• unable to display index.php

  - by user1683645

  I'm trying to load a website I've development and transferred from windows to ubuntu. I've installed apache2/php5/mysql and I've confirmed that it works by using the default index.html file displaying something like "It Works!". I've also created arbitrary folder containing some php file that I've run in firefox and it was displayed. But when I try to run my projects index.php I get a blank screen. I've consulted mirc about this and they say that it has to do with file permission. I've chcked the file permission on my index.php file and it is owner : rw r , group : r, others : read-only and execute is unchecked. What am I doing wrong?

• Unable to remove a file which have a name like a command argument

  - by Justin

  By inadvertance, I've created a file called -r into my home directory. Please don't ask me how and why, I don't recall. But the fact is that now I cannot get rid of it : rm -rf rm: missing operand Try 'rm --help' for more information. Other try : rm /-/r rm: cannot remove ‘/-/r’: No such file or directory Another one : rm \-r rm: missing operand Try 'rm --help' for more information. Is there a way to remove this file without deleting the whole directory ? Thanks.

• Unable to create an Ubuntu 12.10 USB stick on OS X

  - by Hex Bob-Omb

  I'm following the instructions to create a bootable Ubuntu 12.10 USB stick on OS X found here. I can do step 3 and hdiutil appears to work fine, but when I go to mount the resulting ubuntu.img file I get the same "no mountable file systems" error that I get when I try and open the ubuntu.iso file. No correctly sized volumes show up in diskutil list either. Any ideas? Using the most recent ubuntu-12.10-desktop-amd64.iso on Mountain Lion 10.8.2.

• Unable to install Steam 64bit - Wrong architecture (Lubuntu 12.04)

  - by Ian

  I'm on a new install of Lubuntu 12.04 on an Acer Aspire 5534 (specifications here, tl;dr: AMD dual-core 64bit) trying to install steam_latest.deb from the Steam website. When I open gdebi to install, it tells me that it's uninstallable because it's for a i386 architecture. I've tried installing ia32-libs (installed, no success), gdebi --add-architecture i386 (with and without --force, command unknown). This is all I've found to fix the problem, but none of it has worked for me. Any suggestions are welcome, thanks for your time.

• Unable to log in due to freeze, occasional error message

  - by Xianlin Xiong

  I'm new to Ubuntu. And I have some problems now. I downloaded Ubuntu 11.10 and burned it onto a CD. Then I load it in my conputer, it's easy. But when I finished those and restarted the computer, the problem comes: After I choose to log in the Ubuntu system,the screen stays in pink, and it can't jump into (about 30 min), and then I have no choices but to press Ctrl+Alt+Del to reboot. Another time I choose Ubuntu to log in, it shows on the screen that "BusyBox v1.18.4 ...... built-in shell ...... initramfs". However the Live CD works very well. What’s more, there is a Windows 7 partition on the hard drive. (Windows 7 is also okay.) But I leave more than 20GB on the hard drive to Ubuntu. When I installed Ubuntu, I only made two partitions (swap and /). I don’t know where the problems happened and how to deal with them. And I hope someone can help me out with the troubles.

• Laptop, unable to install discrete graphics card GTX 880M

  - by FoxyShadoww

  So I've bought the GT70 2PE Dominator Pro a few weeks ago and I installed Zorin OS 9 Ultimate on it. Today I tried to install the Nvidia drivers on my laptop since it has the GTX 880M, but my system became unbootable. Can anyone help me with this issue? I will write down what I've tried so far. This is what I've tried so far: Downloaded the newest Nvidia drivers from their website. Pressed CTRL+ALT+F2 to open the terminal page thingy. Logged in and got root access. Stopped the lightdm service. Ran the NVIDIA-Linux-x86_64-340.32.run installer. Pressed the accept button and right after that it told me the following message: The distribution-provided pre-install script failed! Continue installation anyway?. When I install anyway, it will crash my system and makes it unbootable, Does anyone know how to use my GTX 880M? Do I need to enable it on boot time somehow? Thanks for the support, Sapphire ~

• Unable to turn on seamless mode in VirtualBox

  - by user11658

  I'm not able to switch to Seamless Mode in VirtualBox with Ubuntu 10.04 or 9.10 as guest OS's. I have tried the seamless mode with XP as guest OS, and it works absolutely fine. The host OS is Windows 7. I have in-built Via/S3G Unichrome Pro IGP graphics, and I have allocated 30 MB out of 64 MB of graphics memory. I've also 1.5 GB of RAM. I also tried installing Guest Additions but it still didn't work. VirtualBox version is 4.0.4r70112. How can I get the seamless mode to work? Please help!

