Root / partition full on Kali, is 18GB enough space? Which files are safe to delete from / partition?
by dizmizz from LinuxQuestions.org on (#51Q06)
Hi,
I have my hard drive partitioned with Kubuntu 18.04, Kali 5.4.19 and Windows 10.
After a bit more than half a year with this set up my root / partitions of my Kali keeps getting filled up.
I have followed guides to remove old images, sudo apt-get autoremove, sudo apt-get clean and to use du -h <dir> | grep '[0-9\.]\+G' and du -hx --max-depth=1 / | sort -h to track the biggest files.
It freed up 1%, so I started to look into programs I could sacrifice.
Sadly Android Studio had to go, and it freed up another 9%.
But, my questions then are if 18GB is enough space for the / partition?
If it is enough, then which files are safe to delete?
I have 100GB for my Kali /home partition, and 243GB for my Kubuntu since it is the main OS I am using.
And I have /boot as a part of the / partition for both of them. Both of them have 18GB for their separate / partitions.
But only Kali seems to run out of space all the time, not Kubuntu.
I have look for big files in /tmp and /var/log but no one is big, and I removed some of them anyway.
