I am doing an in-place upgrade from 12.04 to 14.04 and all is
going well, except...
I have a bunch of files in /boot, some abi-..., some config-...,
some initred.img-..., some some vmlinuz-..., and
some others.
The upgrader is doing something to those files and it is taking
roughly forever. I thought it was a loop until I noticed that
the kernel numbers were changing.

here is what it keeps repeating:
Updating /boot/grub/menu.lst ... done

Removing linux-image-3.2.0-32-generic (3.2.0-32.51) ...
Examining /etc/kernel/prerm.d.
run-parts: executing /etc/kernel/prerm.d/last-good-boot

Examining /etc/kernel/postrm.d .
run-parts: executing /etc/kernel/postrm.d/initramfs-tools
3.2.0-32-generic /boot/vmlinuz-3.2.0-32-generic

Searching for GRUB installation directory ... found: /boot/grub
Searching for default file ... found: /boot/grub/default
Testing for an existing GRUB menu.lst file ... found:
Searching for splash image ... none found, skipping ...

I presume that it is processing all the kernels it is finding.
I have 3 more machines to upgrade. Can I safely remove most of
the files in /boot?

Now, of course, if I am missing the boat, I would appreciate any
suggestions you might have.

file ranges:
abi-3.2.0-51-generic (and generic-pae)
through abi- (and generic-pae)

config- through
config- (and generic-pae)

initrd.img-2.6.28-server through
initrd.img-3.2.0-69-generic ( and generic-pae)

3 memtests through (and generic-pae)

3 vmcoreinfo files

vmlinuz-2.6.28-18-server through
vmlinuz-3.2.0-69-generic (and generic-pae)

Yeah, I know a fresh install would have been better, but the lure
of quick and simple...

Purge all your old kernels except the latest one before you upgrade.

What you see are all the older kernels and their helper files that were
once installed on the system.
These are not automatically removed after an upgrade, because something
might go wrong and you may want to revert to an older kernel.

You can safely remove all older kernels if the one you are using now is
known to be good.
But you should do this *before* attempting the upgrade to 14.04, not
during ;-)

See for example
<a href="" title=""></a>

That scary " sudo apt-get remove --purge ..." command basically just
checks which kernel you are using now, and then removes all other
versions. You can also do that manually if you feel more confident that
dpkg -l 'linux-*' shows all the installed kernels
uname -r shows the kernel you are currently using
sudo apt-get remove --purge linux-.... will remove a certain
kernel. Repeat this for all old kernels that you do not want to keep.

I used the "scary" script on that page and it ran fine. When it
got done only the current kernel was in the /boot directory.
dpkg -l 'linux-*' still shows many, many linux-image-* files.
How do I tell dpkg that they are gone ?

Thanks Patrick. That helps. And I WILL do it before starting
the next upgrade.
