Aptitude full-upgrade upgraded kernel to 3.13.0-68. Kernel has been installed but grub.cfg is not updated properly, neither from post-install nor from a manually initiated update-grub. Tried reinstalling all of grub + kernel. Still doesn't work. Installing the kernel produces the following:

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1516014

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

I can run apport-collect, but it won't go through the proxy (I already tried http_proxy and https_proxy). Is there a way of doing this offline and then sending the report manually?

[Mark Dunn (mark-dunn75)]

Checked with "grub-probe -v" today and got:

grub-probe: info: /dev/sda is a parent of /dev/sda.
grub-probe: info: opening hd0.
grub-probe: info: drive = 0.
grub-probe: info: the size of hd0 is 125045424.
grub-probe: error: unknown filesystem.

Changed type from ext4 to ext2 and grub-update works again. Looks like ext4-support for /boot has been stripped from grub-update (at least for trusty with 32 bit, my trusty machine with 64 bit does not have this problem, both have version 2.02~beta2-9ubuntu1.4)
