[SOLVED] Install newer kernels manually?

Post by chris67 »

Hello

I have LM19.3 running 5.3 kernel but notice the 5.4 is available in Update Manager. Another computer has LM19.1 running 4.15 kernel which seems very old.

Should I install the 5.4 kernel on both? Just curious as to why update mgr wouldn't move to the newest kernel always.

Chris

Hi,

I did the same, no issues so far. You can go ahead with 5.4. However, you should leave at least one older kernel in the system as a fallback.

I guess this is because kernel updates are a sensible issue; that might potentially break things. Beforehand, there were update levels from 1 to 5 inside Mint Update Manager, 1 being the safest to update, while 5 being riskiest. I remember big kernel updates (such as 5.3 to 5.4) were treated as lv. 4 or 5.

Hello, Chris67.

The kernel series 4.15.0 is an LTS kernel series, long term support, i.e. supported till April 2023.
Provided a system runs perfectly on kernel series 4.15.0, there is no really good reason to change to a different kernel series.
In particular if the machine is an older machine with older hardware.

Reccent machines with recent hardware, however, may even force you to switch to a newer kernel series.
(Like my office machine e.g., where the hardware requires kernel series 5.0.0 or higher)

Update Manager will suggest switching to a newer kernel series to you, in case it realizes that the kernel series, which you are using, has reached the end of its supported life.
Kernel series 5.3.0 will reach the end of its supported life in August. Update Manager will suggest switching to kernel series 5.4.0 then.

Kernel series 5.4.0 is the next Ubuntu LTS kernel series, i.e. it will be supported till April 2025.

It is up to you to decide whether you wish to upgrade both machines to kernel series 5.4.0 or to stick with the current kernel series.

Best regards,
Karl

Kernel upgrades aren't like Windows updates.
"Latest Bleeding Edge" is a Windows mindset that has crept into the Linux world over the years. I wish that wasn't the case.
