Recently I made a fresh install of Ubuntu 15.10 on my laptop after erasing everything. I have got notification from update manager to update my system. But I am getting the below error which says the size of '/boot' partition needs to be increased.
The upgrade needs a total of 90.1 M free space on disk '/boot'. Please free at least an additional 2,999 k of disk space on '/boot'. Empty your trash and remove temporary packages of former installations using 'sudo apt-get clean'.
Is it a method that I reduce '/home' with say 300 MB and mount this new partition on a directory under '/boot'? Will it work? No I don't think so because while installing at the time of updating via software updater, the system can install anywhere and at many places under /boot. Isn't it? So, it shouldn't work. Also, I wouldn't prefer mounting on '/boot' any partition from extended partition. As my '/boot' is on primary parition, I would prefer it to be completely on primary partition.
Now the only way striking my mind is to shrink the adjacent partition i.e. '/' (root partition) from the start point of the partition and add it in '/boot'. For that I have to boot using live usb drive. So, as my system has separate '/boot' and '/' partitions, so I think shrinking the root partition from the start point may not create any problem while rebooting! What you say please?
