Assistance to cleanup, please ?

[Externet]

My compfuser reported being low in storage.  I run Ubuntu 24.04 Linux in very lean way and makes no sense to me being low of free hard drive space (SSD)

Is there a command to safely delete the old, already updated versions that may still reside useless in the hard drive ?

What is 'var' apparently using 58% of storage ?  Its contents being mostly 'lib' as 97% of 'var' as below ?  Do I need 'snap' ?  How can I inspect each file in there to delete it or keep it ?

What is

Can you run in the terminal:

dd if=/dev/zero of=file bs=1MiB count=1024 oflag=direct,sync status=progress

or

sudo dd if=/dev/zero of=file bs=1MiB count=1024 oflag=direct,sync status=progress

(for example, in your home directory)

???

Make screen-shot or copy'n'paste result here..

 

Then

rm -rf file

when you are done,

25 GB is definitely not enough for modern standards.. Where did you get this HDD from? It's doubtful that it's an SSD drive..

The easiest way to solve the problems is to buy a 2.5” SSD with a capacity of 120 GB, for example, on eBay.

I am getting such 120 GB SSD here, used one for $4 (four dollars). A brand new 120 GB is for $14

(120 GB is the lowest size sold now)

 

According to the chart, most of the data is in system libraries. It is not clear which libraries are used by which applications. If you remove them, some applications may stop working..

 

$4 isn't much (unless you live in Africa, which I'm sure you don't).

At this price you will get a new 120 GB drive that will have ~ 5x more capacity than what you have at the moment..
Looking at the specs of the T430s in 2012 they were sold with 128GB - 180 GB disks the lowest version.. So what happened?

The entire T430s used one with 180 GB SSD is for $38 here.

 

To remove the application, use

sudo apt purge

Try also

sudo apt-get autoremove

Thank you. 

In the middle of action showed it again masking the result:

Both commands show:

The replacement of the drive with a bigger costlier or not is not a problem.  But I used years ago ~40MB drives every time upgraded versions since 05.10 almost yearly (kept a bunch archived)  and in an even older laptop that behaved always very happy.  Yes currently have a SSD instead of the mechanical hard drive.

And, as instructed; done:

-Answered no as is insignificant-

The point is learning what is inflating and if is because am doing something wrong; or the updates do not erase/delete the older versions occupying space.  I have very few applications in a lean machine, not even Firefox nor Chrome nor mainstream nor social anything.
