Public bug reported:
After upgrading Ubuntu from 17.10 to 18.04.1 I can no longer start
gnome-system-monitor or any of the other snaps named «gnome-*» (that
were installed automatically).
Trying to open System monitor using its icon, nothing happens apart from
a spinning mouse pointer appearing for a few seconds.
Trying to run «gnome-system-monitor» from the terminal fails immediately with
this output:
«
/snap/gnome-system-monitor/51/bin/desktop-launch: line 23:
/home/mathias/.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)

This is the output from «snap list»:

Running gnome-calculator, gnome-characters, gnome-logs or gnome-system-
monitor using «snap run gnome-calculator» etc. gives similar results –
with one exception: gnome-system-monitor is the only one that gives the
«Permission denied» line quoted above. Interestingly, simply running the
command «gnome-calculator» works. Maybe I have it installed both as a
snap and as a normal application?
I tested following the instructions for gnome-system-monitor and gnome-
logs, and that does indeed fix the problem for those snaps, and I can
now launch System monitor normally. But there should of course be no
need for me to fix this in the first place.
I filed this bug using «ubuntu-bug snapd» as it is obviously related to
snap, but I am by no means sure that this is where the problem is. I
have installed all available updates.
«snap version» gives the following output:
«
snap 2.34.2+18.04
snapd 2.34.2+18.04
series 16
ubuntu 18.04
kernel 4.15.0-29-generic

I am happy to provide more information to help get this issue fixed.
