How to Create Windows 10 Bootable USB on Ubuntu or any Linux desktop

Are you looking for any desktop application on Ubuntu to create a bootable pendrive/flash drive with Windows.

WoeUSB is a simple tool that enable you to create your own usb stick windows installer from an iso image or a real DVD.

WoeUSB package contains two programs:

woeusb: A command-line utility that enables you to create your own bootable Windows installation USB storage device from an existing Windows Installation disc or disk image
woeusbgui: A GUI wrapper of woeusb based on WxWidgets

So, lets know how install the WoeUSB on Ubuntu
Official & updated Installation and Github link : Here

#    sudo add-apt-repository ppa:nilarimogard/webupd8

#    sudo apt update

#    sudo apt install woeusb

In case if you wish to remove that woeusb PPA, remove it from the bellow command.


#    sudo add-apt-repository --remove ppa:nilarimogard/webupd8

#    sudo apt-update

Now, WoeUSB has installed on my Ubuntu, though the interface is self explanatory still let's move ahead and know how to use it.

Open WoeUSB application and choose the USB drive and your windows iso kept within your Ubuntu.

Once you are done click install and you are done, you can monitor the progress on screen.

In case you receive a error dialogue like below, follow the below steps

Find your USB drive's mounted file system and block by running lsblk on terminal and find your device their.

To filter, look for size of your USB or name of the USB drive, below screen shot gives the picture of my USB drive ( 8 GB ) size, and named as /dev/sdc


#    lsblk

So we will unmount that partition out of the system.

Notice there /dev/sdc is the full size of my USB disk, but the data is witten on it's /dev/sdc1 partition.

My USB disk is /dev/sdc, ensure your USB is unmounted with the following command. Replace /dev/sdc1 with your own partition name.


#    sudo umount /dev/sdc1

Now try again from the WoeUSB desktop application.

In case if you are willing to do the same through woeusb CLI utility, here is the way.


#    sudo woeusb -v --device /home/kunal/windows-10.iso /dev/sdc

/home/kunal/windows-10.iso : Replace it with your iso location.
/dev/sdc : replace it with your USB drive ( check it from lsblk )

How to Upgrade Ubuntu 16.04 to Ubuntu 18.04

For Linux Desktop users, this is the trending stuff all going into the Linux World.
Of Course there are a hundreds of Linux distros, but Ubuntu is one of the popular one as per distrowatch.

Ubuntu provids two types of releases

Standard release.
Long Term Support (LTS) release.

So what's the difference between these two ?
All it's support provided by Ubuntu aka Canonical
Standard releases for approx 1 year while Long Term Support is useful for approx 5 years.

Ubuntu 18.04 is an LTS release will be supported till 2023.

If you are also a Ubuntu Desktop Fan and running Ubuntu 16.04, why wait let's upgrade.

But if you are running ubuntu 16.04 within your server, i recommend you to wait for a minimum of two months from release date.

Backup your data first.

We strongly recommended to backup all your important data from your Desktop to a remote location or into some external storage.

Update all your system packages.

sudo apt-get update
sudo apt-get upgrade

Install Update Manager

sudo apt-get get install update-manager-core

Once the update-core-manager package has been installed, let's ensure it's config file is set to LTS

Open the file /etc/update-manager/release-upgrades file and make sure Prompt value is set to lts like below.

Prompt=lts

Upgrade your Ubuntu from 16.04 to 18.04

Once you are done with the updation of file /etc/update-manager/release-upgrades updation , you are all set to upgrade your UBuntu to newer version of LTS that is 18.04.

sudo do-release-upgrade -d

Once you have executed the upgrade command, you must stick to your computer for some more few minutes.
It will ask for few inputs from your side, follow the prompts and choose the default ones, the entire upgrade time duration is totally dependent on your internet connectivity speed.

Once completed, reboot your System and verify your Ubuntu Version.

lsb_release -a

You must see something like below

Distributor ID: Ubuntu
Description: Ubuntu 18.04 LTS
Release: 18.04
Codename: bionic

Ubuntu: Stop pdf to open with default ImageMagick

Surprisingly after migrating from Unity to Cinnamon DE, i found a very annoying and strange behaviour or my default application for PDF .

