Hi,
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?

Anders

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.

Alex

The script does care. When installing astap it downloads the 32 bit version - there is an error in the makefile concerning the g17 map file. The makefile is missing _astap in the end of the filename three times. I don’t know if there are more places it favours the 32bit Ubuntu.

Anders

Anders,
Issues with ASTAP are expected given that it is not installed from repositories.
How about kstars and indi - are they installing and running?

Alex

I decided to cancel as I had a problem with the AP creation (not sure what happened). Creating the AP just froze - are you supposed to interact somehow?

I’ve started all over with the 32bit Ubuntu.

Anders

No, it should not freeze. I think you made the right decision - there is not much benefit from 64 bit here.

Alex,

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.

Cheers,
Arjan

Ok, I installed everything on 32bit Ubuntu using the AstroPiMaker4 file. I rebooted after creating the AP and loaded up the VNC viewer from my Mac. That did NOT look good! 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?

Anders

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.

Did you configure VNC viewer to use 24 bit color and best quality? Can you share screenshot?

Yep. After yet another reboot it looks good. But it's really slow. Lag on everything (even just dragging a small text document from one window to another is lagging. My Pi is placed one or two meters away from my computer. But could it be the Raspberry Pi's WiFi signal, that's not that great?

Ok, I just tried using VNC through the ethernet connection instead. That's faster, but still lagging a little bit (but it's nothing alarming). Is there a way to get the Ubuntu server to do the following concerning network connections:

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....
