Update to a lower version

Asked by gpt

Hi,

I use kernel 5.15.0-124 due to a problem in hotspot operation. On Monday (15/Sep/2025) an update appeared with semantic 5.15.0-25!

Is that correct? Should I proceed to update the kernel?

I'd say yes. Updates are useful. You can always boot an older kernel using GRUB if you have issues

Thanks for your quick response "andrew-woodhead666".

I understand and totally agree with you that updates are useful.

What I do not really understand is how a kernel with lower semantics "5.15.0-25" can be an upgrade of a kernel with higher semantics "5.15.0-124". Do I miss something? I am not an IT folk.

PS: In addition, Kernel "5.15.0-25" is marked as "Superseded" after installation!

In Ubuntu terms the version number 5.15.0-25 is lower than 5.15.0-124 and Ubuntu will never offer an "upgrade" from 5.15.0-124 to 5.15.0-25, because that is a downgrade and the package management system will perform a downgrade only when specifically instructed to do so.

For diagnostic purposes please provide the output that you receive for the following commands (to be executed in a terminal window)

uname -a
lsb_release -crid
dpkg -l | grep ' linux-i'
apt list --upgradable

Thanks for your quick response "Manfred Hampl (m-hampl)",

Your response is clear. The mistake apparently belongs to some other group, out of Ubuntu Community. i do not want you spend more time on that.

Many thanks.
