The `gnome-system-monitor` package preinstalled with Ubuntu 18.04 appears to have a problem with excluding `/dev/loop*` mounts from the File System tab.
This is a screenshot of what it shows on my system:

As you can see, there's a lot of `/dev/loop*` entries, and a lot of duplication of available disk space percentage.
This is a pastebin of `$ mount`: https://paste.ubuntu.com/p/T4ZKz99CdK/
And this is a pastebin of my current `snap` version and `$ cat /proc/self/mountinfo`: https://paste.ubuntu.com/p/3wvsFmnygw/
# How to reproduce
If your version of `gnome-system-monitor` is the default installed with Ubuntu 18.04, you should already have this problem. If not, try removing the current version `sudo apt remove gnome-system-monitor`, and installing it from the snap store `sudo snap install gnome-system-monitor` to have the problem show up.
It could be helpful to look into `$ cat /run/mount/utab` (I'm mentioning this only because it was suggested to me to mention it). Unfortunately I didn't do that before removing the snap package, so I don't have the output available.
# Expected behaviour
I would expect to only see the actual partitions in my system, in my case: `/`, `/home`, and `/boot/efi`, since I have `/home` on its own partition.
# Workaround
A workaround to get rid of this problem is to remove the snap package and install it via apt `sudo snap remove gnome-system-monitor && sudo apt install gnome-system-monitor`. It worked for me, and after that I only had the three partitions mentioned above showing up in the File System tab.
Plus, I do have the output for `$ cat /run/mount/utab` this time: https://paste.ubuntu.com/p/tJwqjDW6T6/ |
