I am working on an Ubuntu virtualbox and trying to install curl using sudo apt-get install curl -y.

I got a response saying there were unmet dependencies and saying You might want to run 'apt-get -f install' to correct these:

So, I execute apt-get -f install and encounter a new problem:

After this operation, 43.0 MB of additional disk space will be used.

Basically, it's complaining there is no space left on device. df -h confirms:

Filesystem                Size  Used Avail Use% Mounted on
/dev/mapper/ITS--vg-root   38G   18G   18G  51% /
none                       4.0K     0  4.0K   0% /sys/fs/cgroup

/dev/sda1                  236M  226M     0 100% /boot

So if I'm reading this correctly, apt-get -f install is trying to write 43.0 MB worth of content into available space of 18G.

Why is it complaining there is inadequate space?

Your problem isn't the 18GB free on /

The problem is:

/dev/sda1                  236M  226M     0 100% /boot

The package installer is working on /boot/vmlinuz-3.13.0-91-generic and there is no space available.

You need to increase the size of this partition.

As Anwar stated in comment a minute ago see: askubuntu.how-do-i-increase-the-size-of-boot

Originally I said to see the Q&A: askubuntu.com ..how-to-increase-size-of-boot-partition-using-gparted which is also helpful.

  • @Anwar if that was his question yes. I'm a little unclear because the cause of the problem needed to be explained, ie 18GB free wasn't the issue. Sep 14, 2016 at 10:30
