I have done some testing and so far everything seems to be working.
I have no idea why, but 20.04 seems to be much faster than 19.10.
Everything is available from PPA and installed just fine. Doing some testing right now.
I updated my AstroPiMaker4 script and instructions for building astroimaging system using RPI4 and Ubuntu 20.04.
Here are the features of the script:
- Installs most commonly used Astrophotography software: INDI, Kstars, PHD2,CCDCiel,Skychart, Astrometry with sextractor, ASTAP plate solver
- Sets up Wireless Access Point
- Sets up x11vnc to be started automatically with headless operation
- Defaults to Gnome Desktop, but KDE and Mate can also be installed
More details and script itself are available under:
Feel free to use and fork.
I was able to install all indi drivers.
Can you try again?
I am using 32 bit version.
indi-full includes all indi drivers and it is unlikely you need all of them. Try to install only needed drivers.
I am using syncthing which syncs my images from Pi to desktop almost in real time. It is free and available for most OS
Does the camera save images in CR3 format? If so, it must be the reason for your issue.
Not sure about Kstars, but CCDCiel supports CR3, here are the instructions on how to make this work:
It is possible that Kstars may work too using the same method.

1) If ethernet is connected, WiFi signal is disabled
2) If no ethernet, then enable WiFi and look for a known WiFi (eg. my own WiFi at home) and connect to it
3) If no known WiFi is found, then use the RP as an access point.
I can't even seem to figure out how to connect the Ubuntu server to my home WiFi....
Connecting to your home Wifi should be easy as long as you disable the Access Point.
Regarding the rest of your questions - Access Point of my build is based on create_ap project which is pretty popular.
I suggest reading their documentation or ask a question on their forums.
Keep in mind that it is just a shell script, so I am sure it can be easily modified for your needs.

I developed a script which installs all imaging software I use plus KDE by default or mate as on option.
The script and instructions are available here:
I had to rebuild my imaging Pi4 about a month ago and I used the latest Ubuntu Server 19.10 images.
I updated my scripts on
as part of this rebuild.
The issues I observed in the past are solved now and after several imaging sessions, I can conclude that the system is very fast, stable and reliable.
Feel free to use and/or fork and let me know if you see any issues.
Looks like the good old Ubuntu Mate distribution is still lacking support for RPi4. I don't think I will ever go there again - much safer and faster getting the images directly from Ubuntu, given that all groundwork of building the system from Ubuntu Server image is now completed.
BTW, Mate is getting really long in the tooth and I am switching to Gnome 3 on my computers.
It is running surprisingly well on RPi4.
"Dash to Panel" and "System Monitor" Gnome extensions are making Gnome work very similar to Mate.
They are included as part of my script.
Interesting, is the AstroPiMaker4 script only for the Pi4 or also for other Pi's?
I have a Pi4 running Astroberry, but also a number of Pi3B+ which I might be able to test this stuff on (if it works).
Have you thought about xrdp instead of VNC? For me RDP appears to be more responsive graphically than VNC.
I do not see a reason why it would not work - it is based on the standard Ubuntu image which supports Pi3 too.
I tried xrdp in the past but I did not like it. I also tried NoMachine long time ago, also had some issues.
I feel that given that VNC is available out of the box and always works for me , I did not try anything else recently.

It looks like something from the late 80's or start 90's when it comes to color and graphic and text - like something from the good old Commodore 64 days. Text not clear and everything running very slow. I didn't experience this with my old setup (using Raspbian and the AstroPi3 script). Am I missing something here?
Did you configure VNC viewer to use 24 bit color and best quality? Can you share screenshot?

Are you still getting the Ubuntu hack from the James Chambers source?
I saw on the Ubuntu site ( ubuntu.com/download/raspberry-pi ) that regular 32bit and 64bit server builds (18.04.04) for Pi4 are up for download.
I used to use the hack but is no longer needed.
My latest script under github.com/avarakin/AstroPiMaker4 is using official 32 bit Ubunty 19.10 server installer.

I’ve started all over with the 32bit Ubuntu.
No, it should not freeze. I think you made the right decision - there is not much benefit from 64 bit here.
Issues with ASTAP are expected given that it is not installed from repositories.
How about kstars and indi - are they installing and running?

I've just got a RP4 4GB that I want to use instead of my current 1GB (or is it 2GB?) RP4. I decided to give the AstroPiMaker4 script a spin. Is there a particular reason that it uses the 32bit Ubuntu version and not the 64bit?
Good question. In the past, 64 bit was challenging. Keep in mind that the script does not care if it is 32 bit or 64 bit, so feel free to try and report back.
Before doing this, please check if PPAs have 64 builds of kstars and other software.