• Unable to record from USB sound card line-in connector

  - by tete

  I've been googling and struggling with this for a while but haven't been able to make this work. I bought a USB sound card (Encore ENMAB 8-CM) to record from its line-in connector. I'm not sure which input to pick in Audicity, but I'me sure I've tested them all. These are all the available inputs I have in Audacity. But there's no sound being recorded at all. I've already checked the device is working, so I really don't know if I'm doing something wrong. Any help will be very appreciated. Cheers.

• Unable to boot to Ubuntu

  - by nsk

  Just got a new laptop and removed Windows 8 and installed 13.10 using LiveUSB. Initially it was booting to "No boot media" but I was able to resolve it with boot-repair. I realized some of the items I need isn't supported on 13.10, so attempted to install 13.04 instead. Now without LiveUSB, the laptop just boots to "No boot media" but boot repair doesn't seem to be fixing it. Tried going back to 13.10, but no dice. After boot repair it says "Please do not forget to make your BIOS boot on sda1/EFI/ubuntu/grubx64.efi file!". GParted shows sda1 has the boot flag. Using Toshiba Satellite P50. Secure Boot disabled. UEFI enabled. Any help would be highly appreciated. http://paste.ubuntu.com/6366556/

• Unable to empty the rubbish bin

  - by gman

  When I attempt to empty the rubbish bin the preparing window opens but nothing happens. In testing I tried to delete 1 file from the rubbish bin and received a time-out error. No files are removed from the rubbish bin after this. I have added a screen shot that includes a display of system monitor that shows high CPU usage for trash and Nautilus; not sure whether it is related. Click for a full-resolution image. Also, on a separated note, Bleachbit was also freezing on me, which may or may not be related?

• Unable to Boot Into Windows 7 after Ubuntu 10.04 Update

  - by PlantGuy

  I'm running a dual boot Windows 7 / Ubuntu 10.04 system. I ran the Ubuntu update last night, and today when I tried to boot into Windows 7, it goes straight to the windows recovery on my Acer 5517 laptop. I've spent the entire day trying to resolve this with no success. I used my Windows 7 Recovery Disk to reset the mbr, but that didn't help. The system was working perfectly prior to the update. It appears that now Grub is pointing to the recovery partition rather than the primary partition. Any help will be greatly appreciated. I don't relish the idea of reformatting and starting from scratch.

• Unable to boot from new SSD after installing from USB

  - by user73725

  I'm using a new SSD with nothing on it. It's installed via USB drive, and boots from USB as well. While in Ubuntu I can see the SSD and other devices. When I install from the desktop (have tried from the boot screen as well), system restarts. It takes me to the boot screen, select boot from first hard disk, nothing, goes right back to boot screen. When I take the USB out, it hangs on "Verifing DMI." If I boot onto the USB I can see the correct files located in the SSD. I have a basic knowledge of computers. Give me any thing you think would help. No other OS's are loaded. Gigabyte ga-k8n-sli 1GB RAM AMD Athlon 64 x2 dual core 3800+ OCZ SSD Agility 3 120GB

• Unable to mount Windows (NTFS) filesystem due to hibernation

  - by yotamoo

  Whenever I boot Ubuntu, I get a message that it cannot mount my windows partition, and I can choose to either wait, skip or manually mount. When I try to enter my Windows partition through Nautilus I get a message saying that this partition is hibernated and that I need to enter the file system and properly close it, something I have done with no problem so I don't know why this happens.

• unable to boot from live USB!

  - by ramblinman

  Linux noob here. I was messing around with my new dual-boot (win7 and the latest ubuntu, 12.04 I think?) Long story short, I deleted some partitions that I shouldn't have. When I boot up the machine, I get: error: no such partition. grub rescue _ I know that I could probably fix this by booting from the live USB. But I can't boot from the live USB either! On startup, I can get "boot from drive" options by pressing F12. (This is how I installed Ubuntu in the first place.) But when I select the USB drive, I get this error: error: no such device: [long string of letters and numbers]. grub rescue _ I've searched around for a fix but most threads addressing the first problem suggest booting from live drive. And I can't do that! Any help much appreciated.

• Unable to install ZFS (Ubuntu 13.10)

  - by user209707

  I'm fairly new to Ubuntu and wanted to setup a server running ZFS/XBMC - The XBMC install went fine, however I ran into trouble getting ZFS working. Configuration : Ubuntu 13.10 (GNU/Linux 3.12.0-rc7+ x86_64) I attempted to install ZFS native using : sudo add-apt-repository ppa:zfs-native/stable sudo apt-get update sudo apt-get install ubuntu-zfs This failed to install due to "Module build for the currently running kernel was skipped since the kernel source for this kernel does not seem to be installed." Trying sudo modprobe zfs shows FATAL error : module not found. Here, they mentioned it was to do with lacking build dependences- I followed the answer which was to run sudo apt-get remove --purge ubuntu-zfs zfs-dkms zfsutils spl spl-dkms libzfs1 dkms Then, REBOOT. Then, do: sudo apt-get install linux-headers-generic build-essentia sudo apt-get install ubuntu-zfs " This leaves me in the same situation with "Building only for 3.12.0-rc7+ Module build for the currently running kernel was skipped since the kernel source for this kernel does not seem to be installed." when trying to install ubuntu-zfs. Trying sudo apt-get install --reinstall zfs-dkms also does not work.

