running 17.04

i get this error for a normal apt-get upgrade:

[SOLVED] Trouble booting Windows 8 after Ubuntu 16.04

August 31, 2017, 7:48 pm

I installed Ubuntu on a Windows 8 system that had about half the SSD available. I used the option that simply installs Ubuntu along side Windows without me specifying any changes to the partition table. I can boot into Ubuntu just fine, but not Windows. I think Grub can't find windows. I only have four options at boot:

Ubuntu
Advanced something Ubutnu
Windows boot manager
System something

When I try Windows boot manager, I just get an Ubuntu-purple screen. I tried reinstalling Grub2 from the Ubuntu USB, but I got an error saying the file system i chose wasn't bootable.

Can anyone give me some guidance on what to do from here?

sudo fdisk -l

I have been unable to boot and install Ubuntu onto my computer from a USB stick. I have an ASUS G75VW. It runs windows 10. I downloaded Ubuntu and used Rufus to put it on a USB as a bootable USB. The problem is when I restart my computer and go to the UEFI/BIOS, there is no option to boot from the USB.

[ubuntu] About This Computer Always Says "Install Updates" Even After Updating

When I select the upper right menu, "About This Computer", the panel always comes up with the button in the lower right saying "Install Updates". Even after I click "Install Updates", and it checks, it says "The software on this computer is up to date". But it never changes the button in "About This Computer" to "Up to Date" like it used to. Ubuntu 16.04 LTS.

I've been running Ubuntu for 9 years on another computer (which is now 16.04 LTS as well), and I've never seen this behavior before.

[ubuntu] Not able to install Ubuntu 17.04 on hard disk

Hi,
I’m trying to install on one of my hard disk, Ubuntu 17.04 Desktop, using an iso image « ubuntu-17.04-desktop-amd64.iso » (downloaded from « https://www.ubuntu.com/download/desk...itecture=amd64 »).


I use the same way as usual, loading the iso image on an usb key with « netbootin » and booting my system from the usb key using and instruction in the Bios. I have used this process in the past for many times without any problem. With the 17.04 version, the system start with the « Ubuntu ... » signal in the middle of the screen and after, nothing happens! The system seems to be freezed.


My global configuration is multi-boot and I use Grub2 to manage wich system I’m using. I have also tried to boot directly from Grub2 and the iso image as described on the Ubuntu documentation (in french : https://doc.ubuntu-fr.org/tutoriel/g...des_images_iso). The result was similar as what the usb produce.


I have tried to use the iso image with Virtualbox and the system load correctly all seems to run properly.


Is there somebody that can give me an idea where I can look to find the source of the problem!!!


Thanks in advance!

Hi,

I had 16.04LTS running OK on an old Dell Inspiron 1520 laptop but I some kind of failure when installing software (including I think OS) updates, power may have failed during this (not sure as pc was unattended).

Unfortunately now it gets stuck in boot up process. I get a few screens of technical text running quickly by so I can't read it, the last line says

Code:
[0.477393] ---[ end Kernel panic - not syncing: VFS: Unable to mount root fs on unkonwn-block(0,0)
Is there any way to repair or restore the installation without having to just reinstall everything from scratch?


Many thanks

[ubuntu] removing package from synaptic package manager

  1. I've added a PPA to get the version of a media player I want
  2. I installed the media player and realized that it has a bug
  3. I removed the PPA by deleting the reference in /etc/apt/sources.list.d
  4. I then used the the package manager to completely remove the package
  5. When I search for the media player in the package manager, it still shows up. This prevents me from installing another version of this player


How can I remove all references to this package?

Thanks

I have just upgraded my netbook Dell Inspiron mini 1012 to Ubuntu 16.04 and I cannot boot normally. The only possibility to boot is in advanced options: kernel (upstart). In the other options the boot freezes and I have to shut down the power to boot with the startup advanced option.

Hello folks,
I've obtained a new pc (weeeh!) and wanted to dual boot with the windows version it came with (win7,home).
So I created a bootable usb with rufus.
Installation was succesful, it was SUPPOSED to have created a seperate partition.
Unfortunately, now theGrub only lists Ubuntu.
And I'm a noobuntu, so its no fun.
Any ways to "revert"or roll back the install? Thanks..

