Low disk space on file system message on:
- Elementary:
elementary OS Freya (64-bit)Built on "Ubuntu 14.04 LTS" - File manager:
Files 0.2.4
I want to create more disk space and running the command df-h gives the following output:
Filesystem Size Used Avail Use% Mounted on
udev 1.9G 4.0K 1.9G 1% /dev
tmpfs 390M 1.2M 389M 1% /run
/dev/sda1 19G 18G 637M 97% /
none 4.0K 0 4.0K 0% /sys/fs/cgroup
none 5.0M 0 5.0M 0% /run/lock

none 100M 44K 100M 1% /run/user
/dev/sdb1 823G 31G 751G 4% /home
I can't install any programs as there is no space on /dev/sda1, so I cannot install a program with a user interface to view files.
Therefore we took the following route:
So, the first disk is very small, and Plan A is just to free up enough stuff on it to stop it moaning. Plan B would he to move some stuff over to the spacious disk, and link it in. But hopefully A will work!
I reckon there's a lot of unused kernel images in /boot, it seeks to get a known weakness with elementary that it doesn't tidy old ones up. I had a web page up that described how to remove them and then update the grub menu so it didn't offer them anymore. But the first command was giving a funny error. I'm following the suggestions on this page:
How to remove old kernel versions?
So, we ran this command:
dpkg -l | fgrep linux-image-
It will list a lot of kernel images, most of which you aren't actively using. They're all similarly named, differentiated by a numerical suffix e.g. ".151" To find out which one you are using when you boot up, run this:
uname -r
The result was an old kernel image: 3.13.0-44-generic
We are assuming that any other kernel images newer than this can go:
So starting with 3.13.0-45-generic
$ sudo su
# apt-get purge linux-image-3.13.0-45-generic
# exit
Running this command produced the following:

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet de pendencies:

E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

I ran apt-get -f install but not sure if I should now run apt-get autoremove - I guess there will be a net gain of disk space that will accommodate the 13.5MB need for the new installations?
