After running racket-lang install-script all my /usr/share/application/*.desktop files have broken icon paths and corresponding shortcuts are displayed with question marks. Paths are overwritten like this (for standard terminal):

Icon=/usr/share/racket/utilities-terminal

I'm wondering, if there was a way of broking them at once, maybe there is some easy way to fix them all at once? The problem is I don't know how those paths were looking before. I've tried to replace "/usr/share/racket/" prefix to "/usr/share/app-install/icons/" because I've found this folder has related icons, but this doesn't work until I explicitly specify icon's extension so I can't just write some simple replace script here (icon extensions vary from app to app: in some cases there is "/usr/share/app-install/icons/app.svg", in other "/usr/share/app-install/icons/another-app.png").

You can just change icon path to application name. Try this:

for file in /usr/share/applications/*.desktop; do
    grep 'Icon=/usr/share/racket/' "$file" /dev/null
    sed -i 's:^Icon=/usr/share/racket/:Icon=:' "$file"
done

Save it as a script ('script.sh') and run it as root ('sudo sh script.sh').

It will fix all files which need changing.
