How to unzip the password protected zip archive.

Today I received TDS Certificate pdf file from IDFC Bank which was inside password protected zip folder.

I could not extract the file on Ubuntu 16.04 and also on Windows 10.

Then I tried unzip command and got the following error:
unsupported compression method 99
After googling the error I learnt that I required latest version of p7zip-full(version 16.02) whereas the available version on Ubuntu 16.04 is 9.20.

I installed the latest version as follows:
sudo add-apt-repository ppa:jonathonf/backports
sudo apt-get update
sudo apt-get install p7zip-full
If you use Windows you can get latest p7zip from this link.

Now enjoying free data and voice calls upto 31st Dec 2016 as per Welcome Offer of Reliance Jio.
All Voice Calls on Reliance Jio Network are VoIP calls consuming Data. But after 31st Dec 2016 the Data consumed for Voice Calls is not going to be charged making the calls as free.

Playing Linux Desktop Audio on Chromecast.

I was using Chrome Browser to play Audio & Video from my Linux Desktop to Chromecast through Chrome applications.

I learnt about mkchromecast and installed it on Debian Testing which is my alternative to Ubuntu 16.04.

After installing the .deb package I had to install the dependencies through apt-get install -f install command.

I opened VLC and started playing my favourite music.

I had to run mkchromecast through terminal and it got connected to Chromecast and asked me to open pavucontrol and change the sink to mkchromecast.

Removing old kernels on Ubuntu.

On Linux distributions you get kernel update and the images of old kernels remain on your machine occupying space. I got a kernel update today:
$ uname -r
After restart I could see that the image of old kernel was present on the machine:
$ dpkg -l | tail -n +6 | grep -E 'linux-image-[0-9]+' | grep -Fv $(uname -r)
ii  linux-image-4.4.0-24-generic                4.4.0-24.43                                         amd64        Linux kernel image for version 4.4.0 on 64 bit x86 SMP
I removed the old kernel by using following commands one by one:

sudo dpkg --purge linux-signed-image-4.4.0-24-generic
sudo dpkg --purge linux-image-extra-4.4.0-24-generic
sudo dpkg --purge linux-image-4.4.0-24-generic
I removed the kernel headers by using following commands one by one:
sudo dpkg --purge linux-headers-4.4.0-24-generic
sudo dpkg --purge linux-headers-4.4.0-24
Since I remove the previous image on every kernel update I had to remove only 4.4.0-24 but if you are doing it first time you may have many images starting from

TintCore Linux on Lenovo G50-45

About 8 years ago I tried TinyCore Linux and developed a couple of tcz files to the project.

Yesterday I downloaded the latest TinyCorePure64-7.1 ISO and made a UEFI bootable USB stick to try it. I could boot to the desktop and connect through wired network (wireless wlan0 was not detected out of the box but that was expected from the Tiny Linux distribution). I installed Opera Browser.
After searching on the Forums, I installed following tcz files:
After this wlan0 was detected but I had to make wpa_configure.conf file and connect through following command:
$ sudo wpa_supplicant -iwlan0 -c/opt/wpa_configure.conf &
I have added the above command to /opt/ to automatically connect on next boot.

Now I can explore this Tiny Linux distribution once again.

Running Ubuntu 16.04 Xenial Xerus on my Lenovo G50-45 Laptop.

I had downloaded Ubuntu 16.04 Daily ISO and was periodically updating it using zsync. I updated it this morning to version 20-Apr-2016 22:30 and assuming it that it is going to be the Final version installed it to hard disk replacing Ubuntu 14.04.4 Trusty (which I was not using anyway).

See the screen shot below with Unity Launcher moved to Bottom using Unity Tweak Tool (which is now available in Software).
