Re: Remove old kernels, how?

sudo apt search linux-image-* | grep installed

This is mine.

linux-headers-6.12.101+deb13-amd64/stable-security,now 6.12.101-1 amd64 [installed,auto-removable]
linux-headers-6.12.105+deb13-amd64/stable-security,now 6.12.105-1 amd64 [installed,automatic]
linux-headers-6.12.107+deb13-amd64/stable-security,now 6.12.107-1 amd64 [installed,automatic]
linux-headers-6.12.74+deb13+1-amd64/now 6.12.74-2 amd64 [installed,local]
linux-image-6.12.101+deb13-amd64/stable-security,now 6.12.101-1 amd64 [installed,auto-removable]
linux-image-6.12.105+deb13-amd64/stable-security,now 6.12.105-1 amd64 [installed,automatic]
linux-image-6.12.107+deb13-amd64/stable-security,now 6.12.107-1 amd64 [installed,automatic]
linux-image-6.12.48+deb13-amd64/now 6.12.48-1 amd64 [installed,local]
linux-image-6.12.74+deb13+1-amd64/now 6.12.74-2 amd64 [installed,local]
linux-image-amd64/stable-security,now 6.12.107-1 amd64 [installed]

I then just step through the list one by one using sudo apt remove to just leave 2 kernels followed by sudo apt autoremove to clear any kbuild and header files

sudo apt remove linux-image-6.12.101+deb13-amd64
The following packages were automatically installed and are no longer required:
  linux-headers-6.12.101+deb13-common   linux-kbuild-6.12.101+deb13
  linux-headers-6.12.74+deb13+1-common  linux-kbuild-6.12.74+deb13+1
Use 'sudo apt autoremove' to remove them.

REMOVING:
  linux-headers-6.12.101+deb13-amd64  linux-image-6.12.101+deb13-amd64

If you have Synaptic installed you can just use that and pick all the ones you want to remove in one go.

Re: Remove old kernels, how?

Thanks a lot
For me working solution is Synaptic.
