This motivated me to try it a few times in a row. On the fourth attempt I get a different message:

You are about to add the following PPA:
Officials KiCad 6.0 releases
For the moment, 6.0.0 was not released. Only RC is available.
More info: https://launchpad.net/~kicad/+archive/ubuntu/kicad-6.0-releases
Executing: /tmp/apt-key-gpghome.iHu9bGFIeS/gpg.1.sh --keyserver hkps://keyserver.ubuntu.com:443 --recv-keys FDA854F61C4D0D9572BB95E5245D5502FAD7A805
gpg: key 245D5502FAD7A805: "Launchpad PPA for KiCad" not changed
gpg: Total number processed: 1
gpg: unchanged: 1
At the moment I’m not motivated to put much effort into this because of the incompatibility of V5.1.12 and V6.0.0-rc.
I can install KiCad-nightly V6.9.9, and that is probably good enough if I’m proofreading the “Getting Started in KiCad” guide, and try some things if they’re not clear. I just won’t update screenshots from V6.9.9 (Unless of trivial things).
For the rest I can wait until KiCad V6 has been released officially.
If its not there is points to some CDN issue. Maybe try again in a few hours.
I’ve loaded the source into Ubuntu 20.04 and it works 100%.
6.0 stable is released and it should install.

KiCad V6 has been working properly for me for some days now.
I don’t know what happened with the launchpad repository, but apparently it’s been fixed.
I don’t care much about loosing KiCad V5 myself, although if there are lots of forum questions related to KiCad V5 and some Appimage is easily installable, then I may install it just to look up some things to answer forum questions. But it’s not high on my priority list.
I would also be very interested to hear from @jsreynaud on that topic. Our company runs entirely on V5 and I would like to investigate the switch to V6 knowing I can still work on V5. @leoheck suggested it should be doable if the old packages had the version appended to the end (eg. kicad-5 or similar), it seems to match the information I’m finding.
It is quite scary to update to V6 with the changes to the symbol and schematic formats. Not because of lack of backups, but because there is no easy way to downgrade the version if V6 starts to act up and we’re seeing discrepancies on our projects compared to V5. Or is there an easy way to go back to 5.1.12 using PPA that is document somewhere?
EDIT: I have tried to downgrade from 5.1.12 to 5.1.10 to no success:
$ sudo apt-get install kicad=5.1.10

You cannot downgrade to 5.1.10 using the PPA because the PPA only keeps the most recent release of the 5.1 series.
I don’t think that there is a way in Ubuntu to easily have both kicad v6 and kicad v5 installed. That said, it is easy to downgrade to 5.1.12 if you decide to.
Hey, @eeintech I was trying to survive with this temporary solution myself. But Kicad is pretty big to keep downloading libs every time. So this was not good for me, even if I have a good internet connection everywhere. I just don’t like it.
Now, kicad-5 could be made available AS IT IS the kicad-nightly. It would be just a matter of replacing the --nightly suffix with the -5. It would be great during this transitioning time. It is not that much of an effort to provide this since the nightly already created this solution.
I hate to say that. Companies are pretty slow to change things. They are pretty slow to even try the change. Most of the time they are even afraid of trying. Now, there are people like you and me that do everything possible to learn and keep the new functionalities coming. With that said, It would HELP A LOT the community if people could TEST the v6 while still using v5.
Now, talking about this Kicad 6. It is a good tool. Full of features. It looks it is pretty slow, something is not right on Linux. But the change is not that hard if you already know how Kicad works. And since the files are textual. It is possible to look for issues. Most of the time, issues were on my custom libs. There the issue was with variables I was using to refer to my custom 3d models and these variables were not replaced automatically. Then I had to make sed on my .kicad_pcb and also in my libs to fix this issue. Libs are easily converted to the new version of Kicad. This is awesome. Schematics in the board can be updated from the newly converted lib by updating components in the EEschema all at once.
I was more worried about 3rd party tools that are still in process of migrating to Kicad v6 if any. The Kicad project conversion is pretty simple and straightforward. For instance, I cannot use kiri since I cannot export schematic on Kicad-6 (plotgitsch is not adapted yet to the new Kicad-6 schematic file type)
Hey @eeintech, I have a script to install and load Kicad 5.1.12 in a folder while Kicad 6 is already installed in the system. I put it here https://github.com/leoheck/parallel-kicad-5.1. It is pretty easy to install and use. Feel free to test it. my preliminary tests show that this works fine.
AppImage is a single file self containing all the needed resources… It can run without conflict with other versions and libraries…
It is the same concept of the portable apps in win…
Then you can i.e. run kv5 Appimage and having installed kicad stable v6 side by side… that’s it
