No, with Ubuntu 20.04 i have issues with wakeolan and i don't want to use snapd.
Kstars seems to work fine with Ubuntu 20.04 (tested with my desktop on Kubuntu 20.04).

I've found an another solution for my problems of park/unpark:
- Install indi drivers 1.9.1 (latest)
- Get the 1.8.9 indi sources
- Get the 1.9.1 indi sources
- copy indi-lx200_OnStep 1.8.9 in source code of indi 1.9.1
- Compile indi 1.9.1
- Copy the compiled indi-lx200generic in /ust/bin/

And it's work \o/ Park and unpark are OK.
