I am finding it impossible to uninstall some applications:
-Chess (preinstalled)
-KDE connect
-Librem 5 Tour (preinstalled)
-Tootle
-Meteorology (preinstalled)
-Flatseal
From the store tells me that the application is not found and from terminal tells me the same thing. can someone share me the exact command that works to remove each application please.
I take it that when you tap and hold on the icons, the menu that has “View Details” and opens the PureOS Store and the apps page with a neat little trashcan icon for uninstalling is not working on these specific apps? Does that offer to install or uninstall them?
These are not all defaults and some I guess are Flathub installs…? Hard to see what the common problem could be.
With chess, I think the package name was gnome-chess, so the removal command would be sudo apt-get remove gnome-chess. Does that work?
perfect for the application of chess has worked, and yes, the problem is that when I’m in the PureOS store and I press the trash is when the error appears and I can not remove the palicaciones. so I have to do it for sure terminal. this is why i asked the commands. but chess is deleted thanks. 
I think Tootle and Flatseal might be flathub apps, so it’s a flatpak uninstall [+ package name], and you can use flatpak list to see what package names you have.
The other apps are just a matter of identifying the package name.
And btw. see also: Dose my Librem 5 have a broken installation and do I need to reflash?
sudo apt remove gnome-chess kdeconnect tootle phosh-tour gnome-weather
