Being a Debian user, I always like to experiment with the latest packages, and so I have many third party debian repositories listed in the sources.list file. Whenever I am adding it for the first time, I usually get the error:

“The following signatures couldn’t be verified because the public key is not available”

On googling multiple solutions can be found to add a public key using apt-key, but most of them has 3 or 4 commands, including downloading the key, move it to a file and then import. But the one line command that does the same is as below:

apt-key adv --keyserver keyserver_url --recv-keys key_id

My laptop, HP NC6220 is confirmed dead. Its issue with display repeats after 3 days of servicing and the service engineers couldn’t rectify it permanently. So, they agreed to give a refund and I am forced to buy a Laptop. Thanks to the financial support by parents, I bought a Lenovo Thinkpad Edge E430 (3254 AM4) yesterday. Special thanks to my cousin Prakash for arranging it at the lowest rate possible.

I also bought a Lenovo G580 7036 for my friend Deepak and spent most of the time, yesterday configuring it. Will post a review of that asap.

So, I have used the thinkpad for just few hours and here goes my experience with it.

The basic configuration of the system is:

Intel Core I3 2330M – 2.20GHz
2GB DDR3 RAM
500GB HDD (7000 RPM)
14″ HD Antiglare Screen
DVD Writer
720p Webcam
Card Reader
Finger Print Reader
4 USB ports (2 with USB 3 support)
