Another thing: in my search of Linux partitioning tools I discovered, on the site Geeks for Geeks, two GUI partition management tools that allegedly offer "data integrity," meaning I could repartition a device without losing data on the partition(s) affected by the repartitioning operation. The ones recommended to me are GParted and the KDE partition manager. I am running in a KDE environment. Would anyone recommend either of those two partitioning tools?

If you can, show people actual command outputs, it'll make it easier to help.

Do you have any flex with LVM or are your filesystems directly on block devices? e.g.

root@fedora:~# pvs; vgs; lvs

Review your mounts/filesystems, e.g.:

root@fedora:~# lsblk

Understand where your space is being consumed on the / device. Don't use '-h' so you can sort easily, use 'x' so as to limit your 'du' to a single device. e.g.

root@fedora:~# du -xk / | sort -n -k1 | tail -20
1480504 /usr/lib/python3.12/site-packages/azure
1561480 /var/spool/abrt/ccpp-2024-04-27-13:17:11.106624-89698
1602284 /opt

2184720 /var/spool/abrt
2226356 /var/cache
2344592 /usr/lib/python3.12
2344592 /usr/lib/python3.12/site-packages
3429168 /usr/share
4395972 /usr/lib
5354284 /usr/lib64
9976580 /var/lib/flatpak/repo/objects
9980444 /var/lib/flatpak/repo
10041060 /var/lib/flatpak
14354904 /usr
33858716 /var/lib/libvirt/images
33858724 /var/lib/libvirt
44206592 /var/lib
49862812 /var
65976164 /

(Optional, `du -xk / | sort -n -k1 | tac` if you prefer your output the other way round...)

Next, is any of that stuff you don't need? So in my example, I could look at my libvirt images, or flatpacks (which I will, because I'm not specifically using any, to my knowledge.)

Do you have logs you can rotate/archive from /var (if /var's on your / drive rather than its own block device / partition.)

Do you have any Yum cache lying around from old major version upgrades?

What's on the filesystem that *isn't* owned by a package, should it be there?

Everyone:

I have a problem upgrading to Fedora 41. After I download all the
packages and import the keys, it's telling me I need around 5 GB more
space on the / filesystem. The / system is on a partition that has only
50 GiB total, and 395.2 MiB free. (I use the GiB and MiB symbols
deliberately.) Specifically it says I need to find 4437 MB on that
system. If I have to repartition, I understand that I might as well do a
fresh install. My data is safe enough - it's on a completely different
physical device, mounted as /crypt - and another petition on the "root
device" is present with 47.4 GiB free (there's nothing on it but the
contents of /home). But I can't remember half the stuff I installed from
non-core repositories like rpmfusion, and if I have to install from
scratch, I'll lose a lot of applications. (The kernels are on /boot,
which is a 1.0 GiB partition that has more than 500 MiB free.) How can I
free up that extra space (say, 5GiB for good measure) without having to
reformat the root device for a fresh install?