• Win8 x64 Laptop (Samsung) unable to boot after installing Ubuntu

  - by user285872

  I posted here a while back and no one was able to help me so I am going to try to explain my problem better. I have a Samsung series 7 Ultrabook and I connected a USB optical drive with an Ubuntu 14.04 installation disc. I did not set or change any of my partitions, however, as I mainly wanted to just be able to boot from the disc and fool around with Ubuntu. Upon restarting my computer I get a blue-screen message saying: Recovery Your PC needs to be repiared The Boot configuration date file is missing some required information. File: \BCD Error Code: 0xc000000d You'll need to use the recovery tools on your installing media. If you don't have any installation media (like a disc or USB device), contact your system administrator or PC manufacturer. However I am never given the option to even try to boot to anything. When I turn my computer on the optical drive spins and then after a moment or two comes to a halt. I turned off safeboot and switched it to CSM (I believe that is what it is called) mode, and that makes it so when I turn my computer on it takes me to a Windows Recovery screen. I am able to change the date I want to recover and view all the applications installed, however upon recovering Windows says "All boot options are tried. Press key to recover with factory image using Recovery or any other keys for next boot loop iteration." It seems to be stuck in a loop. Can someone please help me?! I'm so confused and nothing is working!

• unable to start regionservers in HBase

  - by amsal

  I have a problem starting regionservers on slave PCs. When I enlist only master PC in conf/regionservers everything works fine but when I add two more slaves to it the hbase does not start. If I delete all hbase folders in the tmp folder from all PCs and then start regionserver (with 3 regionservers enlisted) the hbase gets started but when I try to create a table it again fails (gets stuck). I am using hadoop 0.20.0 which is working fine and hbase 0.92.0. I have 3 PCs in cluster, one master and two slaves. Also tell that is DNS (both forward and backward lookup working) necessary for hbase in my case? Is there any way to replicate hbase table to all region servers? I.e. I want to have a copy of table at each PC and want to access them locally (when I execute map task they should use their local copy of hbase table).

• Unable to execute binary file. Exec format error

  - by user2689020

  I recently heard about Breach, a Node.js based browser. I was following the instructions on http://codeforgeek.com/2014/08/download-install-breach-browser-ubuntu-14-04/ to install it but got the following error : breach-v0.3.22-alpha.6-linux-x64/__AUTO_UPDATE_BUNDLE__/exo_browser/exo_browser: cannot execute binary file: Exec format error After some googling, I found that it is because I am trying to install the 64 bit package on the 32 bit Ubuntu installation. I tried to find 32 bit package of the same but ended up with no luck. The browser is only available in 64 bit packet(as far as i know). So, My question is : Is it possible to somehow install it on the 32 bit OS or if any program available which can run 64 bit applications on the 32 bit OS. I have been googling around and found no help. Can anyone help me? I am using Ubuntu 14.04 (32 Bit). Thank You

• Upgrade to 12.04 LTS failed, unable to boot

  - by stargazergal

  I was trying to upgrade to 12.04 LTS, but the upgrade froze in the process (it was stuck for over 8 hours) and I had to do a hard reboot. Now when I boot up, I get the following: mountall /lib/x86_64-linux-gnu/libc.so.6 version 'glibc_2.14' not found. I'm not sure what I need to do from here. Do I need to go back to the previous version? Or can 12.04 still be installed? I don't want to lose any of my files. I am still new to Linux, so please give detailed step-by-step instructions.

• Unable to use separate X-Screen's GTX 550ti Ubuntu 12.10

  - by user12622

  I am currently trying to get from "Twin View" to using separate X screen's on Ubuntu 12.10, however I'm not having a great deal of luck. I am using an Nvidia GeForce GTX 550 Ti and am on driver version 304.51 Initially, when I turn on the separate X screens option, presents me on the 1 monitor with a box to accept the changes, however the 2nd screen goes black, and effectively, Ubuntu only seems to recognise the one screen. When I reboot, I boots back into Ubuntu with both screens working in Twinview. I'm not too sure where to start, but my xrandr can be found: Xrandr Any help is greatly appreciated, this is the last but one thing I need to make Ubuntu my only OS, so fingers crossed we can crack it :)
