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?

and what desktop do you advise?.

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 did it the old fashioned way, starting from the server and sequentially building up the system and my system is also quite stable now. No reason for me to switch that I can see.
But I am looking forward to hearing the experience others might have.
Of course, by now the official Ubuntu system is 20.04.....
