If you’ve installed an icon theme in Ubuntu you might find that your ‘Places’ menu still shows your old icons. This is a known ‘bug’ in Gnome and will hopefully be fixed in the next release.

In the mean time here’s the simple fix so your ‘Places’ menu icons match the rest of your theme!
Open up a terminal. Done that? Good. Now copy ‘n’ paste the following lines: –

sudo rm -f /usr/share/icons/gnome/scalable/places/inode-directory.svg
sudo rm -f /usr/share/icons/gnome/32×32/places/inode-directory.png
sudo rm -f /usr/share/icons/gnome/24×24/places/inode-directory.png
sudo rm -f /usr/share/icons/gnome/22×22/places/inode-directory.png
sudo rm -f /usr/share/icons/gnome/16×16/places/inode-directory.png
sudo rm -f /usr/share/icons/gnome/icon-theme.cache 

Finish up by using this command:

sudo gtk-update-icon-cache -qf /usr/share/icons/gnome

Restart and when you log back in the ‘Places’ icon should now match your icon theme
