Disk space issues

I have disk space issues, but I have plenty of space in my home
directory.
I use the default options in Trisquel 7 when you ask the installer to
encrypt your hard drive.
My disks look like this:
$ df --human-readable

I recently installed GNOME. This might have used a lot of space. How
do I remove it safely, without getting rid of Trisquel's GNOME desktop?
To get rid of some junk in /, I emptied the garbage in Guix:
guix gc

Unless you installed heavy video games, 17G is quite a lot for the root filesystem. You can use the "Disk Usage Analyzer", in the "System Settings", to discover what consumes that space. Do you remove older kernels? Also, aren't the loop devices (what are they? snapshots that guix keeps?) actually on the root filesystem? Do you need them all?
I always remove legacy kernels from Trisquel, Debian, or Devuan, Fedora etc, but also Parabola removes legacy kernels automatically, afterwards I never play heavy games which I partition every systems to 16 GiB filesystems in ext4.
Finally what are the loop devices? My own SSD only has sda and luks devices, but this is also my first time hearing loop devices.

All I have is Minetest, I think. TeX Live is 8 GB, but I don't have
that either.

Dong that gives file permission errors. I ran it as root.

Does Trisquel's graphical updater do that?
I've never looked in /boot. Let's see.

It looks like there are a few vmlinuz's in there with different version
numbers, so maybe there are old kernels taking up space. I don't think
they're taking up a lot, though.

I don't know where they are located, but they're probably from Snappy
and not Guix.

You are certainly running the 4.4 kernel ('uname -r' would tell) and can remove the two 3.13 kernels, e.g., using the "Synaptic Package Manager" in the "System Settings". But that would only save tens of MB.
What takes 58% of the root partition (according to the "Disk Usage Analyzer") is the /gnu directory. I believe Guix populates that directory. I do not use Guix (and do not have a /gnu directory). Users of Guix can probably help you free space in /gnu.
In a couple of weeks/months I had 8GB of wasted space merely out of kernels... I have kernel 4.9 and is constantly being updated, so I had a lot of them laying around. When I got rid of them I got 8GBs of free space back ;)
