I have Ubuntu running on a virtualbox VM. When I start Ubuntu, it reports "Low Disk Space". But when I check my partitions, I don't see where. I have a 2GB Swap partition and / is a 14GB partition with 2.5GB free space. When I run an update, it is as:

sudo apt-get update && sudo apt-get -y upgrade && sudo apt-get clean && sudo apt-get autoremove

I've also tried using bleachbit, but I still get the error. enter image description here

  • The recommended minimum disk allocation has been 25GB since Ubuntu 17.10 (or all releases using GNOME Shell) https://help.ubuntu.com/community/Installation/SystemRequirements, so you need to watch your usage given you've chosen to use less space. I'd suggest using du (disk usage) to narrow down & consider increasing size of your partition to recommended minimum. (yes many users & bloggers get by on less; but they nuke & install rather than release-upgrade, don't add many packages etc..) – guiverc Jul 13 '21 at 06:40
  • The notification is "low disk space" but the details say 0 bytes remaining. Once your root file system runs completely out of space it can become easily corrupted. The closet analogy is suffocation. You may need to reinstall the OS. Consider a dynamic container size with a large enough maximum size so that this doesn't happen again. – Nmath Jul 13 '21 at 06:40

    Does this answer your question? Root drive is running out of disk space. How can I free up space? – Artur Meinild Jul 13 '21 at 07:37

probably your /boot has too many kernel versions

first get all kernel list:

dpkg --get-selections | grep "linux-image-[[:digit:]].*" | tr "\t" ";" | cut -d ";" -f1

the result would be sth like:

linux-image-5.3.0-28-generic
linux-image-5.4.0-62-generic
linux-image-5.4.0-65-generic
linux-image-5.4.0-66-generic

then delete just old kernels:

sudo apt-get purge linux-image-5.3.0-28-generic

and delete unused packages:

sudo apt-get autoclean && sudo apt-get autoremove
