Hi,
with every kernel-update dietpi/debian keeps the old kernel. How can I remove the old kernels?

can you try following
```auto
apt autoremove
```
Usually this should remove not needed packages
There should be a similar message while running `apt upgrade`
```auto
root@DietPi:~# apt upgrade

The following package was automatically installed and is no longer required:
linux-image-6.1.0-18-amd64
Use 'apt autoremove' to remove it.
The following NEW packages will be installed:
linux-image-6.1.0-20-amd64
```

Autoremove does not remove the unused kernerl’s. This is part of my Alias in bash to run an update/upgrade.

Testing on a VM is working quite well

Did you tried running `apt autoremove` after a reboot?
And what is the output of following
```auto
dpkg -l linux-image*
```

A reboot give the same result for auto remove.
```auto

looks like all the kernel packages are still installed. Therefore `apt autoremove` did not have any effect.
Can you try to remove one of the packages manually? Like
```auto
apt purge linux-image-5.10.0-19-amd64
```

That worked. So I have to do that with the other kernel’s too.

yes this time. Usually it should happen automatically. At least it is removing old kernel on my demo VM.

When upgrading the kernel, a window always opens and you are asked whether you want to delete the currently active kernel. Can this be done safely?
