Snap mounts should be hidden from System Monitor

Bug #1749007 reported by Ads20000 on 2018-02-12
This bug affects 6 people
Affects Status Importance Assigned to Milestone
gnome-system-monitor (Ubuntu)
Andrea Azzarone
libgtop2 (Ubuntu)

Bug Description

* Impact
snaps mount at listed in the system monitor but they are an implementation detail and not interesting there. We already filter them out of the Disks UI, we should do the same in the system monitor

* Test case
- have a snap installed (wshich is true in the default installation of Ubuntu)
- open gnome-system-monitor
- check the filesystem tabs content, snaps mounts shouldn't be listed

* Regression potential
Check that the system mounted partitions are still correctly listed


As per the snap mounts in System Monitor should be hidden just as they're hidden from GNOME Disks. Perhaps they should be grouped under a dropdown of / (though this would require developing a new feature)?

It is going to take some time to merge the patch upstream. For the moment the patch in the attached debdiff should make the work.

The attachment "libgtop2.debdiff" seems to be a debdiff. The ubuntu-sponsors team has been subscribed to the bug report so that they can review and hopefully sponsor the debdiff. If the attachment isn't a patch, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are member of the ~ubuntu-sponsors, unsubscribe the team.

the patch looks fine but it's a bit weird to add the new argument to the function to the begin of the arguments and not the end, though the API is not public so it shouldn't really matter. It looks fine to me for a SRU so I'm going to sponsor it this week

I've followed the instructions at with pinning and /bionic-proposed and get 'E: Unable to locate package libgtop2' :( Could someone who knows the proper procedure update that article or what am I doing wrong? :)

Sebastien Bacher (seb128) wrote :

You maybe tried before the package was actually built?

You can also try by downloading the debs on

$ wget
$ sudo dpkg -i *.deb
$ gnome-system-monitor

but that's testing the deb version of gnome-system-monitor, the snap is going to be rebuilt to use the change...

It's work but I installed the standard gnome-system-monitor not the snap.

The verification of the Stable Release Update for libgtop2 has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.

Same problem in Ubuntu Cosmic and Disco with gnome-system-monitor snap version. Problem does not occur with .deb version. but why the snap version is default?
