This is how I do it. Mileage may very, use at own risk. First: sudo apt-get install linux-image- This will give you all current options for a new linux kernel image. Next do the same with the headers! sudo apt-get install linux-headers- Make sure you do your headers too!!!

So I need to unrar password protected files that are in a batch. Apprx 10-20 each time. This little command line script worked wonders for me, just replace PASSWORD with your password. find -type f -name ‘*.rar’ -exec unrar -pPASSWORD x {} \;
