Thank you for the reports.
@GG HH
Can we take it that this problem is new since the recent urpmi update you note?
Assuming this to be the case, assigning to tv who did that.

I have never before seen a kernel in a "urpme --auto-orphans" list; this must be special to more than 1 version of the same kernel.
As an aside, old kernel removal is now best done with our new 'remove-old-kernels' package.

Hi Lewis,

before this update, the running kernel was not removed by urpme --auto-orphans. 
It looks sensible as the last kernel could be failing to boot and this situation may be a bit tricky to cope with for an average user.

The use case is:
- upgrade the packages, a kernel upgrade is part of the update
- remove deprecated versions. with this update, the running kernel is remmoved.
- reboot
the only available kernel is the new one. It may not boot. if so no fallback is available.

More over, i assume that modules which would not be already loaded would not be available until reboot.

Reading marc answer : it looks like actually all installed kernel would be removed - urpme line is probably missing.
Strange. I do not have rebooted my self.

Regards

Testcase with 8 installed kernels

There is no risk that a kernel get removed. I did a intense testcase with an cauldron Virtualbox installation with 8 installed kernels. But the output of "urpme --auto-orphans" is misleading and may confuse new unexperienced users. 

Short testcase summary:
- update cauldron (latest kernel-desktop-6.2.11-1.mga9.x86_64 gets installed)
- NO restart of computer
- "uname -r" shows still 6.2.10-desktop-2.mga9 as active
- "rpm -q -a |grep kernel-desktop|sort" shows 8 installed kernels
- "urpme --auto-orphans" lists ALL kernels to remove (with many other pcks as it is a grown VB installation)
- let "urpme --auto-orphans" remove ALL packages including ALL kernels
- restart computer
- "uname -r" shows now 6.2.11-desktop-1.mga9 as active
- "rpm -q -a |grep kernel-desktop|sort" shows still all 8 kernels installed 
- "urpme --auto-orphans" does no longer list any kernels to remove

As "urpme --auto-orphans" is no longer capable of removing kernels due to the new naming, it only "deletes" or clears the orphans list but doesn't uninstall any kernel. Kernel removal in MGA 9 is now automatically done by the new remove-old-kernels tool.

As the output is a little bit longer i attached the complete terminal output of the upper testcase as proof that there is no risk of loosing a kernel.

I have a problematic behavior similar to the one described by Thierry.  I installed mageia 9 via a net installation.

The removal of kernel-desktop-devel is problematic as it is used for dkms for the proprietary driver nvidia....Unless headers are enough, but I haven't had this behavior historically since I've been using mageia.

To satisfy dependencies, the following package will be removed (87MB):

  kernel-desktop-6.2.10-1.mga9.x86_64
Remove 1 package? (y/N) n

imho _this_ is not just confusing for new unexperienced users.
It is plain wrong if it does not what it says it will.
