Dell inspiron 3641, currently running Zorin 17.3 core fails on upgrade to Zorin 18 core. The only previous trouble I had was with Brave because of the graphics adaptor, which I found a fix for in this forum. I sent the info in as requested by the upgrade when it failed.

All that looks good too. The package in question is not a part of Zorin OS. It may be left over from some other package... sudo apt remove libkf5khtml5 sudo apt clean && sudo apt update && sudo apt upgrade Then run the Zorin Upgrader to test...

Upgrade from Zorin 17.3 to Zorin 18 failed

Installing Zorin OS
