18.04 LTS - Launching gnome-system-monitor from icon gives snap error

[jimpye]

All

Brand new install 18.04 LTS on brand new laptop. All works exceedingly well. However, I have created a favourite for the gnome-system-monitor on the dock. This was working well, I was regularly checking CPU, Memory etc on the new laptop. However, went to launch it this morning (next day) and nothing happened.

/var/log/syslog is reporting:



May 13 10:49:27 xxxx gnome-system-monitor_gnome-system-monitor.desktop[29538]: You need to connect this snap to the gnome platform snap.
May 13 10:49:27 xxxx gnome-system-monitor_gnome-system-monitor.desktop[29538]: You can do this with those commands:

May 13 10:49:27 xxxx gnome-system-monitor_gnome-system-monitor.desktop[29538]: (the '3-26-1604' number defines the platform version and might change)



At a CLI running running the same gnome-system-monitor command I get same:



$ gnome-system-monitor
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)


Is this a bug worth reporting? What are the ramifications of running the commands suggested? I have not played with snap, so not sure what that last line means about version numbers being a concern.
All the other icons on the dock seem to launch their apps OK. Not aware of any auto updates that might have changed version numbers, I am running with defaults in that area.

Cheers
Jim

just run those 2 commands:

snap install gnome-3-26-1604
snap connect gnome-system-monitor:gnome-3-26-1604 gnome-3-26-1604

[monkeybrain20122]

Or you can just remove it

sudo snap remove gnome-system-monitor

and install the .deb


sudo apt install gnome-system-monitor

You can see which packages are snap by


snap list

Using some of the commands suggested here is some of my forensic investigation. (The teatime snap was installed so I didn't burn the pizza lol)

So it looks like the gnome-system-monitor snap is installed. I am assuming the 1604 at the end of the version number is meaning 16.04 for the previous LTS version.

Anyways. I will try removing the snap and then running the snap install, snap connect commands as suggested. If all falls to big pile of custard, I will try the Apt Repository version.

Again cheers, and thanks for the quick responses.
