[xubuntu-users] "Not enough space on disk /boot"

[Thomas Blasejewicz]

Good evening
In more or less regular intervalls, when the computer tries to "update", 
I get the following error message:

"Not enough free space.
The upgrade needs a total of 81.9 MB of free space on the disk /boot.
Please free at least an additional of 20.4 MB of space on the disk /boot.
Empty your trash and remove temporary packages of former installation using
sudo apt-get clean."

File manager shows:
/boot = total space = 248.8 MB
used space  169.5 MB = 75%

I did not set this myself. However, I do recall using "entire disk + 
LVM" during setup and read somewhere, this might be problem.

What is this all about, and is there a way to make all this "automatic"?

Thank you.
Thomas
