Should I update the kernel?

Post by wujj123456 »

When using Ubuntu, kernel updates appear regularly in Update Manager. I recently found that Mint Update Manager didn't display the recent kernel update (3.0.0-15). Are devs still testing it in Mint? Will it show up in the Update Manager at some point? Thanks.

For the update to show(provided it's there(which i think it should be)) you'll need to enable level 4 and 5 updates.To do this open up the update manager and choose edit>preferences.

Update any kernel showing in update manager reboot then if you want to update to 3.0.0-15 open a terminal and enter

Code: Select all

sudo apt-get update
then

Code: Select all

sudo apt-get dist-upgrade
once done reboot

this will update you to 3.0.0-15

Thanks. That's very helpful. I am a little confused, since Lv5 is tested, but Lv4 is not?

Thanks. I know this command, and that's how I found there is a kernel update. :P I am concerned about the stability since I had some problem with new kernels in Ubuntu 11.04. Updates worked fine for years until three month ago, a kernel update in my Ubuntu 11.04 led to some kernel module failure that I didn't know how to fix. (Thus I took the chance to switch to Mint, which works very well. )

Generally I'd advice only to upgrade your kernel if this will actually solve a problem you are having. Otherwise, it may just introduce new issues or sudden hardware incompatibility. But I may be a bit on the conservative side with regards to kernels; "don't try to fix it if it ain't broken." In all likelihood it will go fine, but just check that you know how to choose a different kernel to boot if you do run into issues.

Also, the dist-upgrade will install all updates. I'd generally advice you to use the Update Manager instead, and as hinted above make the level 4 and 5 updates visible. There may also be graphics card driver updates you don't want yet...

Thank you for the advice. I always update my kernel because I have my ssh server setup, and getting kernel security patches seems to be a good idea...

Another option is that instead of updating/replacing a Kernel, just add a newer one. This will allow you choose at boot up time to try the newer one or revert to the older one, should problems arise. See: http://forums.linuxmint.com/viewtopic.p ... 85&start=0
