    Unhappy Computer crashes after bootup after attempting to install a wifi card

    I attempted to install a new trendnet wireless pc card, since my previous card died. I could not find a driver for Ubuntu linux 12.04 so found the win-wrapper solution and attempted to install that. Win-wrapper appeared to install ok, but when I added the driver it gave me an error. I then tried a usb wifi adapter and it was automatically recognized and worked. When I restarted my computer however, Now my computer is crashing shortly after bootup.
    Evidently this process corrupted something.
    Here is the series of messages that pop up shortly after booting up:
    "A volume of software packages has been detected"
    "Would you like to open it with the package manager?" I click on "start package manager"
    "Enter password" I enter password
    "Unable to get exclusive lock - this usually means that another package management app (like apt-get or aptitude) is already running. Please close that app first." I click on the close button for this dialog
    "software index is broken, run synaptic"

    The computer crashes and goes to a text screen somewhere in this process, or if I just wait after booting up, it crashes anyway and goes to a screen dump. The only thing I can read that's intelligible to me is "modprobe tainted"

    I really need help getting my computer stable so I can use it again.

    Welcome to the Ubuntu Forums

    Have you removed the new trendnet wireless pc card?

    Are you you prepared to continue in the text screen, maybe with some help from the community?

    Do you remember or can you get the information from some error output, what is the offending package?

    You can run

    Code:
     sudo apt-get remove packagename
    to remove a package with the name 'packagename'.

    You can also try several commands one after another, but you must tell us where to start, to get instructions that fit your experience with the linux command line.

    Re: Computer crashes after bootup after attempting to install a wifi card

    Well, this is difficult reporting the screen dump because it doesn't appear that I can copy and paste the contents, put it on a memory card, transfer it to my wife's working computer to get online and post it. It also doesn't seem like I can print the screen to my printer. Print Screen doesn't seem to work. And my computer crashes long before I'm able to go online. Is there a way to create a report file/copy a report file from the screen dump when my computer crashes? Maybe I could copy a file to a usb device before crashing, that would make this a lot easier than typing it all in by reading the screen and retyping everything here. But I can do that if there isn't a faster way. Any ideas?

    Re: Computer crashes after bootup after attempting to install a wifi card

    Ok, I managed to copy these files from /var/log onto my usb memory stick right before crashing again. What is the most useful for troubleshooting? I can now copy and paste any of this information from this computer.
    dpkg.log
    syslog
    Xorg.0.log
    auth.log
    kern.log
    pm-powersave.log
    wtmp
    udev
    dmesg
    boot.log
    Xorg.0.log.old
    dmesg.0
    dmesg.1.gz

    I'm not good at reading log files. I hope someone who knows what to look for is reading this and can help solve this problem.

    -o-

    Have you removed the new trendnet wireless pc card?

    Can you boot from an Ubuntu install CD/DVD/USB drive (boot a live session without installing anything)?

    Re: Computer crashes after bootup after attempting to install a wifi card

    Yes, I pulled that card out as soon as I realized it wasn't going to work. I don't have a cd or dvd writer, and I saw on the forums that I might be able to boot to a usb drive, so I bought a new flash drive, downloaded the iso file and made it bootable. I changed my bios to boot from it, but for some reason I could not boot from it.

    I am sorry for not knowing exactly what to give you for information. I'm not new to computers, but my skills are probably dangerous, and I'm completely new to Linux. I got this laptop second hand and it already had Ubuntu Linux on it. I upgraded it to 12.04 about a month or so ago and it seemed to be going fine until I tried to install this ndis-wrapper and wifi card (sorry I mispoke before, stating "win-wrapper") Anyway, I don't understand Linux yet, and I'm sure I created this problem by not understanding what I was doing, trying to follow posted information to install that card, and to fix my problem once it started, so I hope you have patience. I'll try to provide whatever I can to help someone help me. Thanks in advance!

    This sounds suspicious. You haven't mentioned your system yet and should add system information (If I didn't miss this). You should also add if your laptop has only Ubuntu installed, or if you dual boot (using Grub? Grub2?).

    While I (fortunately) have not yet had to deal with UEFI boots under Ubuntu (or Windows, for the matter), failing to boot a live USB sounds as if you work maybe under a UEFI motherboard, using a pre-UEFI bootable USB. In this case, I just know that there are issues, and steps to take first. Here is a sample link about what to do, which doesn't necessarily help you: http://ubuntuforums.org/showthread.php?t=2111720. You should then also consider to read the wikipedia entry about UEFI. I think before you do anything else, you'll need clarity about this, and get the live USB to work because if you can't even do that, installing/uninstalling drivers and hardware is going to be a challenge. As I haven't had to deal with such issues, I won't be of any help, but you might update the name of your post to reflect the issue more precisely (If that's possible? I think it is - if not, consider asking a different question such as "Getting Ubuntu live USB to work on UEFI motherboard for (insert name and precise model of your computer)."

    Good luck!

    Re: Computer crashes after bootup after attempting to install a wifi card

    @ John,

    It appears from your first post that perhaps you happened to have an update offered when you momentarily had connection. There was an installation in progress and you restarted it prematurely, causing the package-manager lock "Open". However, that should not cause the crashing issue.

    I suspect that maybe you had a graphics driver being installed when you restarted. Either that driver wasn't properly installed or is having other issues (graphics drivers are the most common reasons for system crashes, but are not the only reasons).

    When the system starts to boot (at the purple splash screen), can you access the grub menu by pressing a key (shift or Esc perhaps)? If you can, try booting into "recovery mode" (the second option in the grub menu). If you can boot into recovery mode (gui or text only, whatever possible), we can attempt to find the cause and cure it. Otherwise, I'm afraid your only 'sane' option is to just do a re-install.

    Re: Computer crashes after bootup after attempting to install a wifi card

    I did a little more research and found commands to get computer information from the recovery bootup prompt. When I have more time tonight I'll retype the screen dump information from when my computer crashes. And yes, I did respond to a prompt to upgrade to 12.04 and said, why not? After I did so I did have some screen glitches but have been booting into Ubuntu 2d and haven't had any problems until trying to install this wifi card. I'm not trying to be suspicious about this. It's technically challenging for me and frustrating to figure out how to get the information needed to get to the bottom of this:
