Full Version: Kernel question on when to update
You're currently viewing a stripped down version of our content. View the full version with proper formatting.
When I was running Netrunner rolling it had a neat kernel tool and I was always able to tell what I was running or should be running and what was LTS.   (I have no reason to run anything other than LTS!)

I'm currently running

Quote:$ uname -r
4.4.0-47-generic

...and update manager (see screenshot attached) is listing an kernel update: it says "security update)" but it is a level five update and in the preferences, a level description for 5 is: "Dangerous update.  Known to affect stability..." etc etc.

Should I install? Please educate me.
Thanks!
It is an LTS kerne update. You can update it. By default the kernel will be installed alongside so you can boot the old one if anything goes wrong.
Level 5 only indicates that this is an update that might break your experience.
While we're on the subject, how does Maui Linux get rid of the older kernels after updating?

I can understand having the previous one hanging around after an update, but if I end up with several, should I have concerns?  Should I delete older ones, and how might I do that?

(be nice, I'm still getting used to Linux  Blush )

Thanks.
Yes you need to remove them manually via apt-get or synaptic.

Thanks!
dpkg -l | grep linux-image

That will give you kernels installed.

Mine looks like this....

i linux-image-4.4.0-51-generic 4.4.0-51.72 amd64 Linux kernel image for version 4.4.0 on 64 bit x86 SMP
ii linux-image-4.4.0-53-generic 4.4.0-53.74 amd64 Linux kernel image for version 4.4.0 on 64 bit x86 SMP
ii linux-image-4.4.0-57-generic 4.4.0-57.78 amd64 Linux kernel image for version 4.4.0 on 64 bit x86 SMP
ii linux-image-extra-4.4.0-51-generic 4.4.0-51.72 amd64 Linux kernel extra modules for version 4.4.0 on 64 bit x86 SMP
ii linux-image-extra-4.4.0-53-generic 4.4.0-53.74 amd64 Linux kernel extra modules for version 4.4.0 on 64 bit x86 SMP
ii linux-image-extra-4.4.0-57-generic 4.4.0-57.78 amd64 Linux kernel extra modules for version 4.4.0 on 64 bit x86 SMP
ii linux-image-generic 4.4.0.57.60 amd64 Generic Linux kernel image

As you can see I have 3 installed. I like to keep 2 so I would in a terminal

sudo apt --purge remove linux-image-4.4.0-51-generic linux-image-extra-4.4.0-51-generic

Hope that helps.
Yep, that looks about right to me. However, I'm not sure purge is necessary though.
Alternatively, for those who prefer to do it graphically:
