boot partition full

[luca moscato]

Env: Ubuntu Desktop 16.04 LTS 64bits

Hi all
at the beginning of september 2017 I set up a new pc for a desktop user, command line never used. Now after 5 months of daily use I received the alert about /boot partition almost full, see below

[ALL AUTOREMOVE STUFF...]

And after

user@latitude5580:/boot$ df -h
File system Dim. Usati Dispon. Uso% Montato su
/dev/sda2 473M 142M 307M 32% /boot

Basically, it seems that with default settings and if the user doesn't perform an autoremove from command line there is the chance to fill the /boot partition. This should be avoided since not every user is familiar with command line

Could the issue be related to a config by unattended upgrades

--
Whether or not unattended-upgrades will perform the cleanup (auto remove) is controlled by the Unattended-Upgrade::Remove-Unused-Dependencies setting in /etc/apt/apt.conf.d/50unattended-upgrades. Set it as follows to enable the cleanup -- and you should be able to remove the explicit autoremove cron-job:

Unattended-Upgrade::Remove-Unused-Dependencies "true";
