from sys admin perspective. I am not intending to administrate Linux Servers. Only, I want to know, does learning shell scripting benefit me as a PHP developer? Does it make me a better, more skilled developer, or just its something irrelevant? Reasons, and examples are highly appreciated. Thanks in advance.

  • Configure Dual Boot, Windows 7 and Ubuntu 12.04 with or without EFI

    - by Keroak
    I have just installed Ubuntu 12.04 on a laptop with Windows 7 but I don't get to boot from Ubuntu. First, during the installation I made these partitions (may be too many): /dev/sda1 FAT32 SYSTEM 200Mb boot (EFI boot, i guess) /dev/sda2 unknown file system 128 Mb msftres (Windows Boot Manager) /dev/sda3 NTFS OS 100 Gb (Windows 7) /dev/sda4 NTFS DATOS 315 Gb (Data partition) /dev/sda5 ext4 28 Gb (/home) /dev/sda8 unknown file system 1 Gb biog_grub (i'm not very sure why i made this one) /dev/sda6 ext4 17 Gb (/ Ubuntu 12.03 installed withou errors aparently) /dev/sda7 linex-swap 2 GB (swap) I can boot from Windows perfectly. Actually I tried to configure Windows Boot Manager with EasyBCD but it doesn't recognize any boot entry. Anyway, I added an Ubuntu Entry and it configured it automatically. Now I have boot entries the Windows 7 one that appear to work and the Ubuntu 12.04 that it prompt a "No application found" message. I re-started from a USB with Ubuntu and tried to fix GRUB from the command-line and with boot-repair. No results. As far as I understand I have to tell the Windows Boot Manager where my Ubuntu boot loader is. So I have two problems: Actually, I don't know where my Ubuntu boot loader, GRUB or GRUB2 or whatever, is. I don't know how to set my Ubuntu entry in Windows Boot Manager. I guess using BCDedit.exe as EasyBCD didn't show me the entries. Anyway, I don't know what parameters to use. I read several articles about it but i didn't find out anything useful.

  • No password mysql under linux?

    - by ripper234
    I was told that mysql user, similar to root user, by default "has no password". Not an empty password, but rather "no password". I wasn't aware this situation was possible - I thought every user on a linux had to have a password. Am I wrong? Can you point me to a link that explain this?

  • Avoid linux out-of-memory application teardown

    - by Eddie Parker
    I'm finding that on occasion my Linux box runs out of memory and it starts tearing down random processes to deal with it. I'm curious what administrators do to avoid this? Is the only real solution to up the amount of memory (will upping the swap alone help?), or is there better ways to set up the box with software to avoid this? (i.e., quotas, or some such?). I'd appreciate some feedback. Cheers, -e-

  • Linux Mplayer Instead of flash any distro/browser

    - by data_jepp
    The thing is that flash sucks for linux on 64-bit, performance vice. Due to this I actually download every clip to a temp folder and play the file while it's being downloaded with mplayer. This works really nice. Flash is not to play a video. Does there exist a plugin for this for any browser? I tried google, but I can't find the right words to search for.

  • Networked filesystem with user level security for linux

    - by Konrads
    Hi, I want to enable file sharing between servers and clients, both linux. I don't want to rely on machine trust like in NFSv4 because client users will have root privileges. What are my options besides SMB (SAMBA)? Does OpenAFS support user level authentication & access? Using mounted WebDAV/ftp/sshfs seems silly for LAN.
