Remove old kernel batch ..

It appears to be unmaintained/depreciated since Nov 2023. Also looking at the issues section tells a similar story.
As you are probably aware, you should not use any scripts blindly from the internet - if you have not reviewed their code properly & fully understand what they attempt to do.
Having said that, I have reviewed this one & use it frequently. Here is the actual code.
I simply use
apt autoremove --purge and it also removes old kernels (since PVE 7 or 6?).

That will remove & purge ALL packages automatically installed and not anymore required by any other package, (including system wide configuration files). Not just kernels exclusively. Also AFAIK if you manually added/installed a kernel - this command will not remove it.
Also this command does not give the user control over which kernels will actually be removed - and AFAIK will leave the current kernel + one before.
Also this command will not update the Grub config to reflect the remaining kernels available. You would have to subsequently add the
update-grub command to do that.Script above takes care of all the above.
Good point. I run it indeed to remove old packages that are no longer used, kernel or otherwise.
As you mentioned: kernels I installed explicitly are kept and others are removed. Usually what I want but maybe not what the OP wanted, I see now.
Actually, it does update my ESPs with systemd-boot (ZFS in UEFI mode without SecureBoot) using proxmox-boot-tool and I do not have to update anything manually afterwards.
Thank you for pointing out how my approach is not specific to kernels. I did not think about that as it works for the purpose of clean up in my case.
When you run
So you should probably run
update-grub it will run but you will get this warningGenerating grub configuration file ...W: This system is booted via proxmox-boot-tool:W: Executing 'update-grub' directly does not update the correct configs!W: Running: 'proxmox-boot-tool refreshSo you should probably run
proxmox-boot-tool refresh instead of update-grub
