Comment 12 for bug 202009

Can confirm this. The same issue: aptitude installed the newer kernels, I failed to allow the postinstall script to overwrite grub.lst. I thought it wants to change some default values, that I set to my preferences, and the boot lines are going to be updated anyway, later, when update-grub is called by postinstall.

But update-grub does not rewrite the appropriate lines, even as it prints out correct "Found kernel: " lines. It does not updates them even when called later manually.
