[SOLVED] LXLE-18.04.3-64bit - How to set up weather location, please?

Sorry, I wasn't able to find a better section for this question.
Since LXLE is based on Ubuntu, I hope, it's ok here...

On top of the desktop of LXLE-18.04.3-64bit, there's an icon for a weather forecast, which is set to a wrong location.

How can I fix that, please?

From their wiki:

Terminal Weather open a terminal and enter gksu pluma /usr/share/applications/weather.desktop change wttr.in to something appropriate based on the manual https://github.com/chubin/wttr.in save changes, panel icon may not take effect until restart or readd.

Also, see http://wttr.in/:help

That command doesn't work, because since this is an Ubuntu 18.04.x,
there's no gksu and there's no such a file inside that folder.

EDIT:
Sorry, I was wrong...well, partly.

I found the wanted file in

~/.local/share/applications

Then, I was able to add my town.
