oldkernelsrm

[Grimble]

Directed to Dave Hodgins:
Dave, I just used your script to remove old kernels. Normally there's no
additional output but this time for each of 4 kernels there was this:

removing package kernel-desktop-5.15.4-1.mga8-1-1.mga8.x86_64
2/4: removing kernel-desktop-5.15.4-1.mga8-1-1.mga8.x86_64

###################################################################################################
Usage: grub2-set-default [OPTION] MENU_ENTRY
Set the default boot menu entry for GRUB.
This requires setting GRUB_DEFAULT=saved in /etc/default/grub.

-h, --help print this message and exit
-V, --version print the version information and exit
--boot-directory=DIR expect GRUB images under the directory DIR/grub2
instead of the /boot/grub2 directory

MENU_ENTRY is a number, a menu item title or a menu item identifier.

Report bugs to <bug-***@gnu.org>.

A bit strange.....

That's coming from update-grub when it's automatically run after removing a
kernel using rpm or urpme commands, which the oldkernelrm script generates.

What's the contents of /etc/default/grub?

/etc/default/grub:
GRUB_CMDLINE_LINUX_DEFAULT="splash quiet noiswmd
resume=UUID=ca3503c1-ae8b-40a0-b1a8-30743e411bea audit=0 vga=791"
GRUB_DEFAULT=saved
GRUB_DISABLE_OS_PROBER=false
GRUB_DISABLE_RECOVERY=false
GRUB_DISABLE_SUBMENU=n
GRUB_DISTRIBUTOR=Mageia
GRUB_ENABLE_CRYPTODISK=y
GRUB_GFXMODE=1024x768x32
GRUB_GFXPAYLOAD_LINUX=text
GRUB_SAVEDEFAULT=true
GRUB_TERMINAL_OUTPUT=gfxterm
GRUB_THEME=/boot/grub2/themes/maggy/theme.txt
GRUB_TIMEOUT=10

So it looks as though GRUB_DEFAULT is correct.

Yes. That looks fine. Mine has $ cat /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="noiswmd modprobedebug rd.luks=0 rd.lvm=0 rd.md=0 rd.dm=0 audit=0 rd.driver.pre=ehci_hcd net.ifnames=0 pcie_port_pm=off pcie_aspm=off 3 nosmt=force vga=788"

I've checked and the last time that error msg was included in a bug report was
around 18 months ago.
https://bugs.mageia.org/show_bug.cgi?id=27215#c13

That msg was overlooked at that time as it occurred during kernel installation
and the reboot into the new kernel worked ok. I've never seen it on one of my
kernel installs or removals.

I have no idea what's causing it. If you can recreate it, which will likely
require re-installing an older kernel, please open a bug report. The kernel/grub
experts will likely be able to figure it out.
