Gnome Desktop no Longer Shows Application Icons on Upgrade from F25 to F26

[Stephen Morris]

Hi,

I have used dnf system-upgrade to upgrade my F25 system to F26 and 
now all the shortcuts on my Desktop no longer display their configured 
icons, they display a text page icon instead. Under KDE they continue to 
display fine.

I tried looking at the properties of the thunderbird shortcut, 
clicked on the text icon to navigate to where the thunderbird icons were 
and re-selected the icon, but that made no difference to the icon 
displayed. Why is the upgrade from F25 to F26 now refusing to display 
proper icons for the shortcuts?

regards,

Steve

Try turning on the executable permission.

That shouldn't be necessary, they were all executable before the 
upgrade, so they should still be executable after the upgrade, and they 
still are.

Since I posted this mail I've had a further development on this front. I 
have now discovered that with the upgrade to F26, Gnome, unlike KDE, has 
marked every application on the Gnome desktop as untrusted, so before I 
can actually run them I have tell Gnome to trust and launch them. Having 
done this Gnome then displays icons for the application (which I might 
add Dolphin displayed by default when navigating to the desktop 
directory), but not necessarily the icon that was displayed before the 
upgrade.

Why is Gnome in F26 marking all applications on the desktop as 
untrusted, and from my perspective, for no good reason?

Is it possible that this is because I had to do both the dnf 
system-upgrade and required reboot afterwards twice before Fedora would 
actually install the 2500 - 3000 files?

I have observed this as well. They show up as untrusted also if you try to
execute them out of Nautilus.
