Not enough free disk space 

The upgrade has aborted. The upgrade needs a total of 101 M free 
space on disk '/boot'. Please free at least an additional 101 M of 
disk space on '/boot'. You can remove old kernels using 'sudo apt 
autoremove' and you could also set COMPRESS=xz in 
/etc/initramfs-tools/initramfs.conf to reduce the size of your 
initramfs.
