When trying to run the automatic update I get as alarm that " Your boot sector is full" try to delete you trash or/and run: sudo apt-get clean in your bootsector .
I've tried but it doesn`t help - bootsector is about 245MB large on Ubuntu 14.04 and 500 Gb HD
vmlinuz are found in a number of 6 - from 23 and upward to 30.
so due to an anserw it should be to delite nr 2323,24,25 and 26. there is som **.efi to.
So i stared whith nr 23.
terminal: sodu apt-get purge linuz-3.16.0-23-generic and enter o c.
result:command not found ???????? by all means i have seen som odd signs like a parashute in 90degress turn but that i have not seen on my keebord.
Obviusly i am doing somthing wrong - BUT WHAT??
