This is a mime cache issue resolved using

sudo update-mime-database /usr/share/mime

and performed logout and then login, now all icons are back

  • on my Lubuntu 18.04 missing icons on launch bar which I have after reboot during apt update were fixed after second reboot

I add the same ! I was caused by a fail update of linux kernel. My /boot folder was full.

To check that : In a terminal, type

df /boot

if it is full (100%), you can clean it using this tutorial : http://ubuntuhandbook.org/index.php/2016/05/remove-old-kernels-ubuntu-16-04/ Look at "Remove Old Kernels via DPKG".
