This is my first time to install Ubuntu version is 14.04 desktop.   After installation on a virtual machine (Hyper V), It says to restart.  IT will stop at:  stopping early crypto disks      ok  Then it will stop here and it seems I have to shutdown the virtual machine to restart Ubuntu.   I am not sure if my installation is complete or not.  Thanks for any help.

I created a virtual machine to install ubuntu 14.04 on VirtualBox 4.2.12.*. I created virtual CD to install it with fixed-size virtual disk of 200GB. After successful installation, it restarted as usual. But after showing message of below, it hangs. Actually, I created virtual machines to install ubuntu at Virtual Box successfully several times. It's very easy. The installed ubuntu versions ranged from 9.10, 13.04 and even 14.04 before. I don't know why this time it hangs at restarting after successful installation. The only difference between this failure restart and previous successful ones is that the virtual disk is much larger, 200GB. It failed three times.  * Deactivating swap... [OK] * Stopping remaining crypto disks... [OK] * Stopping early drypto disks... [OK]

I want to use VirtualBox but it is giving me the error VT-x/AMD-V hardware acceleration is not available on your system. And in the virtual box settings, I am not able to open accelerator tab as it's frozen:    Please give me a step-by=step guide on how to fix this.

These two nice SE posts  comment on restarting one's ubuntu machine but they leave me with a few questions:   How do you actually do the restart (I'm a beginner and using 12.04.1 LTS)? Should I always restart the system when prompted to? Does restarting the system affect access to it via SSH or there any other caveats one needs to think about before doing this?

I installed Ubuntu 18.04 amd64 desktop on Asus Eeepc 1015px, but it hangs on booting. The last message is 'Started User Manager for UID 120'.  I managed to boot up in recovery mode and finished the installation with 'sudo apt-get upgrade', but nothing has changed.  Does anybody know how I can tackle it?  Thanks in advance, Newton.

My friend has been using ubuntu 10.10 on vmware player for many days now. But today, it has a problem booting, so we started the ubuntu live cd to try and fix it.  Running sudo fsck /dev/sda1 (got from ) says that the device or resouce busy. So, I'm guessing the partition was not unmounted correctly on the last shutdown for some reason.  Any help on how to fix the problem would be appreciated. If you need any further information, please provide the command to get it, as we have little knowledge of that.  Thanks.

Is it better to install Ubuntu completely new or is the upgrade process just as good? In other words, will my computer run just as problem-free and efficiently when I upgrade as opposed to a fresh install?

When I issue the following:  sudo shutdown now   ..my newly commissioned Ubuntu 14.04 server doesn't shut down. It stops with the following message:  * Stopping System V runlevel compatibility Give root password for maintenance: (or type Control-D to continue):   If I type in the root password, the machine simply sits there at the shell prompt.

I'm having some problems getting Ubuntu to install. I'm running Windows XP Home (32bit) on an older Dell Dimension 2350 with 1GB ram, trying to install either Ubuntu 12.04 LTS (32Bit) or 13.04 (32Bit) inside VirtualBox. Both versions of Ubuntu don't make it past the purple screen with the loading dots. When I change over to the "non-graphical" version, with the scrolling text, it starts to list a series of tests that are either [ok] or [fail]. There are only a few that fail, and my search on those indicates that they're not that important. There are a few settings for this VM that I've tried tweaking based on other searches for an answer (such as Enabling IO APIC, switching the Chipset to ICH9, changing the Video Memory size, Enabling 3D Acceleration, and Enabling PAE/NX. More or less, I get to the same point.  (Once I got to the screen with Desktop in the upper left corner, and the red-ish background. But an error came up that basically said there was an error, and that I could send off a report or hit cancel. I hit cancel, and instead of the installer coming up, nothing happened)  The last check that is run is "Stopping System V runlevel compatibility [ok], and a bunch of Starting [ok]s. Then I get a black screen, then a half purple half black screen graphical error. Sorta looks like snow, I don't know how else to describe it. After a while. That goes away and is replaced by a black screen again. Nothing else happens.    I like to think I'm fairly good at solving problems and following instructions, but I don't even know how to go about diagnosing this. Most of the solutions I've seen seem to involve entering things into a command line, but doesn't the OS have to be installed to be able to do that?  This is a for fun/learning experience project, so it's nothing too pertinent. But I would like to figure this out.

