Some apps not opening on CentOS 7

Question

I've some apps on CentOS 7.5 with GNOME that won't open when clicked. The Weather app for example, when clicked, it seems to load, but does nothing.. it doesn't open.

I found a similar issue here, saying the file /usr/share/gnome-shell/extensions/apps-menu@gnome-shell-extensions.gcampax.github.com/extension.js should be changed on line 77 with value this._app.open_new_window(-1);, but i found it's already changed.

It has already open on the beginning of installation but for some unknown reason it's not opening anymore.

There's likely another process that's running that's blocking it or there's a file that's blocking it, such as a lock file.

In a terminal you can try launching it manually to see what's up.

$ gnome-weather

If you don't see anything specific using that method, then you need to start tracing it. I typically do it like this:

$ strace -s 2000 gnome-weather

Debugging with strace can be a little daunting, so start by looking at your /home directory to see if there's a file that's blocking it.

$ strace -s 2000 gnome-weather  |& grep -E open | grep -i /home

Then look at /etc & other directories to see if it's hanging on any particular file access (read/write).
