System Monitor does not launch

  • 772

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)
system-monitor 18.04

    As suggested from comments:

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

    worked for me.

  2. 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.

  3. If sudo snap get gnome-system-monitor gives an error, probably something went wrong during the upgrade, thus just do: 

    sudo apt install --reinstall gnome-system-monitor

    and reboot.

  4. 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:

    https://launchpad.net/ubuntu/bionic/+source/gnome-system-monitor

    Maybe a sudo apt-get install --reinstall <package> helps and then reboot your machine.
