  • Welcome to AskUbuntu! Which release of Ubuntu you use ? – pasman pasmański Nov 27 '21 at 07:51
  • Ubuntu `20.04 LTS` – Avijit Nov 27 '21 at 08:08
  • You can delete stuff in your /home/youruser/ folder but not the hidden folders within it. You can uninstall apps and snaps. You can search for tutorials about how to free up space such as this one https://itsfoss.com/free-up-space-ubuntu-linux/ – PonJar Nov 27 '21 at 08:18
  • The largest directories you have are ´7var` and `/home` at 12G and 16G.Look into thes and see what large file and directories there are. In /var it is typical /var/log. Find out what logs that grows and the errors that makes them grow- Fix the errors and delete the old versions of the log-files - typically there are 3 to 5 versions of each logfile. – Soren A Nov 27 '21 at 08:27

  • Does this answer your question? [Very large log files, what should I do?](https://askubuntu.com/questions/515146/very-large-log-files-what-should-i-do) – karel Nov 27 '21 at 12:22
  • @karel No, it's a different question. – Avijit Nov 27 '21 at 12:52
  • I'm going to leave it anyway because `/var` is maybe where the unneeded large files are located. – karel Nov 27 '21 at 12:55
  • Ok thank you @karel – Avijit Nov 28 '21 at 06:40

There's a number of things you can do:

  • Install BleachBit: deletes unnecessary files.
  • Remove old revisions of snaps.
  • Check further options in Ask Ubuntu.

Here's the code that you need to put in a shell script and run (2nd option):

#!/bin/bash
# Removes old revisions of snaps
# close all snaps before running this!!
     
set -eu
LANG=C snap list --all | awk '/disabled/{print $1, $3}' |
while read snapname revision; do
    snap remove "$snapname" --revision="$revision"
done

Maybe this will help some people. I just ran $ docker system prune -a on my work laptop and personal laptop and it cleared, respectively, 75 Gb and 50 Gb of disk space. Lots of Docker stuff hanging around apparently even though if I ran $ docker ps -a there was nothing there.
