Probably best results as root.

Thanks...
What i was doing is i added too much iso's on /var/lib/libvirt/images
I guess i had to add more gb on / though...

I used to have a /boot partition, but with UEFI it was difficult to manage the size (it only filled up once but that was enough),

so I stopped worrying about /boot file space. (The bios partition only requires 100Mb)

your / is 28Gb... I reserve 28Gb just for /var. here's the rest...

Some places you can check for swelling...
/tmp/
/var/log/
/var/cache/apt/archives/

just my two cents worth. :-)

Your Downloads folder is huge and the key reason why your / has filled up. I take it you downloaded a lot so clearing that one out will release a decent amount of storage.

well in most cases seperate partition for /var /usr and /tmp won't be a thing to consider
but i have a seperate /home partition which is around 440 gb and i am using only 6% of it
why my / is full i don't get it and i think i know what i am doing...
generally / is where things like programmes are stored while /home is where personall folders are stored
you are saying i have to create a bigger / partition rather than /home partition ? I don't get it but i would like to see what you are talking about...
thanks!

Hello i use devuan daedalus. My partition scheme has 4 partitions 1. for bootloader, 1 for swap, 1 for root and 1 for /home.
My ssd is almost 500gb (patriot ssd if that matters)
my / is now over 90+ big and i cannot understand why since i only use minimal applications for certain reasons.
df -h shows:

i examined everything via du and df commands, then tried gui (mate and ncdu) and nothing...

fyi

find . -maxdepth 1 -mindepth 1 -type d -exec du -sh {} \; | sort -rh | head

leads to...
