Upgrade from Zorin 17.3 to Zorin 18 failed

Installing Zorin OS
1

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.

Can You show the Error that You get during the Upgrade?

I really didn't get a error message, it just said that it couldn't complete, and wanted me to send error message which I did. That was all part of the installer. Never got a explanation or error code.

Do You have any Third-Parts Repos added to Your System? Do You have added any Third-Party Gnome Extensions?

There are some Dependency Issues ... And You don't have any Third-Party Repo's added to install something? Did You installed a different Desktop Environment?

10

This is a KDE package, so definitely third party Repo's added.

You can verify with:

ls /etc/apt/sources.list.d

I have not installed a different Desktop environment.
This laptop is an older dell tat was running Win 8. It runs Zorin 17.3 okay.
I did have trouble with Brave but that was due to the Graphics adaptor. I found a fix for that in this forum. I always check for updates before taking on new projects such as upgrade/updates.

12

I am not sure about this. I am using zorin as downloaded, I did not modify it. My screen shows planets, the desktop is the same it has always been. The only problem I had was with Brave something to do with the graphics adaptor, found a solution in this forum.

How about

cat /etc/apt/sources.list

Everything above looks fine.

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...

Thanks, I will give this a try. I thank you for you help and support. I've had a couple of stokes so not as sharp as I used to be.

Sorry, to hi-jack the thread.
I have been following the thread, as I have exactly the same issues.
Following Aravisian's comment, I have carried out the instructions with the result that the upgrader is now telling me all is good to go.
So nice one.

I did as you suggested and it worked. I was able to upgrade 17.3 to 18.1. This dell has a real lousy graphics adapter and I had to put in a fix in 17.3 to get Brave to work. After the upgrade to 18, I was able to lower the resolution so brave worked. Everything else went smooth.
Thankx again for the help.
