My PC has Ubuntu 18.04 installed.

It does not want to launch the System Monitor.

This seems to be an OS related issue. I have launched it before and it worked fine. Possibly due to some updates it has stopped working.

I am not looking for a solution. I just wanted to report this and I hope the issue will be remedied soon with an update.

I would like to know whether other people have the same issue with 18.04.

More info:

  • I try to launch it via: Super+A, open System Monitor. No errors. For a few seconds the "loading circle" tries to convince me that there is an attempt to launch it. But then it disappears and nothing happens.

  • I am not sure whether this is the command to open from the terminal, but when I run gnome-system-monitor, it tells me:

/snap/gnome-system-monitor/41/bin/desktop-launch: line 23: /home/sandu/.config/user-dirs.dirs: Permission denied
You need to connect this snap to the gnome platform snap.

You can do this with those commands:
snap install gnome-3-26-1604
snap connect gnome-system-monitor:gnome-3-26-1604 gnome-3-26-1604

(the '3-26-1604' number defines the platform version and might change)

    The error message says what you need to do, run the following commands: snap install gnome-3-26-1604 and snap connect gnome-system-monitor:gnome-3-26-1604 gnome-3-26-1604. – pomsky Jun 11 at 10:07

    Yes, but please understand my frustration: it worked fine before. It should work fine without me moving a finger. Why is it that it has stopped working? Why do I have System Monitor in the Applications if it does not even launch? This looks like a bug to me. A minor one, but it is. – Sandu Ursu Jun 11 at 10:33

    The issue is Ubuntu shipped snap version of system monitor with 18.04. This issue is specifically due that decision. If you want a hassle-free fix, consider removing the snap version (snap remove gnome-system-monitor) and install the traditional one (sudo apt install gnome-system-monitor). – pomsky Jun 11 at 10:41

As suggested from comments:

snap remove gnome-system-monitor
sudo apt install gnome-system-monitor

worked for me.

I had the same issue. The gnome-system-monitor is now available as a snap and it appears an update either broke something or didn't change everything properly (I don't really know why it stopped working).

A solution is to reinstall the snap (using snap, not apt) with

$ snap remove gnome-system-monitor
$ snap install gnome-system-monitor

Doing this will install/connect the System Monitor properly and it will work once again from both icon and terminal.

Is some package-dependency not solved ? For system-monitor there is package rsyslog (or rsyslogd ? ) necessary.

You should install it with:

sudo apt-get install --reinstall rsyslog

Am not sure if this is today correct, because this was a while ago necessary. You might check further dependencies here:

Maybe a "sudo apt-get install --reinstall " helps and then reboot your machine.
