UKUU (Ubuntu Kernel Update Utility) is a tool to update the kernel of your Ubuntu distribution in an easy, intuitive way and from a graphical interface. Although the updates that Canonical provides for Ubuntu periodically update the Linux version automatically, it is always interesting to know other methods to be able to install more updated versions or specific versions that we have available for the distro.
From ukuu we can manage the kernel versions that we are going to install or remove from our distro without the need for high computer skills and with a simple GUI. Sometimes, installing a new kernel becomes a complicated task for newbies and they tend to have some qualms about doing it in case something does not go well, but with this type of tool it will allow us to do it in a much safer way for users without advanced knowledge.
For install ukuu and put it into operation you must follow the following steps:
sudo add-apt-repository ppa:teejee2008/ppa sudo apt-get update && sudo apt-get install ukuu
We already have it installed, and now we can check it out consulting, for example, the version of the ukuu tool or directly opening the graphical app:
ukuu --version ukuu-gtk
You can launch the graphical tool from the terminal by running ukuu-gtk or find it in the app launcher, as you like. Once open, wait a moment for it to update its database from the Internet with the available kernel versions and once you have the list in the main window, you can select the version you want to install from the list and press the Install button. Then you just have to wait for the procedure to finish and you can restart the system to see that everything is OK with the new kernel.
Beware of removing old kernels before checking that the new one is 100% functional! Otherwise, we would be left with a system that cannot boot. On the other hand, having a previous version that we have been using and we know that it works, we can always start with it so that everything works if the new one is not right ...
