Hi everyone.
I’ve been having a number of issues after upgrading to 18.04.
The new lightdm slick greeter wasn’t even installed initially. I had to install it myself by purging all greeter from 16.04 and then installing the new slick greeter. I don’t think the config tool is installed either.
I’m also lacking a majority of the panel layouts. I’ve only got openSuse and GNOME2 present in the Mate Tweak tool.
My sources.list file didn’t update either. I’ve created a backup of my old sources.list file, deleted it, and generated a new one by ticking some boxes in Software & Updates.
This is currently the entirety of my sources.list file:
deb http://security.ubuntu.com/ubuntu/ bionic-security main universe
deb http://archive.ubuntu.com/ubuntu bionic-updates main universe
deb http://archive.ubuntu.com/ubuntu bionic main universe
Are there any steps I can take to ensure that I’ve actually got the latest packages installed on my system?
To add to this, some of the panel widgets aren’t working, e.g the TopMenu panel applet doesn’t appear when added and ends up crashing upon maximising a window.

This does not look well but you can try the following.
First, edit your sources.list:
sudo pluma /etc/apt/sources.list
and replace all its content by the following:

# newer versions of the distribution.

Then, reload your sources and upgrade eventual packages:
sudo apt-get update && sudo apt-get dist-upgrade
and try to reinstall the desktop metapackage:
sudo apt-get install --reinstall ubuntu-mate-desktop
Does it reinstall missing packages with that last command?

Thanks for that sources.list file, was looking for a copy of that everywhere.
Reinstalling the mate desktop seemed to do the trick. Everything seems to be installed correctly now.
I was almost tempted to do a re-install, relieved that I won’t need to do that now. Cheers!
