Understanding Old Kernel for Removal

[Nollimox]

So, I did this:
Linux nolliprivatecloud 6.5.11-7-pve #1 SMP PREEMPT_DYNAMIC PMX 6.5.11-7 (2023-12-05T09:44Z) x86_64

root@nolliprivatecloud:~# dpkg -l | grep pve-kernel
ii pve-firmware 3.9-1 all Binary firmware code for the pve-kernel
ii pve-kernel-6.2 8.0.5 all Proxmox Kernel Image for 6.2 series (transitional package)
ii pve-kernel-6.2.16-3-pve 6.2.16-3 amd64 Proxmox Kernel Image
root@nolliprivatecloud:~#

And


So, why 6.5.11-7 didn't show up when I ran (dpkg -l | grep pve-kernel)? How do I remove both kernel 6.5.11-4 and 6.2.16-20...I take it that the "white space" is kernel 6.5.11-7...
This command also doesn't show that 6.5.11-7 is installed...

root@nolliprivatecloud:~# apt list --installed | grep pve-kernel

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

pve-kernel-6.2.16-3-pve/stable,now 6.2.16-3 amd64 [installed]
pve-kernel-6.2/stable,now 8.0.5 all [installed]
root@nolliprivatecloud:~#

So, why 6.5.11-7 didn't show up when I ran (dpkg -l | grep pve-kernel)?

Because it was renamed to: proxmox-kernel at some point not far back.

Okay, thanks Neobin for explaining. So, how would I remove both the old pve-keneral and proxmox-kernel with one command?

apt autoremove takes care of old kernels, based on the following criteria:

If you want to remove more, you need to do it manually.
