I have researched this and come up with several different answers, but nothing solid.

I had installed Kubuntu 18.04 LTS on my laptop two years ago. Shortly afterwards, I had removed the Akonadi/Kontact suite of apps and several other components that are unnecessary for my use. It took me quite a while to go through all of the deps and figure out what I could and could not safely remove - I don't want to spend the same amount of time figuring this out again if I don't have to.

#NOTE 1: I've not had any issues related to these removals.

#NOTE 2: I am not running my system as an experiment, I need it for work and am not interested in any surprises; nor am I interested in "try this and see what happens".

My system:

• O/S: Kubuntu 18.04 LTS
• KDE: 5.12.9
• KDE Frameworks: 5.44.0
• Qt: 5.9.5
• Kernel: 4.15.0-128-generic
• CPU: i7-8750H
• RAM: 8 GB

My question:

Now that Kubuntu 20.04 LTS is available, is there a way to upgrade only the existing components on my system to 20.04 LTS, or will an upgrade also re-install the previously removed components?

I've searched the web as well as this site (including the other Stack Overflow/Exchange/etc. sibling sites) and have not found any concrete info. I've also searched the official KDE site and have still not found an answer.

I'm running Kubuntu 18.04 on a Lenovo Y7000 laptop with the following:

• KDE Plasma 5.12.9.
• KDE Frameworks 5.44.0
• Qt 5.9.5
• Kernel 4.15.0-128-generic
• Intel i7-8750H
• 8 GB RAM

I had run KMail for several years and I really liked the interface and all of its features. What I did NOT like was the fact that Akonadi and Kontact, etc., seem to be required for KMail to work. KMail was the only component that I ran from this Akonadi mess and I have no desire for any of the other components launching (in the foreground OR background) and stealing resources from my system. Because of this, I had uninstalled KMail, Akonadi, Kontact and several other components about a year ago.

#NOTE: After the removal of these components, I have had no problems; this suggests to me that I had not removed anything necessary for my system to run properly.

My question is this: Can I reinstall ONLY KMail and run it as a "standalone" program, or do I have to have all of these additional, unwanted components install, as well?

Thanks in advance for any help!
