I’m using the Sweet Plasma theme with Candy icons and Latte Dock.
Pamac just refuses to use the appropriate icon, even when I put the full path to the icon in its .desktop file.
I don’t have this issue with any other app in latte, assuming an icon exists for it. Even picking the “Software Update” in my app menu, which just opens directly to the update tab in pamac shows the correct, but different, icon.
This is the desktop file:
[Desktop Entry]

Comment=Add or remove software installed on the system
DBusActivatable=true

Have you tried installing the icon set into the root account? You would just need to log out and back in as User:root Password:whatever you set it as. Then grab the icon package and drop it into usr/share/icons. Then reboot. Probably not necessary the last part but just in case. Then log back into your user and see if anything changed. Just be careful manipulating things logged in as root.
