I have recently dual booted my pc with ubuntu and windows and total space available for lonux was 39GB . It worked fine for 4-5 days but suddenly showing low dsk space with only 2.1GB left even without installing anything. I have tried cleaning up cache ,old kernels and ended up in freeing only 0.6 GB space. How to clean up this remaining space?
/usr
and/var
combined is about 15 GB, so maybe using up 35 GB is odd. I also have a swapfile at/swapfile
(swap partition if you're using an older version of Ubuntu) that is 2 GB. How big is your swapfile? If you don't have a program that is taking up disk space over time (i.e.,ncdu
should help find that), you might be fine to ignore the warning. – Ray Jun 23 '20 at 6:47
