Xanmod kernel and needrestart

[og900aero]

Hello. I use Xanmod kernel with Debian 12 stable. When I upgrade Xanmod kernel, then needrestart package show message:

I rebooted server and fastfetch show uses new kernel, but needrestart show again this message. What should I do?

[phd]

I've had the same issue with needrestart and xanmod kernels on Ubuntu for a long time now, on all versions of Ubuntu: 24.04, 23.10, ...

$ needrestart -k
Scanning linux images...                                                                                            

Pending kernel upgrade!

Running kernel version:
  6.8.10-x64v3-xanmod1

Diagnostics:
  The currently running kernel has an ABI compatible upgrade pending.

Restarting the system to load the new kernel will not be handled automatically, so you should consider rebooting.
[Return]

No amount of restarts gets rid of this false-positive result.

This might be related to #263. Could you apply d3e33025 locally (or switch to git HEAD) to check if the issue is already resolved?

I installed needrestart from Debian 12 repo (apt install needrestart). Can I get apply patch to this, or I must use git version?

Try the following patch:

To apply this patch run this command patch /usr/lib/needrestart/vmlinuz-get-version as root and paste the patch to stdin. This change will be overriden next time you upgrade or reinstall needrestart.

patch /usr/lib/needrestart/vmlinuz-get-version

I applied this patch, but when I run sudo needrestart, I get message (like first post) again. Maybe need reboot, and try again?

[liske]

A reboot ist not required, can you please provide the output of needrestart -v -k ?

Thanks for checking.

Sadly the above patch was incomplete. I've tested needrestart's git HEAD on a test vm with xanmod kernel and the issue did disappear.

needrestart's git HEAD on a test vm with xanmod kernel and the issue did disappear.

How can I run needrestart from git? # ./needrestart doesn't seem to work. Do I have to make install?
