Need elp freeing up some space

[jpc2769]

I was trying to upgrade to 18.04, but it told me I need to free up space in my / partition. Partition is 21GB, about 17GB is used. Unfortunately Muon won't open, so I can't really get in and look at what I can/should install.

Also, I used ncdu to look at the directories, apparently /kdecache-jason is 1.1GB. What is in here, can I remove it? How do I?

Thanks!

In a Konsole you can use

du -sch * | sort -h in /var/tmp/

to find out what app or process may be creating the largest files.

To delete the kdecache files you can use the method described here:

but use sddm in stead of kdm.

To have 17GB in use is rather unusual, around 12GB is usual.
There is a chance .deb files have after installation not been removed, run a terminal (Konsole) and execute this command to remove any no longer needed files:

sudo apt autoremove

You can clean the apt package cache (/var/cache/apt/archives/), which tends to grow quite large with the default apt settings:

sudo apt clean

If the default apt settings are used, no debs are stored in /var/cache/apt/archives once the pacakge has been installed successfully: https://askubuntu.com/a/926850

But the default apt-get settings will keep debs in /var/cache/apt/archives until they're removed with sudo apt-get clean.

At least that's my experience.

That's a good catch.

I use aptitude for package management, and that still caches packages by default, so I wasn't aware "apt" doesn't behave like "apt-get" in this regard (by default).

Do you know how the graphical package managers behave? (I don't have any of those installed).

another possible place to save some room in the / partition is by deleting old kernels. They take up a lot of space. I usually delete all but the last two installed.
there are several programs that can clean the drive for you.
Ubuntu-cleaner works well and cleans unwanted kernels also. get it here : https://www.omgubuntu.co.uk/2016/12/...er-janitor-app
and Stacer also works well found here: https://github.com/oguzhaninan/Stacer/releases download the appimage and make it executable and run it without installing.
good luck.

Just checked: installing via Muon retains debs in /var/cache/apt/archives. I don't know if there's some preference or setting to change that. I really don't use Muon and so there might be ...

I don't have Discover on this system but I'll try later on in a VM.

Edit: Discover retains debs as well.

And baobab is a utility to graphically display what is using space on a partition, it is fashioned after the Windows utility sequoiaview.

But there's qdirstat which is just great!