Instead of Document Viewer, it's using ImageMagick to open each PDF document, though i have adobe reader within my Ununtu 16.04, but it's not ready to leave ImageMagick at all.

So now , as always our friend is Terminal, follow the below steps to get rid of ImageMagick.

edit the file ~/.config/mimeapps.list

Now remove the lines that associates PDF to imagemagick in the file:

image/pdf=display-im6.desktop
image/pdf=display-im6.q16.desktop;display-im6.desktop;

I have performed these steps within my Ubuntu 16.04, hope this gonna work for you too.

Ubuntu : Touchpad and right click not working on Lenovo ideapad 320-15ISK

So these are the problems I encountered after a fresh Ubuntu 16.04 installation on my new Lenovo ideapad 320-15ISK.

Strange confusion between right and left click ( functioning opposite ).
Couldn't drag any window from touchpad.
Right click not working..seems to be disabled.

So below is the code snippet that work like a charm for me.

Do open the below file from terminal.

cyberkeeda@Linux-Maniac:~$ gedit /usr/share/X11/xorg.conf.d/51-synaptics-quirks.conf

Copy paste the below snippet at the top of the file.

Section "InputClass"
    Identifier "touchpad catchall"
    Driver "synaptics"
    MatchIsTouchpad "on"
    MatchDevicePath "/dev/input/event*"
    Option "TapButton1" "1"
    Option "TapButton2" "2"
    Option "TapButton3" "3"
    Option "ClickPad" "true"
    Option "EmulateMidButtonTime" "0"
    Option "SoftButtonAreas" "50% 0 82% 0 0 0 0 0"
EndSection

Save and restart your system, hopefully everything must work now.

Cinnamon desktop shows double desktop icon.

To fix it, do run the following commands.

cybeerkeeda@Linux-Maniac:~ sudo gsettings set org.gnome.desktop.background show-desktop-icons false

ShellinaBox Installation on CentOS7

Introduction [ Shell In A Box ]

Shell In A Box implements a web server that can export arbitrary command line tools to a web based terminal emulator. This emulator is accessible to any JavaScript and CSS enabled web browser and does not require any additional browser plugins.

Official repository link

More info on official git page : https://github.com/shellinabox/shellinabox

Installation.

l Intsall EPEL Repo.

[root@cyberkeeda ~]# yum install epel-release

l Install shellinabox package

[root@cyberkeeda ~]# yum install shellinabox

Configuration.

Shellinabox configuration file : /etc/sysconfig/shellinaboxd

Lets have a look on the file and allow and modify the important lines

[root@cyberkeeda ~]# vim /etc/sysconfig/shellinaboxd

# Shell in a box daemon configuration

# For details see shellinaboxd man page

# Basic options

USER=shellinabox

GROUP=shellinabox

CERTDIR=/var/lib/shellinabox

PORT=4200

OPTS="--disable-ssl-menu -s /:LOGIN"

OPTS="-t -s /:SSH:192.168.0.181"

l PORT

PORT=4200

Chnage PORT to some other to avoid conflict between sytem level ports

I will be changing it to 6162

l SSH HOST

OPTS="-t -s /:SSH:192.168.0.101"

Chnage IP or Hostname to your default login host, by default shellinabox will ask to login into it, then later you can ssh and jump into n number of servers.

My final config file would look as

# Shell in a box daemon configuration

# For details see shellinaboxd man page

# Basic options

USER=shellinabox

GROUP=shellinabox

CERTDIR=/var/lib/shellinabox

PORT=6162

OPTS="--disable-ssl-menu -s /:LOGIN"

OPTS="-t -s /:SSH:192.168.0.101"

Configuration Done..

Important :

STOP Firewalld iptables and disable selinux

# Service firewalld stop

# Service iptables stop

Disable SELINUX : change status of selinux to disabled

Finally Restart the shellinaboxd daemon.

[root@cyberkeeda ~]# service shellinaboxd start
