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:

1. the complete process stopps because sbig-indi (I need it) cannot be found? I commented it out.
2. chromium-browser installation lags several minutes. I commented it out.
After the installation process a nice pink fox was visible via VNC
It take long time until the built-in wireless adapter was visible in the system.

I used the same server image and just built up the system from there by adding Gnome and MATE desktop environment and other components I wanted.
Crashes may be dependent upon the peripherals that are connected. With my Nikon D3300, I would get these random crashes. When I use my ASI1600MC-Pro instead, so far it looks a lot more stable.
There are still a few idiosyncracies, though: For instance, I cannot Polar align if I choose the mount to go towards the East. Then everything crashes at the solver stage. I need to restart and slew to the West ONLY. Then there is no crash and the solve completes fine.
That could also be mount specific, though, have only tested on iOptron SmartEQPro+ so far.
Anyway, why are you trying to use Ubuntu 19, if 18 gives you full RAM and USB functionality?
