I installed Kali Linux on VM VirtualBox(my host is Ubuntu 18.04). I am newbee to Kali,but the two linked questions are not related to my problem. When I try to upgrade Kali

apt upgrade

926 upgraded, 81 newly installed, 0 to remove and 4 not upgraded.
Need to get 1,503 MB of archives.
After this operation, 622 MB of additional disk space will be used.

How should I change my filesystem configuration? udev is not used at all,why?

  • You're running LVM for your root filesystem so you may be able to extend it. Have you checked if there's any space in your PV? (pvs and then maybe lvextend).

  • Since it's Kali and you won't be using it as a primary OS you may be able to delete whatever has filled up your root partition. That would get you back several GB.

  • @roaima How to delete tmpfs?

    This is, IMHO, not a duplicate of the "Why is Kali so hard" question. It's a fairly obvious case of not having allocated enough space for a disk in VirtualBox.

    There's no point deleting a tmpfs as it's memory-based. You need either to review the stuff you've created but not deleted or to increase the sieve available in Vbox for your root PV, and thence your root LV. It really would be worth drilling down into /usr to see what's eating all the disk space.

As you surmised, the issue is simply that you don't have enough space in your VirtualBox instance.

This line says it all:

/dev/mapper/kali--vg-root   12G   11G  250M  98% /

So you only have 250 MB of vacant space. And as apt is helpfully telling you:

After this operation, 622 MB of additional disk space will be used.

The solution is simple. Just extend the Logical Volume (LV) that your Virtualbox instance is living on. lvextend should do it. man lvextend should give you sufficient information. Ask on the site or in chat if you need more help.

  • pvs shows there is nothing free and available to extend within the existing space

  • @roaima Yes, we covered that in chat. He's not allocated space to the VB instance properly. He has plenty of space available in the host, though he isn't using LVM there.

Backup the virual machine ( clone it) then resize the virtual hard drive:

To incrase the kali.vdi from ~10 G to ~20 G use the following command (from Ubuntu):

VBoxManage modifyhd /Path/to/kali.vdi --resize 20000

Then download Gparted or use a linux live USB.

From Virtualbox, navigate to Setting > Storage > Controller IDE , then attach the gparted.iso

Configure the Virtual-Machine to boot from the optical drive (under Settings > System > Motherboard)

The virtual machine will boot into Gparted, you will be able to resize the virtual hard drive (10 ~> 20 G), apply changes , exit (shutdown)

Remove the attached gpartd.iso from the Controller IDE, then boot your virtual machine.

    Why do you suggest all the juggling with a live iso? IMHO all that's needed is to run fdisk /dev/sda (or any other partitioning tool) from Kali, enlarge sda5 (delete & recreate with the same start sector), reboot and pvextend. Or if OP is not brave enough to play with sda5, create a new partition, pvcreate and vgextend.

  • It's a virtual machine with root on an LV. Extend the allocated disk. Extend the PV. Extend the LV. At most only the first operation requires the VM to be shut down, and possibly not even that.