[ubuntu] Problem with UEFI install on Dell Tower - boot-repair does not fix

Whe I first tired to install ubuntu on my new DELL XPS 8920 tower the SSD drive was not showing up as an option.

I figured out I had to enable the UEFI boot in the bios -- then I could see the drive, and was able to install 17.10 on the SSD drive /dev/nvme0n1p1.

When I rebooted it worked great for several weeks - but after installing some updates and rebooting I am unable to get the boot loader to start grub.

I tried booting to live cd off of USB stick and installing and running boot-repair but it did not solve problem.

Here is the paste bin output from boot-repair: http://paste.ubuntu.com/25453270/

I don't care about /dev/sda -- that is a 1 TB drive I will use for data later.

Goal is to just get UBUNTU running from the SSD ( which was working )

Would be ok if I could just make a usb that would boot and let me add an entry to launch linux from the SSD.

Can anyone help me get this Dell bios to recognize and boot my uefi

FYI: I am running EFI with secure boot off.

[ubuntu] 17.04 Software Updater Doesn't Launch

Running 17.04 with kernel 4.10.9-32

The Software Updater does not launch when updates are available. The icon has turned green to indicate that updates are available.

When I click on the icon in the Unity Launcher nothing happens.

I have to reboot before I can launch the Software Updater. I get a "system problem" popup but that is for cupsd, which should be irrelevant.

What information should I collect to diagnose this problem?

Hi guys,


I installed Kubuntu Linux 17.04 in my Lenovo All-in-One. It has a UEFI system and, after installing Linux, it always starts Windows at startup and no bootloader is showed after power on.
I created an usb disk with Boot-repair-disk distribution and try to repair the boot, but nothing happens.
However, it created a report but i can't post it to the forum.

Can you help me?

PS: I disabled Secure Boot and Quick-Boot from BIOS settings

EDIT:

I Solved the problem disabling a BIOS settings for windows 8/10. Doing this, the boot options were unlocked and Now I can choose the Legacy Boot Mode that works with Linux.

[mythbuntu] Mythtv Totally Screwed Up After 'Upgrade' to 16.04

September 3, 2017, 12:24 pm

I just 'upgraded' from 14.04 to 16.04. I have a Hauppauge HVR-2255 video card which required a custom kernel supplied from Hauppauge. After the 'upgrade,' mythtv is useless. First off, when I try to play a recording, all I get is sound and mythtv disappears from the screen. The card is said to be supported in the 16.04 kernel but backendsetup -> capture cards doesn't even show any dvb devices.

So, I restarted with the old kernel. Running the backend setup started out with a lot of missing information. After deleting and adding cards and making connections, everything looks OK, but I still just get errors on all cards. When I quit, I get a message saying that card 10 (?) is set to start on a channel that doesn't exist. I have no idea where it's getting that information or why it thinks I have that many cards.

Am I wrong that the card should be supported? If I uninstall mythtv and reinstall it, how do I retain all my recording information? Is a reinstall likely to help?

Also, the frontend on my laptop running ubuntu 14.04 can't connect to the remote backend because of the 'upgraded' database. Can I upgrade the frontend on my laptop without 'upgrading' to 16.04?

Ubuntu hangs when installing plugins

I freshly installed Ubuntu 4.10.0-28-generic 64 bit. I installed it onto vmware Workstation 12 latest update. I then ran sudo apt-get to update the system. Then I ran sudo apt-get install codeblocks.

After that I noticed that the terminal window is hung with the following:

Master path of compiler ID "null" is empty -> triggers auto-detection.
ClassBrowser::UpdateClassBrowserView(): No active project available.
ClassBrowser::OnThreadEvent(): Updated class browser...
ClassBrowser::OnThreadEvent(): Class browser updated.
Compiler plugin nactivated
Debugger plugin activated
Loading toolbar...
Initializing plugins...

I did not kill the terminal because I'm not sure if it is in the middle of something that could cause more problems if interrupted.

Does anyone have a suggestion as to what I should do?
