My computer keeps asking me to update but there is no space, boot memory at 100%. Have tried apt-get clean, sudo apt-get clean and sudo rm .xsessions-errors.

None of which work. Any suggestions greatfully received. NB, I am NOT a computer whiz so baby steps PLEASE

sudo apt-get autoremove

This command removes the unnecessary packages

sudo apt-get autoclean

This is same as a clean command

you can also use Ubuntu tweak program and clean using janitor option

    Those commands apply to apt cache located in /var/apt/cache. Nothing to do with /boot – Cornelius Apr 24 '14 at 10:30

boot partition contains boot loader files, kernels, modules, init ram disks and some additional components. Probably you have few versions of kernels + adds and it consumes you space within /boot partition. For example:

root@server# ls -1 /boot

Check which version of the kernel(s) you are really using now and remove unnecessary ones.

BE CAREFUL! ;-)
