I just tried to do a
sudo do_release_upgrade on an AWS EC2 Ubuntu 13.10 server to upgrade to 14.04. All was going well until I got the following message:
A new version of /boot/grub/menu.lst is available, but the version installed currently has been locally modified. What would you like to do about menu.lst? * install the package maintainer's version * keep the local version currently installed * show the differences between the versions * show a side-by-side difference between the versions * show a 3-way difference between available versions * do a 3-way merge between available versions (experimental) * start a new shell to examine the situation <Ok>
I certainly haven't modified menu.lst, so I assume the local modifications are Amazon's doing. I'm going to hit the "keep the local version currently installed" option and hope for the best.
But why am I getting this message, and is this the correct way to handle it?
