Day 81: Upgrading Kali Linux

Kali Linux

upgrading kali linux

This is an OS centered around security.

And weirdly enough, there are not too much information on doing stuff on it.

It’s important to know that Kali is Debian-based.

Since it is debian-based, all/most debian commands and packages should work on it.

Check current version

uname -a


Linux 5.9.0-kali1-amd64 #1 SMP Debian 5.9.1-1kali2 (2020-10-29) x86_64 GNU/Linux

Upgrade packages

sudo apt-get upgrade

Not enough space in /var/cache/apt/archives/

In case you get this error like me, you do not need to repartition.

A simple fix would be creating a symbolic link to your larger partition.

  • Create a new directory on your larger partition, in my case /home/
df -h
#/dev/mapper/ichmachine--vg-var   2.3G  1.1G  1.1G  50% /var
#/dev/sda1                        511M  140K  511M   1% /boot/efi
#/dev/mapper/ichmachine--vg-tmp   1.8G  5.8M  1.7G   1% /tmp
#/dev/mapper/ichmachine--vg-home   93G   16G   73G  18% /home

sudo mkdir -p /home/apt-cache
  • Copy oroginal cache dir to the new dir
    cp -rp /var/cache/apt /home/apt-cache/
  • Remove the original directory if everything was copied successfully
    rm -rf /var/cache/apt
  • Create new symbolic lin to the new directory
    ln -s /home/apt-cache/apt /var/cache/apt
  • Retry the upgrade again. It will work now.

  • After the upgrade is done, you can do a
    sudo apt-get clean

Upgrade kali to latest

sudo apt dist-upgrade

Clean up unneeded packages

sudo apt autoremove

Check new version

uname -a


Linux 5.10.0-kali4-amd64 #1 SMP Debian 5.10.19-1kali1 (2021-03-03) x86_64 GNU/Linux

Rolling back changes to cache

Only if you got the same space issue as me

sudo rm -i /var/cache/apt

sudo cp -rp /home/apt-cache/apt /var/cache

rm -rf /home/apt-cache
