Ubuntu

Not enough free space for update

Asked by John Gustafson

Not enough free disk space
The upgrade needs a total of 78.4 M free space on disk '/boot'. Please free at least an additional 7,655 k of disk space on '/boot'. Empty your trash and remove temporary packages of former installations using "sudo apt-get clean".

I have recently installed 14.04 LTS

I do not have enough knowledge/experience to resolve this.

Previous posts seem to be version specific so I am reluctant to try those solutions.

The output of the commands proposed by me shows:

1. You have a /boot partition of 236 MB size
2. Before the dpkg --purge action you had four versions of the kernel image installed (each one consisting of two packages), totaling 156 MB, so each one is about 40 MB. This is in line with the status after removal with 119 MB used by three kernel versions.

The limited size of the /boot partition restricts the number of kernel versions that you can have installed at the same time. So you must make sure to remove an old obsolete kernel before update management tries to add another one.

On the Ubuntu release that you are running, the terminal command

sudo apt-get --purge autoremove

should automatically uninstall old obsolete kernels. You should execute that command periodically.

You can check the number of installed kernel packages with the command

dpkg -l | grep linux-image

or by checking

ls /boot

Can you help with this problem?
