I have downloaded kubuntu-17.04.1-desktop-amd64.iso  So on my terminal:  lsblk cd ~/Downloads sudo dd if=kubuntu-17.04-desktop-amd64.iso of=/dev/sda bs=4096   But it does not work. I use the same lines above to create flash drive for Kubuntu 16.10 and no problem at all.  Why?  Is kubuntu-17.04-desktop-amd64.iso that I downloaded corrupted?

Problem:  I created 3 DVD's filled with Windows system recovery disks in case I ever have a hardware problem and need to re-install Windows in order to run diagnostic tests.  However, I don't want to worry about losing them, so I would like to make backups of the recovery disks as ISO images which I can store on an external hard drive.  A Google search revealed that I can do this using the dd (or "disk dump") unix command.  dd if=/dev/who-knows-where? of=/home/wdkrnls/x201-recovery-2011-09-30.iso   But the snag is that Ubuntu doesn't use the old convention of associating /dev/cdrom with the cd-rom drive.  Instead Nautilus automagically creates /media/CD_ROM which is a directory, and not the drive itself.  I tried to run dd anyways and got:     /bin/dd: reading '/media/CD_ROM/': is a directory   0+0 records in   0+0 records out   0 bytes (0 B) copied, 0.0158501 s, 0.0 kB/s   I tried running dmesg | tail and saw a reference to:     [215135.134164] sr 9:0:0:0: Attached scsi generic sg1 type 5   So I tried ls /dev/sg1, but there wasn't any file called that.  Only my partitions show up with sudo fdisk -l, leaving me stumped as to what to try next.  Solution:  I figured out I could solve my problem with brasero or k3b and so abandoned my exploration of Ubuntu's internals.  Nevertheless, I still wouldn't mind knowing how I would use dd to accomplish the same task.  How would I solve my problem with dd?

I accidentally issued some commands I thought were safe in the terminal, and I ended up with no System Settings and lots of other missing functionality, but the OS still boots normally. I've decided I want to install Lubuntu instead of fixing Ubuntu for a fresh start and since my laptop is running on a 1GHz dual core AMD CPU.  I created a bootable USB as I usually do and placed Lubuntu 17.10 amd64 using Rufus 2.14.1086. I have GRUB that was installed with Ubuntu upon first install I still have Win8.1 which I still want to keep.  PS: I also tried creating a startup disk from Ubuntu  The question is: How can I boot from USB with GRUB2 so I can overwrite Ubuntu?

After upgrading from Kubuntu 20.04 to Kubuntu 20.10, I could not login as it just showed a black screen after boot. So I switched to command line and reinstalled Kubuntu desktop with sudo apt-get install --reinstall kubuntu-desktop kde-*. After that, i was able to login and can use all applications but the icons and background of input boxes of system apps have turned black as shown below  Notice the black squares at the bottom right in the system tray, they used to be icons for Volume, Network, Bluetooth, etc. I can however click them and they behave as they used to. Also the desktop apps' icons are black.  Notice the input fields at the right of Layout, Wallpaer type and also the button backgrounds of the window. After looking at some logs I noticed that Akonadi server was not starting up because of an unknown MySQL error and installed MariaDb as i read somewhere that it might help. Now I can start Akonadi server with akonadictl manually but still the same issue. I restarted plasma with kquitapp5 plasmashell &amp;&amp; kstart5 plasmashell but still same issue. Also Akonadi does not start automatically when session begins.

What I want is to create a bootable pen drive that shows GRUB menu and I can select any of the several bootable systems from there to install/run. I have several ISO images that I want to install in the USB like Ubuntu, Fedora, System Rescue CD, Windows XP and Windows 7 (The windows versions are optional, mostly am looking for a multi installer for Linux distros, specially Ubuntu version)  The default Startup Disk Creator only works with Linux Images and only 1 at a time (At least for the mean time. If it allows more systems and multiple ISOs it would be awesome)  What method exists that I can use step by step to create a bootable USB Drive with multiple images than can be booted from the USB and selected from GRUB. It must support Windows Images and Linux Images.  Alternatively, is there also a way to have multiple versions of the Ubuntu installation ISO on same USB Drive, such as, when booting from it, I get to choose what Ubuntu version and architecture to install, for example:     BOOT MENU   Ubuntu 12.04 32 Bit   Ubuntu 12.04 64 Bit   Ubuntu 12.10 32 Bit   Ubuntu 12.10 64 Bit   UPDATE: Wanted to add that the English version for the post mentioned by daithib8 is here:

I want to create a recovery flash drive. I have my 8 gb flash drive[Kingston data traveller] with me. I also have the required .iso files for a>Ubuntu 13.10 b>Boot-repair disk c>AVG Rescue CD  I Wish to create 4 partitions(3 for each bootable .iso and one for data storage. Also, I want a way in which I can select which OS to boot each time I boot from USB.   So, is there a way to install GRUB on USB as well as the three other live distros? And how to create such a setup?

I have a bootable pendrive containing Ubuntu GNOME 16.10 (amd64) on it, and I installed it on my pc with no problems. But when I tried installing it on a pc in my college, it said "failed to load ldlinux.c32". After a while, I found out that that pc was 32bit. Could this be the reason that the installation wasn't working?

I have tried to create UEFI bootable USB drive within Ubuntu 14.10 (Startup disk creator didn't help nor I am interested in using it.). I have formated USB with FAT32 and GPT. So the only thing left to do would be just to copy all files from ISO to USB. That method worked when it comes to Linux Mint 17.1 and Clonezilla live CD, but when I tried to create bootable USB for Ubuntu 14.04 or Kubuntu 15.04 beta 1 there was an error copying files. Actually, on several occasions (4 or 5) pop-up window appeared.   After ignoring this errors, both Ubuntu and Kubuntu USB boot-up just fine, with no apparent problems in Live mode.   Can someone please elaborate what this symbolic links presents? Will this cause some problem when OS is installed?

I am a newbie to all of this stuff.  Initially I had a OS CD of Ubuntu 10.4 version. I never tried to install it. Now I have lost my CD somewhere. Earlier I copied the content to my laptop. When I tried to install by copying to another CD/pendrive it didn't install.  Now i am using Windows. But I would like to install Ubuntu, because everyone said that Linux/Ubuntu is an amazing OS.  So I searched in google for a solution. With Unetbootin, pendrive linux, I can make a bootable pendrive to install. But Unetbootin asks for an ISO-image. I did many experiment and wastes more than 9 CD's. I have no experience with that. Where can I get the ISO-image? Actually, what is an ISO-image?
