[Bug 1521169] [NEW] The link /vmlinuz is a damaged link

[David Henningsson]

Public bug reported:

Steps to reproduce:

1) Install daily build of Ubuntu 16.04.
2) Install another kernel, in my case this one: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4-rc3-wily/linux-image-4.4.0-040400rc3-generic_4.4.0-040400rc3.201511300321_amd64.deb
3) Immediately remove the new kernel after adding it.
You will now receive the following scary message:

The link /vmlinuz is a damaged link
Removing symbolic link vmlinuz
 you may need to re-run your boot loader[grub]
The link /initrd.img is a damaged link
Removing symbolic link initrd.img
 you may need to re-run your boot loader[grub]

...although it seems relatively harmless. I think the key to reproducing
it is that you have to go from 2 to 1 kernels (it won't reproduce if you
have 3 kernels installed and remove one of them).

Somewhat related to bug 924742, but I have not installed any home
compiled kernels, only one from the kernel mainline ppa.
