On a fresh install of 18.10 I attempted to install CPU usage widget

https://extensions.gnome.org/extension/120/system-monitor/

on that link it errors showing :

    On Ubuntu 22.04 clone the repo https://github.com/paradoxxxzero/gnome-shell-system-monitor-applet and do the manual install as per

    sudo apt install gir1.2-gtop-2.0 gir1.2-nm-1.0 gir1.2-clutter-1.0 gnome-system-monitor

cd /tmp  #  could be anywhere ... once installed repo code not used
git clone [email protected]:paradoxxxzero/gnome-shell-system-monitor-applet.git

cd gnome-shell-system-monitor-applet
make install
reboot

    If above fails on Ubuntu 22.04 then just use https://extensions.gnome.org/extension/3010/system-monitor-next/

    Below is for 20.04 or earlier ...

    First install this (its what appears in your error popup):

    sudo apt-get update
sudo apt-get upgrade
sudo apt-get install chrome-gnome-shell

    However, on a new OS install you will still get errors until you also install these:

    #  Ubuntu 20.04
sudo apt-get install libproxy1-plugin-networkmanager gnome-shell-extension-system-monitor

# Ubuntu 19.10
sudo apt-get install gir1.2-nm-1.0

    Or:

    # pre Ubuntu 19.10
sudo apt-get install gir1.2-gtop-2.0 gir1.2-nm-1.0  gir1.2-clutter-1.0

    Then bounce your GNOME Shell by typing:

    • Alt+F2, type r then Enter.

    or bounce from a terminal by running

    killall -3 gnome-shell

    Now go back to

    and turn on the monitor extension. The resource monitor widget will now appear on desktop top status bar.

    UPDATE On Ubuntu 20.04, after doing the above, if it errors out, run the following in a terminal:

    wget https://raw.githubusercontent.com/paradoxxxzero/gnome-shell-system-monitor-applet/fac6b7646346264bd75813a9d606dd5ba5152d6b/system-monitor%40paradoxxx.zero.gmail.com/extension.js -O ~/.local/share/gnome-shell/extensions/[email protected]/extension.js

    Then bounce your GNOME Shell using:

    • Alt + F2, type r then Enter

    I have run fresh installs of Ubuntu 20.04 on a handful of laptops and some work others fail to run this so the mystery continues...

    UPDATE2 Apparently if you are running Chromium as a Snap in Ubuntu 20.04, this is a known bug. Using Firefox one can circumnavigate this issue and it should work.

    PS and yes this also works for Ubuntu 21.10 ( as of May 21 2021 )