Why is it sometimes that I need to restart my computer after installing new software and at other times I don't?  Is there any reason why it needs this reboot or why it's not always one way or the other?

I was trying to install Ubuntu 12.04 in VirtualBox 4.2.12r84980. I see    this kernel requires an x86-64 CPU, but only detects an i686 CPU, unable to boot   But I am using a 64 bit Windows 8, and trying same .iso for trying Ubuntu. Then what is the problem?

My Ubuntu 16.04 hangs on shutdown/restart requiring me to press and hold the power key to turn the machine off... I don't know how to report this as a bug and what commands to run to show the necessary hardware/sys log info? Any help would be hugely appreciated!

I wonder if someone can help me? I am fairly new to trying to actually understand and use computers myself rather than just buying whatever Windows/Mac wants me to! You will get a giggle from my flawed attempts anyway :-)  I would like to start using Ubuntu on my PC, just got a new harddrive and did have a borrowed windows 7 disk as was planning to temporarily install it so i could get ubuntu. However I didn't have high enough spec hardware for win 7 (I think it is due to only 1gb ram, i do have 64 bit technology and a 1tb harddrive). I am quite happy to install 32 bit ubuntu and hear it is easier the use than 64 anyway.  So I have one other rubbish mini laptop (windows xp) which i am trying to use to get ubuntu onto a usb (laptop has no cd drive) so i can install it on the pc. First tried just downloading ubuntu 13.04 desktop onto a usb and trying to boot the pc from it which gave the message 'no operating system'. Then I tried this to create a bootable usb which sounded promising:  . However then it starting asking for my saucy desktop iso in order to install it onto the usb stick, can't really manage to find out what a saucy desktopp iso is, maybe a mirror image of an operating system, no idea why i would need that.  So in short, I'm lost. All I can think of is getting windows xp somewhere so i can get my pc to work and install ubuntu from the internet on that, or going to a friends house in the hope that creating a bootable cd is easier than creating a usb.  Sorry for my general ineptness and hope someone can help!

My host is x64 bits Windows 8.1.  I downloaded the latest Virtual Box (4.3) and I'm trying to create a VM with a 64 bits Ubuntu OS (ubuntu-12.04.3-desktop-amd64).  When I go to New VM wizard, it doesn't give me option to select "Ubuntu (x64)" as I have seen in other people's screenshots, only just "Ubuntu". As a result, the ISO can't boot. I tried in another PC and Virtual Box gives the x64 variants to most listed OS...  Control Panel shows x64 OS, x64 processor. My host laptop is a Sony Vaio VPCZ22UGX/N, Intel® Core™ i7-2640M processor. CPUz shows Vx-t is available on my processor, of course.  Here is what I tried so far:   I enabled IO APIC as required in the docs. I have virtualization enabled in the BIOS. It works fine in VMware. Check that Hyper-V is not running or even installed on my Windows. Same for VMware. I also tried running the command:  VBoxManage modifyvm [vmname] --longmode on    for that VM, but no change.. I think the issue is really that I can't select x64 variant of the Ubuntu OS for that VM. Other people seem to indicate that's a requirement, but I don't get that option for some reason.  I spent a lot of time and can't find what's wrong... Anyone knows what could be missing here?  Thank you very much!!  Eduardo

Inside a VirtualBox VM, I have installed myself an Ubuntu 16.04.1 LTS Server installation. However, when I installed the ubuntu-desktop package and rebooted, this happened:    Exact command I used: sudo apt-get update; sudo apt-get install ubuntu-desktop ..and then a reboot command.  This just seems like a corrupted top-left portion of the screen, as my cursor can appear in view (but corrupted):    This is a purely graphical issue because I can use the keyboard to successfully progress to a desktop:    Note: On startup it shows correct graphics for a split-second then reverts to glitch.    Any help on this?

I downloaded and installed Ubuntu from the official site. However, I don't know if I installed the 32-bit or 64-bit version.  In Windows 7 I could right click My Computer and it listed which version it was.  Is there an easy way to check in Ubuntu?
