I decide to downgrade kernel version due to unsolvable problem with wifi. Ubuntu version is 12.10, kernel version is 3.5.

In http://packages.ubuntu.com/precise/kernel/ I found the previous kernel version 3.2. I decided to install linux-image-3.2.0-51-generic. The question is it enough to install just linux-image package, do I need to install linux-header package too, are there more package I should install?

The second question, as it suggested on the website, the right way to install the packages is to edit the file /etc/apt/sources.list insert the line deb http://security.ubuntu.com/ubuntu precise-security main. However after inserting and running the update I still cannot find packages of linux-image 3.2 by apt-cache search linux-images*. Where I am wrong?

  • @amc, thank you for the comment, the main question what the *image-header* package for, and should I install it? And how to make the downgrade from repository? I don't find answers on these question in the question your mentioned. – user10756 Aug 12 '13 at 08:03

On spelling. The correct command is 

apt-cache policy linux-image-*

Also, the Tab Completion feature is very handy and you should learn to use it. Open a terminal and write 

 sudo apt-get install linux-image-

Then hit Tab key twice and read the list, can you see 3.2 kernel ?

do I need to install linux-header package too, are there more package I should install?

Every linux-image has its own linux-headers version, so it is preferable to install them too. 

sudo apt-get install linux-headers-

and use the same Tab Completion feature (as in linux-image- above) to locate the appropriate ones.
