Ubuntu installation appears "error deleting Initramfs-tools", subprocess installed post-installation script returned error exit status 1

Yesterday ready to reload Ubuntu, increase the system capacity, because the front to use the boot partition less than 100M, so here the partition is as follows

/boot	100M
/	30G
/home	50G

Then the installation ends as soon as the problem occurs

began to think that the mirror did have a problem, and then re-created the image, installed two times, failed

Search online again, search subprocess installed ..... Can not find any valid content, search "Delete initramfs-tools error" found a few netizens encountered the same problem, but did not give a solution, finally in Baidu Bar http://tieba.baidu.com/p/4307483400, Netizen Littlekubby mentioned may/boot partition is too small, so hold a try mentality, re-divided the district

/boot	200M
/	60 "
/home	50G

,,, bingo, the installation was successful!

Here you can be sure that the problem I installed is that the/boot partition is too small, and here is just one possible way to write it down.
