You might see the following message (Continue without installing GRUB?). I recommend to check the checkbox and click on Forward so that the system will continue to use the old, working GRUB. If you don't check the checkbox , the update manager will install a new GRUB and ask you on which device/partition it should be installed which can make the system unbootable if you select the wrong device/partition.

Because we had to change the Release upgrade settings in the Software Sources window,
you will see the following message. It is ok to select Keep:
