to many items in /boot

[BoneSaw]

so recently in an attempt to upgrade to 8.10, i have come to realize that my /boot partition has about 6 different kernels wasting space.

according to uname -r, i am using 2.6.24-21 generic. is it safe to delete the rest of these? (i have found no problems with this kernel yet.

if so which files should i delete?

here is an ls readout of /boot

Yes it is safe to remove the older kernels. I'd recommend keeping at least one older kernel which you know worked well in the past.

You can use the package manager (Synaptic for example, in System - Administration - Synaptic) to uninstall them. Look for the linux-image and linux-headers packages and uninstall the previous versions.

thanks a bunch to both of you.
