How to Install Puppylinux on USB Drive

Puppylinux is very easy to install on USB Drive. Puppylinux has USB universal installer that lets you install the distro on the USB drive. But if you follow the official help or FAQ then they expect you to burn a CD in order to use that feature.
What if you don’t have a CD Burner or disc to burn puppy linux? We’re going to solve this problem in this tutorial.

First download the latest puppylinux .iso file from the official puppylinux archive or respositories. Once you do that you can go ahead and do the checksum in order to see if the .iso is properly downloaded.

Second step is to download UNetbootin software from your distros repository. If you’re runing ubuntu linux then find the Unetbootin in software center. You can download and install it and later find it in System tools section menu.

Open the Unetbootin and then choose the distro name and version. You can also download distros from this window but it is always better to download with torrent or another download manager instead of this software. Now just point the software to the .iso file and select the USB drive. You can click Ok once you do the settings. After setting up you’ll find that Unetbootin takes few minutes to burn the distro on USB drive.

Once you’re done with installation on USB drive. You can reboot from the USB drive in BIOS and boot into Puppylinux. This is very easy method to install the puppylinux on USB disk.

How to Install Themes in Cinnamon Desktop

In this tutorial you’ll learn how to install cinnamon themes. I am assuming that you have installed the cinnamon via PPA or your distro installed it by default. In any case, lets get to install the themes for cinnamon.

If you have not downloaded the cinnamon themes before, I suggest you to download the themes. Once you download the themes on your desktop, you can install them by following any one of these methods.

• Method 1: Make a .themes directory in your home directory and paste the extracted theme files there.
• Method 2: Copy the contents of the extracted folder and paste it using sudo in terminal.   sudo cp -R theme /usr/share/themes
• Method 3: You can open the file manager like nautilus or thunar in sudo and then copy the contents to that respective folder.

You can now change the themes using the cinnamon settings program which is included in cinnamon desktop. This program allows you to set and deactivate the GTK+ themes.

You can download the cinnamon tested themes from the spices website or you can download the gtk themes from gnome-look.org or deviant art website.

Please note that some of the themes may or may not work based on the version of GTK themes. So please doublecheck the sources from which you’re downloading the themes.

How to Solve : The following signatures couldn't be verified because the public key is not available: NO_PUBKEY

When you type in the apt-get update and get the NO_PUBKEY error then make sure that you copy the error number mentioned after the word NO_PUBKEY.

Once you copied that number you can use it along with following command to get gpg key from launchpad to fix that.

For example,

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 61E5F6C15F6C1

Do execute the following command,

sudo-apt get update

as many times as the error occurs and then go ahead with the previous steps to import the GPG key. Once you get the errors resolved by importing the error key, you can do normal apt-get update.

Thats it, after importing the GPG for each error key, you can get the solution.
