It is a bit difficult to name exact package name with icons.
So I provide single long command to reinstall all icons-related packages:

sudo apt install --reinstall $(dpkg -l | grep -i icon | grep ^ii | awk '{print $2}')

In the command above:

• dpkg -l | grep -i icon | grep ^ii | awk '{print $2}' is a long pipe with:

  • dpkg -l shows the list of all packages;
  • grep -i icon shows all text lines with icons;
  • grep ^ii shows only installed packages;
  • awk '{print $2}' shows package names;
• sudo apt install --reinstall $(...) is used to reinstall packages from the output of $(...) command.

You can consult man-pages - man dpkg, man apt, man grep, man awk for details about used commands.
